Performance. No matter what you drive, when you're an enthusiast you always want more - quicker acceleration, flatter cornering, shorter stopping distances, faster lap times. However, even if you drive a performance car, you may find that the factory's idea of performance doesn't meet your expectations. That's where we come in. We feel the need for speed just like you do, so we've stocked our digital shelves with the high performance parts that will help you make more horsepower, corner harder, stop on a dime, and cut your lap times, but most important of all, never leave you disappointed. If you're looking for exhilaration behind the wheel, browse our selection of performance car parts and truck performance upgrades and start improving your car or truck's capabilities today.

For some folks performance means one thing: horsepower, the kind of power that pins your spine to the seat back when you mash the pedal. We crave that feeling too, and we have performance upgrades from cold air intakes to camshafts to programmers so you can get the sensation. Feeling the power is essential, but because performance is a multi-sensory experience, it has to sound right too, so check out our huge selection of performance exhaust parts. We have everything from headers to cat-back exhaust systems that will not only let your engine breathe better to unleash the power, but also deliver exhaust tones that are music to the high performance ear.

Unless you only drive in a straight line, going fast requires more than just acceleration. You need powerful brakes, precise steering, and handling that provides maximum traction in the corners. Traction starts where the rubber meets the road and you won't find a better selection of performance tires and wheels anywhere. Performance parts like our drilled and slotted disc brake rotors, composite pads, multi-piston calipers, or complete brake kits will get your car hauled down quickly, while our selection of sway bars, springs, shocks, bushings, and other handling performance parts for cars will help you maximize the tire contact patch for the most traction.

But if your idea of performance has nothing to do with the pavement, you're in luck because we're much more than just performance auto parts. We've got plenty of performance accessories for Jeeps, trucks, and SUVs, from big wheels and gnarly meats to dig into the dirt, to lift kits for tire and obstacle clearance. Our performance transmission and driveline parts includes clutches, transfer case parts, driveshafts, axles and differentials that can withstand any off-road abuse. And because we know many of you prefer your trucks diesel powered, we have a wide range of diesel performance parts like intake manifolds, performance programmers, turbocharger kits, and exhaust systems including "stacks".

Ask anyone that knows anything about performance driving and they'll tell you that the seat-to-steering wheel interface (otherwise known as you) has more to do with going fast than anything you can bolt on under the hood. Performance accessories like our racing seats, steering wheels and pedals will help keep you comfortable and in control at speed. And if you're ready to get serious and test your skills at the track, we have the speedway performance accessories that are required by most sanctioning bodies including helmets, 5-point seat belt harnesses, flame resistant racing suits, gloves, and shoes.

Even if your car doesn't have the horsepower to be a real racer, at least it can look the part. Our body kits and ground effects parts include pieces like front air dams, canards, side skirts and rear diffusers that were originally developed as racing parts, to give your ride that fresh off the road course look, and nothing screams performance like a spoiler and a carbon fiber hood. But don't stop at the exterior; if your cockpit can stand some upgrading we have the custom car parts to make it happen. Monitor your powerful engine's vital signs with a set of custom gauges. We have many styles and lighting options to choose from, and gauge mounting pods for a factory like installation. And since you'll be spending so much time behind the wheel, why not upgrade your tunes with a car stereo receiver, amplifier, speakers, and subwoofer.

  • Hot Under The Hood? Performance Cooling Fans Chase Away Excess Heat
    Auxiliary fans are great for providing a boost to your vehicle's original cooling system if you've encountered overheating conditions. For those who live in climates that see high temperature and humidity, excessively high coolant temperatures can be a major problem - one that will not go away if ignored. Aluminum engine blocks and cylinder heads found on most of today's cars are much more sensitive to overheating than traditional engine blocks made of iron. All it takes is one stretch of time with parts reaching excessively high temperatures to cause permanent metal warpage, leaks, and damage to a myriad of moving parts.
  • Auxiliary Oil Coolers Keep Engine Oil Temperature Under Control
    You may have seen Performance Engine Oil Coolers for sale on our website or elsewhere, and your first reaction may have been "who needs one of those? Not I." We can't say we blame you if your presumption is that either a) your engine is cooled by liquid antifreeze/coolant, so this thing can't be for you; or b) the word "performance" led you to conclude that hot-rodders are the primary target for these add-ons. In fact, if you tow a trailer, or tend to load up your SUV to the max, or drive at high speeds in very hot summer climes, you just might be the real target customer for an engine oil cooler. Allow us to provide some educational background on motor oil, and the critical roles (plural) it plays. Please read on!
  • Caliper Covers vs. Caliper Paint
    One consequence of the trend toward larger diameter wheels is that previously hidden mechanical components are now clearly visible. We are referring, of course, to your brake calipers. These dirty, dusty, and rusty parts used to function in obscurity, but with plus-size thin-spoke wheels, they're now on display for all to see. If you happen to drive a late model performance car with a nice set of multi-piston Brembos, this is not an issue. Nor is it a concern if you have the coin for an upgrade to a performance brake kit. But what about the regular Joe who just blew his wad on wheels and tires; what can he do?
  • Can an Air Intake System also Increase My Fuel Economy?
    We all know that achieving better fuel economy while driving puts money back in your pocket and does the environment a favor. But for those who are actively interested in squeezing the most out of every drop of gas, getting more miles per gallon can actually become a sport - especially if a vehicle has a manual transmission that can be upshifted earlier and put into neutral during downhill grades or when coasting to a stop sign.
  • The Real Cost of Your Car’s Cheap Factory Air Filter
    In today's world, saving money wherever possible has become essential. But it's important not to lose sight of the fact that, sometimes, a product that costs more up front will save you more money over time. In our business, we've seen far too many consumers judge products solely on the basis of their initial cost, completely neglecting any long-term economy and benefits. When it comes to automobiles, "performance" air filters are a perfect example of this.
  • Why is it important to do a brake fluid flush?
    If you've ever visited an automotive dealership service department, you may have been told that your vehicle needs a brake fluid flush. Or you might have received a coupon mailer offering this service for a discounted price. Maybe you thought it was an attempt on the part of the dealer to separate you from your money for something you don't really need. After all, you have made the effort to learn more about your brakes, and you understand that occasionally, the brake pads and rotors will wear out and need replacing. However, you've never heard of a "brake fluid flush".
  • My Car is Brand New | Why Should I Change My Air Intake System?
    Aftermarket air intake systems have become one of the most popular engine modifications available for late model cars and trucks. An easy question to ask is why are these so popular? After all, didn't engineers who work for your vehicle manufacturer spend years developing the best engine components available? Since power and fuel economy are major selling points these days, it's hard to imagine car companies not doing everything they can to maximize horsepower, miles per gallon, or both.
  • What are the Different Types of Air Intake Systems?
    There are many types of aftermarket air intake systems that range from simple and inexpensive to elaborate. In the scope of this article, we'll examine the different types of air intakes, what they do, and look at a few specific product examples of each. But in short, performance air intake setups increase airflow into your engine - boosting combustion and creating more horsepower and torque that you can actually feel. Their relatively low cost and easy installation (bolt-on in most cases) keeps them in popular demand by car enthusiasts that own everything from 1.5-liter turbo motors to big block V8 engines.
  • Which Performance Brake Pads Work Best On My Car?
    The brake pads which were installed on your car or truck when it was new are "fine" - fine for the average Joe who is driving an unmodified vehicle. But YOU, the auto enthusiast, you know better. You have made various drivetrain mods, or have converted your truck into a towing rig. You've added bigger wheels and tires and now want brakes which won't leave such a mess on the shiny rims. You recognize that you need to improve the "stop" to accompany the "go". The first, and easiest, item to move up to is a set of performance brake pads.
  • How To Replace Disc Brake Pads
    Disc brakes have been the most common setup on modern vehicles for decades, with just about 100% of today's vehicles using them in the front, and many cars and trucks also equipping the rear with disc brakes. The brake pads are the wear items which will need attention sooner or later; there will be wide variations in brake pad life depending on the vehicle, driver, driving style, etc., but rough estimates are that front pads will need attention every 15,000-30,000 miles, with rear disc pads lasting 50,000-100,000 miles.
  • How much lift is needed for larger tires on my 2007-up Jeep Wrangler?
    Twenty years after the first Jeep Wrangler model debuted in 1987, third-generation Wranglers were introduced for the 2007 model year. Unlike any previous Wranglers or CJs, a 4-door Unlimited model (known internally as the "JKU" body) was offered alongside the standard 2-door ("JK" body). Because it took the off-road capability Wranglers are known for and broadened it with the practicality of 4 doors for those needing a family vehicle, third-generation Wranglers have proven very successful in the marketplace. Maintaining Jeep tradition, this Wrangler appeals by offering a higher-than-average number of advantages for the 4x4 enthusiast, whether it's used for rock crawling or as an everyday driver.
  • Glossary of Brake Terminology
    Whether you're looking to replace worn brake pads and rotors or delving into more detailed brake repairs or upgrades that involve new calipers, proportioning valves, master cylinders, vacuum boosters, and more, you will come across a lot of different terminology when it comes to brake components. Depending on your knowledge and experience, a lot of these terms may be elementary. However, because many of them use similar words but represent completely different things, we've created this glossary to help you understand exactly what you need, and what you don't.
  • Coilovers Are Pricey - Why Would I Spend My Money For Them?
    When first glancing through the Performance Coilover Kits section of our website, you may be put off by some of the prices you see. After all, what are you buying other than a combo set of springs and shocks under some fancy name? Certainly, you ask yourself, can't you purchase springs and shocks separately and monetarily come out ahead?
  • Body Lifts & Suspension Lifts From 2 to 10 Inches | What are my Lift Kit Choices?
    Has this happened to you? You catch a glimpse of a truck like yours in a parking lot or around town that, for some reason, you like better than your own. It seems to have a stance that's more rugged-looking and more suited to a 4x4 than yours does. Maybe you get a chance to stop and take a closer look immediately, or maybe it's days or weeks before you see the other truck again.
  • What Special Tools Are Available For Suspension Repair?
    Seasoned professional automotive technicians often say if you're using too much physical effort during a repair, you're simply not using the right tool. This is true, and a perfect example is repairing and replacing suspension components. If you've ever done this type of work or attempted to do it, you know it can be trickier than merely loosening and tightening bolts.
  • Coil, Leaf, & Torsion Bar | Describing The 3 Different Kinds of Springs
    The springs in your vehicle probably aren't something you think about until there's a problem or you've decided to upgrade suspension parts in the interest of sportier handling. But what specifically do springs do? In short, they play a major role in the safe handling and ride comfort of your vehicle. Not only do they keep a vehicle at a designated standing height, they provide recoil necessary to bounce back after suspension components move up and down over uneven road surfaces. By themselves, springs will continue to bounce up and down for a long time unless a motion damper such as a shock absorber is present to keep things stable. Springs can be soft and extremely bouncy, or they can be stiffer and less bounce-prone.
  • How Do Shock Absorbers Work?
    Shock absorbers (also known as "shocks") are the suspension components which slow, then stop, the up-and-down bouncing movement of your vehicle's springs through a process known as dampening. Without shocks to calm things down, springs will continue to extend and release energy they absorb from bumps in the road at an uncontrolled rate - bouncing for a long time until their kinetic energy finally dissipates. Needless to say, this would produce an extremely bouncy ride that would be hard to control over uneven road surfaces.
  • Glossary of Off-Road Terminology
    If you're looking to beef up your 4x4 to take it off-roading, chances are you've been reading about all the ways it's possible to improve a truck and get it ready for the trails. There are so many different approaches to the subject and so many differing opinions, your head may start spinning. We know starting from scratch can be confusing, especially if you're undertaking something you've never been involved with before.
  • Are X-pipes and H-pipes Better Than Straight Pipes on Dual Exhaust Systems?
    You may be wondering why so many aftermarket performance exhaust system manufacturers are offering dual exhaust systems connected by "H-pipe" or "X-pipe" sections. After all, aren't two separate pipes, or so-called "true duals", the best for performance? The answer is no, but to understand why we have to examine how a typical internal combustion engine works.
  • Are Headers Worth The Performance Improvement?
    Engines have often been compared to air pumps, because the engine that’s most efficient in terms of economy and power is the one that can get air in and out of its cylinders the easiest. That’s why most performance modifications like conical air filters, cold air intake systems, headers, and cat-back exhaust systems are aimed at making the intake and exhaust systems less restrictive. These parts increase the flow of air into the engine and ease the flow of exhaust gas out of the engine. Among these components, headers may be the most difficult to install. In this article, we’ll discuss what headers do, their different types, and how much performance they can add to your car.
  • Power, Sound, Looks | Can I Have It All With a Cat-Back Exhaust System?
    It's an age-old question that many have asked. Will an aftermarket exhaust be worth the expense? While they definitely can be, an important question to ask yourself is do you care more about the deeper sound they’re designed to produce, or the added performance gained from being less restrictive? As car enthusiasts, we’ve become accustomed to associating the sound of a car with its exhaust. After all, doesn’t everyone have a childhood memory or two of a car and the particular sound it made?
  • Suspension Enhancements Will Raise The Rear Of Your Tow Vehicle
    If you are using your "daily driver" car or truck for occasional towing duty, you are looking for that ideal sweet spot where the weekday commute is comfortable and quiet, and the weekend trailering feels solid and secure. In other words, you don't want to vehicle to feel too "stiff" during the week, nor do you want it to ride "soft" when pulling a trailer.
  • Performance Transmission Coolers Keep Your Temperature Down When Trailering
    Recent data from USA Today states that only 6.5% of new vehicles sold in the U.S. are equipped with manual transmissions. The reverse of that means 93.5% of all new cars and light trucks are sold with automatic transmissions. Therefore, the odds are that your ride has an automatic. A less-known fact about those transmissions is that they all have built-in oil coolers, and the vehicle's radiator does double duty, shedding heat from both the engine coolant and the transmission fluid (ATF, or "automatic transmission fluid").
  • Pickup Truck Cab And Bed Sizes Are Important When Selecting Accessories
    Americans love to have choices. Buying a dress shirt? Decide solid or stripe, short or long sleeve, cotton or poly blend, button or spread collar, regular fit, slim fit, or big & tall. How about a meal at your favorite steak house? Will it be porterhouse, T-bone, or sirloin? Cooked rare, medium-rare, or medium? With baked, mashed, or French fried potatoes? Thirsty for a fancy cup of coffee? Let's not even get started on options that let you end up with a "grande caramel macchiato with 1% low-fat milk, 2 Splendas, and an extra espresso shot".
  • Stanced Wheels, Demon Camber | How Do I Get That Look?
    Stanced. Demon camber. You may know it as oni-camber. You've seen the look, and whether you like it or not is totally beside the point. The great thing about this stanced look is that it gets your attention. From the interviews we've read with owners and drivers of these machines, that is exactly what they are after. They've said that it's all about being noticed.
  • The Benefits of a Performance Ignition Distributor
    Since their inception at the start of the 20th century, motor vehicles with gasoline burning engines have needed a precise way to deliver an electrical spark to each of the engine's cylinders. (Note that diesel engines do not rely on an electrical spark to ignite the fuel-air mixture.) For much of the past 100 years, the spark has been delivered by the ignition distributor. The distributor is always mechanically linked or timed to the engine's rotation so that the spark is sent at the exact moment it is needed.
  • How To Replace An In-Tank Fuel Sending Unit
    A Fuel tank sending unit is a term for the mechanical assembly inside your fuel tank which measures the level of liquid in the tank, then reports its findings to the fuel gauge on your instrument cluster. All sending units contain a "float" piece which does just what it describes - floats atop the surface of the fuel. Many automakers design the float piece as an attachment on a hinged arm that pivots as the level in the tank rises or drops. Others design the float piece as a cylinder that rides up and down around a metal shaft.
  • Antifreeze Explained: What It Does And Why It's Needed
    "Antifreeze" is a chemical, primarily consisting of ethylene glycol, which when mixed with water serves to lower the freezing point and raise the boiling point of the mixture. Traditionally, the combination of antifreeze and water is known as "coolant". As opposed to air-cooled vehicles which rely on fan-driven air blowing over engine components, water-cooled engines use a radiator, water pump, thermostat, heater core, hoses, and passageways within the engine.
  • Disc Brakes and Drum Brakes Explained!
    If you have owned a car or truck for more than a few months, you are undoubtedly aware that your vehicle's brakes occasionally need replacing. Let's face it, we can be hard on our brakes. Highway speeds, stop-and-go traffic, and heavy cargo loads are some of the more significant factors which increase brake wear.
  • Glossary of Engine Internal Parts
    Internal combustion engines are extremely complex and feature a wide array of components that rotate, move up and down, pump, seal, or remain stationary. When repairing or rebuilding your engine, you will come across many different terms when referencing repair manuals and ordering parts. We know it can be confusing, especially when the repair is complex. Even if you are paying a professional to do the work, it’s good to be conversant with the topic. In order to help you understand the terminology of engine components, we’ve created the following glossary, listed in alphabetical order.

Super Buy
I just bought the Curt Q24 with rollers for my 2011 F-350 SB and I absolutely love it. A lot sturdier than my old plate. The roller bars are made out of solid steel not hollow tubes like my previous hitch. Overall I absolutely love it theirs a lot more beef that comes along than expected it weights a bit much for one person to handle but I'm okay with that.
