Our Specialty Shops

Performance parts. Auto repair parts. Interior and exterior accessories. Need we say more?
Our departments have more products for your vehicle per square.

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.

    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.
  • Performance Parts
    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.

    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.

    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.

    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.

    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.

    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?

    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.

    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.
  • Performance Parts
    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.
  • Performance Parts
    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.

    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.

    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.
  • Performance Parts
    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.
  • Performance Parts
    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?

    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.

    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").

    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.
  • Performance Parts
    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.
  • Performance Parts
    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" 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.

    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.

    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.

    If you’ve decided it’s time to replace the clutch on your manual-transmission car, you’ve reached the point where advantages (crisp, new-feeling response) have come to outweigh disadvantages (significant labor costs or time spent doing it yourself). Whether you don’t have a choice because your old clutch slips badly, or you want to take initiative and upgrade your vehicle by sharpening performance off the line, you have high expectations about the finished result once high labor costs are paid or you’ve spent a lot of time and effort doing it yourself. You’re anticipating silky release and take-in of the clutch pedal, smooth running without harshness or vibrations, crisp shifts that chirp tires on pavement, and the fact that your vehicle feels brand new again. Knowing what’s important when a clutch job is being done can get you those results and save you money, because taking shortcuts usually yields disappointment.

    Shock absorbers, also known simply as “shocks” (which is what we will call them for the rest of this article), are the suspension components which stop your car or truck from bouncing up and down after hitting a bump. They are a major contributor to your ride comfort and safety.

    In this article, we’ll introduce you to the specific tools designed to be used when replacing brake components and servicing your brake system. Having the right tools BEFORE you start working on your vehicle makes these types of jobs quick, easy, and doable for the home mechanic. It also prevents having to put things back together before the job is finished because a tool needs to be purchased. Owning the right tools and doing the job yourself will save you hundreds of dollars by sparing you a visit to the repair shop – and much more over the course of a lifetime of brake work.

    Look up "fan belt" in any modern automotive dictionary, and you'll typically find a definition that reads, "An endless belt used to transmit power from a crankshaft-driven pulley to a pulley driving the fan, alternator, or other engine accessory. It is usually V-shaped in cross section with the point of the V fitting into a groove in the pulley".
  • Performance Parts
    An intake manifold is an integrated assembly that sits atop the engine, consisting of a series of tubes which distribute fresh outside air to each and every cylinder. On V-shaped engine blocks, an intake manifold typically sits between the two cylinder banks while inline engines may feature a manifold to the side of the cylinder head. Intake manifolds serve as a mounting point for carburetors, throttle body assemblies, fuel injectors, thermostats, and more depending on vehicle manufacturer engineering preferences. Intake manifolds may also serve to route coolant through dedicated channels in order to remove heat from the engine. Because of their location and functionality, intake manifold assemblies are under constant stress from engine vacuum pressure as well as direct heat from coolant, cylinder combustion gasses, and the cylinder heads to which they are mounted.

    The question of whether to buy parts from an automotive dealer vs. ones from aftermarket manufacturers is as age-old as the automobile itself. Below, we'll take a look at things worth considering to help you make a better choice if you're facing that same question. Automobile manufacturers and dealerships always advertise the fact that their parts are "genuine" because they were made by the exact same production facility that made the parts installed on the assembly line.
  • Performance Parts
    In this article we'll look at the differences between a "transaxle" and a "transmission". In short, a transaxle performs both the gear-changing function of a transmission and the power-splitting ability of an axle differential in one integrated unit. A transmission performs the gear-changing function only, delivering power via a single output shaft at the back of the unit. Although both perform gear shifts in the same fashion, there's often confusion about these two terms because the word "transmission" is sometimes used as a blanket description to include transaxles when it should not be.
