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.

  • Why Are Caliper Covers Only Available For My Front Brakes?
    When it comes to creating the right look for your car or truck, a shimmering set of wheels can do more to make or break its appearance than almost any other accessory. The flip side of the coin is when you stand back and look at that new set of custom rims, you suddenly realize brake hardware that used to be hidden is now completely visible - especially disc brake calipers, which tend to discolor and tarnish over time.

  • Convert Old-School Drum Brakes With a Disc Brake Conversion Kit
    Ask any professional automotive tuner or hot rodder about upgrading the stopping power of drum brakes, and they'll tell you to ditch the drums completely and make an upgrade to disc brakes. This kind of swap is performed often in the automotive world, especially on collector cars that have some power behind the wheel. In fact, it's so commonly done that major component manufacturers have been producing brake conversion kits for years - kits that deliver smooth, even stopping power because all the bugs have been meticulously worked out. In this article, we'll cover such drum-to-disc brake conversion kits for popular vehicles from the 1950s through the 1980s, and we'll discuss the benefits you'll enjoy after making the switch.

  • Exhaust Kits | The Easy Way To Replace Your Exhaust System
    If your exhaust needs repair, chances are the section you noticed with a hole in it isn't the only piece on its last legs. Take a close look at that one pipe or muffler that needs replacement, and you'll find pieces on either side of it are usually pretty far gone as well. Corrosion and rust aren't selective - they attack all exhaust pieces equally.

  • What is a Fuel System 'Throttle Body'?
    A throttle body assembly is an integral part of a fuel-injected engine's air intake system. Its function is to regulate the amount of air that flows into the engine - accounting for factors such as throttle (gas pedal) position, idle speed, cold start warmup, and more. To perform these critical tasks, the throttle body is bolted in place between your engine's intake manifold and air filter housing. A hinged metal plate inside the throttle body (known as a butterfly valve) opens to let more air in as the gas pedal is depressed. Because fuel injection systems are inherently computer controlled, information from various sensors mounted on the throttle body allows the vehicle's engine management system to determine the optimum fuel flow rate as based on multiple conditions.

  • Axle Glossary | The A-to-Z List of Definitions
    Whether you're performing a route axle bearing service, replacing a CV drive axle, or overhauling a complete rear axle assembly, you're going to come across numerous terms for Axles and Components. Depending on your knowledge and experience, many of these terms may or may not be elementary. However, because many products use different names for the one part, or one name for different parts, we've created this glossary to help you understand the basic axle components that exist.

  • How To Order Customized Brake Caliper Covers
    If you've got rims that show off the hardware behind them, brake caliper covers will take the look of your ride to new levels. To read more about their advantages, please be sure to see our article "Caliper Covers vs Caliper Paint". There, we highlight the many options you have among your caliper cover choices.

  • Exhaust Clamps, Gaskets & Hangers | Don’t Skimp on the Small Stuff!
    Exhaust system gaskets, clamps, and hanger pieces are probably some of the most overlooked parts on your entire vehicle. Since you don't see them, clean them, or maintain them, they're usually out of mind until they become degraded and fail. And degraded they are, because whenever exhaust pipes and mufflers are replaced, these old support pieces are usually always corroded beyond the point of re-using.

  • Does My Vehicle Have a Mechanical or Electric Fuel Pump?
    From the earliest days of the automobile, fuel pumps have existed to draw fuel out of the fuel tank and move it into your engine's combustion area. (A note for the purists: some very early cars, like the Ford Model T, used "gravity feed", which required the fuel tank to be mounted higher than the engine. These cars could only climb steep hills by ascending them in reverse!)

  • U-Joints: Identification, Selection, and Replacement
    A "u-joint", or universal joint, is a coupling that connects two shafts that are at different angles to one another, in a fashion that allows both to rotate freely without excess friction. Essentially, a u-joint is formed from multiple pieces - some of which are permanently attached to the ends of the shafts themselves. U-joints can be located along driveshafts, 4WD transfer case shafts, and even axle shafts. U-joints are different in design from constant velocity joints, and are sometimes referred to as Cardan joints or Spicer Joints.

  • Speedo Calibrators and Tranny Controllers Let You Re-Engineer Your Ride
    Many auto enthusiasts are driving around with speedometers registering too low a speed because they've mounted bigger tires on their vehicle. This effect occurs because larger tires have a greater overall circumference (distance around the outer edge) than smaller ones do. A tire with a larger circumference will cover more ground per revolution, and it will also make fewer revolutions in a mile than a tire of smaller diameter.

  • Data Monitors and Loggers Provide Access to Important Drivetrain Info
    If you're tuning a modern engine, there's a lot of information you'll need to know in order to make educated adjustments and avoid trial-and-error guesses. Keeping track of air/fuel ratios, fuel pressures, boost pressures, and rpms is difficult at speed, and trying to commit them all to memory is almost impossible - assuming you even have readouts for these items. Maybe all you need to do is closely watch how temperatures and other things are affected by stop-and-go traffic. Or maybe you take your vehicle on track runs. If so, you already know splitting your attention between gauges and driving just causes you to lose focus on both. Because you can't take notes while driving, we offer a practical and effective solution for the tracking of engine data - recording it electronically for later playback.

  • Why Should I Add a Throttle Controller?
    Modern cars and trucks are constantly evolving, mostly due to advancements in electronics. This allows vehicle systems previously controlled by mechanical hardware to be run by computers that have processing power undreamt of several short decades ago. When applied properly, this processing power can wring out higher levels of a vehicle's built-in power and responsiveness, without physically making any engine upgrades. One such system found on today's fuel-injected vehicles is electronic throttle control, commonly known as drive-by-wire.

  • Are Superchips Really Super?
    In today's ultra-competitive automotive world where fuel consumption, horsepower, and emissions are paramount, modern vehicles are controlled by computers in order to meet these opposite and conflicting demands. And presiding over the multitude of separate computers on any vehicle is the ECU (Engine Control Unit) - sometimes called the ECM (Engine Control Module).

  • How To Install Caliper Covers
    If you've fitted a set of aftermarket wheels on your car or truck, you've probably noticed how they show off everything behind them in a way your OEM ones simply couldn't. Your factory brake calipers are now suddenly visible to the world, and odds are they do not live up to the high standards of crisp visual appeal your new wheels and tires have set. Or you may have a nice set of factory wheels which expose the brake hardware, and it's a look that you feel could stand some improvement.

  • Why Do Some Replacement Exhaust Manifolds Come With Catalytic Converters?
    If you're looking for a replacement exhaust manifold, you may notice that the choices available for your specific vehicle are only available with an "integrated" catalytic converter. In the same way, a search for a replacement catalytic converter may only turn up "combination" converter/manifold products.

  • Big Brake Kits Bring The Biggest Stopping Power
    Have you thought about upgrading the brakes on your car or truck to performance brakes? You likely have, as most car enthusiasts consider that sooner or later. This desire may be because of your more aggressive driving style, your dissatisfaction with OE brakes, your vehicle being used to tow a trailer, or even your weekend stints at the track.

  • Skid Plates Provide The Ultimate In Off-Road Protection
    If you take your 4x4 off-roading, you have likely gained an appreciation of how unforgiving trails can be when it comes to your vehicle's underside. Deep ruts with rough edges can appear out of nowhere, sturdy-looking rocks can shift unexpectedly, and tranquil bodies of water can hide everything from sinkholes to fallen tree trunks. Before you know it, the underside of your truck has bounced off something hard enough to damage moving suspension components or puncture housings containing engine oil, gasoline, transmission fluid, or differential gear oil.

  • Here's A 'Tip': Exhaust Tips Are An Easy Way To Dress Up Your Tailpipe
    Performance exhaust systems give you improvements in power output, sound levels, and appearance, all in one package. But let's face it: not everyone has the spare change to buy and bolt up one of these kits. So you soldier on with what you have. And that may be a tired-looking exhaust system that is still functional. You've spent all day washing and waxing the vehicle's paint and chrome to perfection, but no degree of elbow grease will make that tailpipe look better.

  • Tail Light Guards: Good-Looking Protection For The Back End Too
    Unlike passenger cars, virtually all modern pickups, sport utility vehicles, and Jeeps feature squared-off rear corners – a configuration that’s dictated more by necessity than by choice. Positioned on those sharp-edged corners at the most vulnerable spots possible are the tail light assemblies. We use the word vulnerable because tail lights really are sticking out there, with no protection.

  • Lift Your Car Easily And Safely With A Quality Floor Jack
    When working as a do-it-yourselfer (DIY), whether you're a beginner or an expert, having the right equipment to get your vehicle off the ground is a starting point for easier car repairs at home. You work on your own vehicle because you enjoy the experience of improving your car or truck with your own hands, and you do it to save money. With that spirit in mind, we've written this article to cover the very items that help you get started - floor jacks which are the right size, quality, and price for your home garage workshop.

  • 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.

  • Side Steps - Choosing the right Fit, Style, Function
    If you have a pickup, SUV, or a Jeep, then you probably feel, as we do, that 4x4s are attractive in nature and serve as great canvasses for creating an individual vehicle identity. Because the overall shapes of truck designs are unpretentious, lines tend to accentuate strength. And bright work (or black work) applied in the right fashion can heighten bold styling, accentuate luxury, or both. We know that running boards or side steps have potential to make a big impact in this category, and we understand form is just as important as function when it comes to selecting the right ones. That's why we offer a great variety of full-length running boards and step bars as well as short-length steps. We've even got steps that fit easily onto trailer hitch openings.
