Performance Parts / Replacement Parts

Have a four-wheeler and want to raise it for big tires and off-road clearance? Or do you want to slam your tuner car to get that flush stance? Are you building a track racer or do you just want better handling out of your daily driver? No matter what you drive or what you’re building it for, we have the performance suspension parts that will help you achieve your performance goals, including lift and lowering kits, shocks, springs, sway bars, and more.


Featured Brands

Factory suspension systems are generally a compromise between ride and handling, even on performance cars. The addition of aftermarket performance springs, shocks, and sway bars can improve a vehicle’s stance without affecting ride quality, and dramatically reduce body roll and front end dive for an improvement in handling, braking, and control that you can feel. This results in a car that’s much more fun to drive, and isn’t that what it’s all about?

    If you want to lift a truck or SUV, we offer several ways to go about it. You can get rid of that nose down attitude with a leveling kit, which may include strut extensions, coil spring spacers, or torsion keys to lift the front and make it level with the rear. A body lift will raise the body on the frame and is perfect if you want to install larger wheels and tires but don’t plan on driving off-road. For a rig that’s off road ready, we offer suspension lift kits up to 6” or more that will let you conquer the toughest terrain. Choose from basic kits to the most comprehensive, as well as individual components.

    Car makers have to be conservative with ride height to satisfy bumper height and other regulations. You are under no such constraints, so to get that aggressive stance, lose the ugly gap between the fenders and tires, and improve your ride’s handling, we offer lowering kits. These kits contain progressive springs that will lower the ride height, but still provide a comfortable, albeit firm ride. Comprehensive kits contain firmer shocks or struts, or coilovers, and larger sway bars as well. Besides improving looks and handling, lowering your car can also reduce drag and increase fuel economy.

    Carrying heavy loads in a truck bed or towing a trailer can be a challenge if the vehicle isn’t set up properly, and once loaded you could end up with the headlights pointing at the sky and the rear bumper almost dragging the ground. We offer heavy-duty leaf springs, helper springs, and air springs, all designed to keep your vehicle level and stable, with a comfortable ride, when heavy loads are added. We also offer sophisticated self-leveling suspension systems that automatically inflate/deflate rear air springs or springs at all 4 corners to maintain vehicle ride height.

    Setting up a high-performance machine, especially for the race track, involves more than just shocks, springs, or struts. Reducing chassis flex will improve handling, especially on unibody vehicles with strut towers, and you can tie those towers together for strength and rigidity with our strut braces. Changing suspension height and running other than stock wheels and tires often requires additional parts like caster/camber plates, eccentric bolts, and alignment kits, to get the wheels properly aligned for optimum handling and even tire wear.

    Performance driving puts a strain on all suspension components, so you need parts that will stand up to abuse and come back for more. We can supply you with control arms, ball joints, and torsion bars designed to go the distance. We also offer an extensive selection of polyurethane bushings for every part of your suspension as well as body mounts. Polyurethane bushings are much more rigid than their rubber factory counterparts, for sharper handling and more precise steering. And to make sure vulnerable mechanical components survive off-road adventures, check out our assortment of skid plates.

    • Off-Road Bumpers
      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.

      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.

      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.

      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.

      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.

      Stock vs Performance Suspension
      Very often we don't even realize what a crucial role a car's suspension plays in providing a safe and comfortable ride. The system maximizes the friction between the road surface and your vehicle's tires, ensuring steering stability along with responsive handling.

      Shocks Versus Struts: The Big Answers Revealed!
      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.

      How to Inspect Your Suspension System
      The very first thing to know about timely suspension system diagnosis is that the stability and steering control of your vehicle and, what is more important, your safety on the road depends on how often you make it. Automotive suspension belongs to one of those car systems that are constantly exposed to high loads and thus are prone to wear and tear. Most specialists recommend inspecting suspension system after every 6,500-7,500 miles or when there are any signs of its breakage.

      How Low Can You Go?
      Lowering is high on the list of many people who want to improve the appearance of their car. If you want to lower your car with the coil springs, then replacing them with lowering springs is the way to go. But what if you want to lower your car and also make it handle better? If that’s your goal then consider coil-over shocks.
