The anti-roll bar, also called an anti-sway bar, connects the left and right suspensions together and anchors to the vehicle frame. Typically used at the front and rear of the vehicle, the anti-roll bar is commonly used to adjust the handling balance of the vehicle and limit the amount of sway or body roll during cornering.
In essence, an anti-roll bar works as a torsion spring, so as you approach a high speed corner, the vehicle will begin to lean downward toward the outside corner pushing upward on the outside end of the anti-roll bar. The upward movement of the outside end of the anti-roll bar is transferred to the inside end of the anti-roll bar, which responds by also applying the same upward movement to the inside cornering of the suspension. This compresses the inside corner of the suspension while also providing torsion to the anti-roll bar so the outside edge can better resist the upward movement. All this results in a vehicle that'll remain level even while making high-speed corners and keep traction more equal for the inside and outside tires.
Whether you're looking to increase performance on your daily driver or looking to have the ultimate autocross/road race machine, we offer a wide array of anti-roll bar products.

Shop by vehicle to view all anti-roll bars offered for your daily driver, autocross or road race vehicle. Also, take a look at replacement shocks and struts to complement your new anti-roll bars by reading, "Which Bilstein Replacement Shock or Strut is Best for Your Vehicle?"
Looking for a complete lowering spring and damper kit that'll add improved handling without a big sacrifice in comfort? Then take a look at the Bilstein B12 Pro-Kit. By combining Eibach's proven Pro-Kit springs with specially tuned Bilstein shocks and struts in one complete package, you can get the best that both companies have to offer for the following vehicles:
-
Late model C- and E-Class Mercedes-Benz
-
Fifth-generation Volkswagen Golf
-
Fifth-generation VW GTI
In nearly all cases, the use of a lowering spring requires replacement of the Original Equipment struts and shock as the higher spring rates are more than the O.E. units can handle. For best durability, switching to a performance oriented shock with heavy duty components will maximize the performance of the spring and eliminate the chances of premature wear. Eibach went to one of the best in the suspension industry and asked them to design a durable and responsive companion for their Pro-Kit spring.
Key Features & Benefits of Bilstein's B12 Pro-Kit:
-
Professional Cornering System
-
Lowers up to 40mm
-
Bilstein monotube gas pressure technology
-
Eibach Pro-Kit application-specific progressive rate performance springs

Not everyone is looking for or needs a stiffly valved adjustable race shock. For those looking for comfort and a return of factory ride quality, an Original Equipment style replacement shock will do just fine. These shocks and struts feature a lower price tag due to a lack of adjustability and features, but aim to stop the bouncing associated with old, worn out or leaking factory pieces.
Of the shocks that fit this criteria, my favorite is the KYB GR-2/Excel-G. Featuring shock valving that is typically no more than 10% stiffer than factory, these shocks add a splash of performance without over-doing it. Add in a cost-effective price point and an industry leading warranty and you have a combo that is tough to beat.
It should be noted that the KYB GR-2 is not intended for use with aftermarket lowering springs. If you have these springs installed on your vehicle and are looking for an alternative to a KONI or Bilstein product, I suggest you check out the KYB AGX Adjustable. It features more aggressive valving and 4-8 way adjustability depending on the application.
KYB products are manufactured for a wide range of light-duty passenger vehicles including cars, trucks, SUVs, and vans. Find a KYB product that's right for your vehicle.
