Get your wheel and tire package to fit with adjustable trailing arms that center your rear axle in the wheel well. This gives you more clearance for up to 24” wheels.


Easy, Bolt-In Installation


Parts come powder coated and ready to install with all necessary hardware. We put in extra hours in the R&D shop to make sure there's no cutting, grinding or welding required. Bolt the kit on right in your garage or work with your local shop.


Level 2 & 3 Kits Include:


Tubular Control Arms


Upgrade your front-end geometry for better drivability. These arms are designed specifically for big wheel cars with corrected suspension angles for large wheels and tires. They much are lighter and stronger than stock to get the most out of your car.


Tubular Sway Bars


QA1’s high clearance front sway bar is 4” narrower than OEM bars, providing full turning radius on 24” wheels. It was also designed to work with OEM or notched front frame rails. Rear anti-roll bars reduce unwanted body roll and improved 60-foot times.
