Description

QA1 Level 3 Big Wheel kits are complete bolt-on suspension systems with control arms and sway bars to give your GM B-body or G-body the ideal stance, plus maximum performance with QA1 MOD Series shocks.

The front and rear MOD Series adjustable Pro Coil coilovers offer maximum shock tunability with high- and low-speed valving adjustability. Perfect for the street or drag racing, MOD Series shocks are for those looking to get the most out of their car.

QA1 Level 3 Big Wheel kits also include control arms, trailing arms, and sway bars for a complete bolt-on suspension system. The components are powdercoated and ready to install with the necessary hardware, making your installation hassle-free. Choose the kit designed for your vehicle.

Features and benefits:

* Front and rear MOD Series Pro Coil system
* Pro Touring upper control arms and Street lower control arms upgrade your front-end geometry for better drivability
* Control arms are designed specifically for big wheel cars with corrected suspension angles for large wheels and tires
* Adjustable lower and upper trailing arms center your rear axle in the wheel well, granting more clearance for larger wheels
* Front and rear sway bars reduce body roll and improve stability, and help reduce handling issues that come from big wheels and raised ride heights
* Tie rod adjuster sleeves
* Spanner wrench
* Canister mount
