QA1 Level 1 Big Wheel Kits

QA1 Level 1 Big Wheel kits contain everything to give your GM B-body or G-body the ideal stance, plus improved ride quality. Each kit will include front and rear single adjustable Pro Coil system coilovers and an aluminum spanner wrench to dial in the exact style you want. The single adjustable valving allows you to firm up or soften the ride with the simple twist of a knob.

QA1 Level 1 Big Wheel kits also include adjustable upper and lower trailing arms that center your rear axle in the wheel well, granting more clearance for larger wheels. Additionally, tie rod adjuster sleeves and a thrust bearing kit complete the kits. The components are powdercoated and ready to install with the necessary hardware, making your installation hassle-free. Choose the kit designed for your vehicle.
