QA1 Level 2 Big Wheel Suspension System for 1971-1976 GM B-Body Caprice and Impala (BW02-GMB4)

Fits 1971-1976 GM B-Body models including Chevrolet Caprice and Impala. This complete bolt-in suspension system is engineered to accommodate wheels up to 28 inches while significantly improving ride quality and handling geometry.

The QA1 Level 2 Big Wheel Kit replaces restrictive factory components with high-strength tubular steel and adjustable damping. The included double-adjustable coilovers provide independent control over compression and rebound valving, allowing you to fine-tune the chassis for cruising or drag racing. Front ride height is adjustable from stock to a 2-inch drop, while the rear can be set anywhere from stock height to a 5-inch drop using the included aluminum spanner wrenches.

To ensure proper wheel fitment, the kit includes adjustable upper and lower trailing arms that center the rear axle within the wheel well, preventing rubbing on large-diameter tire packages. The front tubular control arms are designed with corrected geometry specifically for raised ride heights, while front and rear tubular sway bars reduce body roll and increase stability.
