Upgrade your 1971-1976 GM B-Body Caprice or Impala with the QA1 qapBW02-GMB4 Level 2 Big Wheel Kit. This complete bolt-in suspension system is designed to support wheels up to 28 inches while improving ride quality, handling, stance, and rear-wheel fitment. The kit includes front and rear suspension components, adjustable coil-overs, control arms, trailing arms, and sway bars for a coordinated installation that helps your car sit correctly without relying on temporary spacers or repeated part changes. It is compatible with factory rear housings or Quick Performance 9-inch rear axles.
Double-adjustable coil-overs make it easy to fine-tune ride height and shock performance directly on the vehicle. Front ride height can be adjusted by up to 2 inches, while the rear can be set from stock height to as much as 5 inches lower. Independent compression and rebound adjustments allow you to tailor the suspension for comfortable street driving, improved traction, or drag racing. Included aluminum spanner wrenches simplify ride-height adjustments after the kit is installed.
Adjustable upper and lower trailing arms help center the rear axle in the wheel well, creating additional clearance for large wheel and tire packages. Tubular control arms use suspension geometry designed for big-wheel applications and provide a lighter, stronger alternative to stock components. Tubular front and rear sway bars help reduce body roll and improve stability, especially with larger wheels or raised ride heights. Components are powder coated and supplied with the necessary hardware for a straightforward garage or professional-shop installation.
