Description

This Level 3 Big Wheel Suspension Kit is designed for 1978-1987 GM G-Body vehicles, allowing fitment of up to 24-inch wheels. It's a complete bolt-in system, including adjustable coil-overs for ride height adjustment (1 inch higher to 3 inches lower than stock), adjustable upper and lower trailing arms for axle centering, and tubular control arms and sway bars for improved front-end geometry. The front sway bar is 4 inches narrower than OEM for full turning radius with 24-inch wheels. No cutting, grinding, or welding is required for installation. The kit works with factory housings or Quick Performance 9-inch rear axles.
