Product Description

The QA1 HK21-GMA2 is a Level 1 full vehicle handling kit engineered for 1968-1972 GM A-Body muscle cars - including the Chevelle, El Camino, GTO, Cutlass, Skylark, and Monte Carlo - powered by small block or LS engines. This kit bundles a front single adjustable Pro Coil coilover system, a rear single adjustable Pro Coil coilover conversion, and a 1-1/4" hollow 4130 chromoly front sway bar into a single, bolt-in package that transforms the factory A-Body suspension with adjustable ride height, tunable valving, and meaningfully reduced body roll - all with no cutting or welding required.

The Level 1 designation makes this QA1's entry-level A-Body handling kit, designed to deliver a significant performance upgrade over stock while maintaining a smooth, comfortable street ride. Spring rates are pre-selected for average weight small block and LS builds; the kit is also available without shocks for those who want to specify their own spring rates. Critically, this kit is fully stageable - every component is compatible with QA1's Level 2 and Level 3 A-Body handling kit parts, allowing you to build your suspension in phases without worrying about compatibility. Register shocks at QA1 before installation to activate the Limited Lifetime Warranty.
