Product Description

QA1 DK31-GMA2 is a Level 1 full-vehicle drag suspension kit designed for 1968-1972 GM A-Body vehicles. The package is engineered to improve launch performance, straight-line stability, and consistency by upgrading key rear suspension components. It is intended for rear-wheel-drive applications and is suitable for performance builds based around average-weight, stock-trim vehicles, including small-block and LS-powered configurations.

The kit combines QA1's 52871 rear sway bar, boxed lower trailing arms, adjustable upper trailing arms, trailing-arm braces, and anti-hop bars. The adjustable rear suspension components allow the chassis and rear axle behavior to be tuned for improved traction, while the anti-hop bars help control axle wind-up under hard acceleration. The components are designed to work together as a coordinated drag-racing suspension package.

DK31-GMA2 is the version supplied without shocks. QA1 specifically notes that the W/O Shocks configuration also excludes springs and thrust-bearing kits, allowing the builder to select dampers and spring rates appropriate for the vehicle's actual weight and racing setup. Front control arms are not included in this Level 1 kit. The package covers the applicable 1968-1972 GM A-Body platforms listed above.
