The QA1 Level 1 Drag Suspension Kit for 1975–1979 GM X-body installations is a bolt-in package focused on better launch control and straight-line stability. Level 1 includes four shocks and carefully chosen spring rates suited to average-weight small-block and LS-powered cars with stock trim. The modular approach lets builders stage upgrades or select alternate shocks and springs later for precise ride height and tuning.
