Transform the way your 1997–2004 C5 Corvette handles, rides, and responds with the QA1 Rear Pro Coil-Over Shock System. Designed specifically for the C5 platform, this MOD-Series coil-over replaces the factory transverse leaf spring and rear shock assembly with a fully adjustable, high-precision coil-over setup. If you’ve ever wondered whether a C5 can feel modern, planted, and fully tunable — this upgrade is the answer.
QA1 Pro Coil-Over System Details
This rear coil-over kit features QA1’s MOD-Series aluminum shock body paired with 7" 700 lb performance springs. The design lets you independently adjust ride height and damping, giving you complete control over rear suspension behavior. Built to manage aggressive cornering, spirited street driving, or track-day performance, the system dramatically improves weight transfer, rear-end stability, and suspension predictability.
Why QA1 Coil-Overs Are a Game-Changer for C5 Corvettes
Unlike factory leaf-spring setups, QA1 Pro Coil-Overs allow true ride-height tuning and damping control. Corvette owners often ask if a coil-over conversion really makes a noticeable difference — and for the C5 platform, the improvement in balance, traction, and responsiveness is substantial. QA1 engineered this kit around Corvette-specific geometry to maintain drivability while unlocking precision handling.
