    QA1 HK43-GMX2RN Features:

    QA1's Handling Kit is the premier suspension upgrade for '68-'72 X-Body Nova owners seeking exceptional handling. This kit replaces the front and rear suspension with QA1 MOD series 4-way adjustable coilovers and a narrowed QA1 9" rear housing, and four-link optimized for wider wheels and tires. HUGE HANDLING GAINS Experience superior handling with lightweight control arms that improve geometry and reduce flex. The adjustable four-link design eliminates wheel hop and improves traction and handling. Front and rear sway bars and subframe connectors minimize roll in tight corners. AGGRESSIVE STANCE Factory springs limit stance, but QA1's MOD series coilovers and 4-link offer 2 inches of front adjustability and -3 to +2 inches in the rear for ideal ride height. The kit allows for massive 11-inch-wide wheels and 315mm tires when using mini tubs.
