HK43-GMX2RN Level 3 Handling Kit with Narrowed 9in. Housing, 68-72 GM X Body

PRODUCT OVERVIEW

QA1’s Handling Kit is a complete suspension solution for '68-'72 X-Body Nova owners aiming to achieve the absolute best in handling performance. This kit replaces front and rear suspension, featuring QA1 MOD series 4-way adjustable coilovers and a 4-link setup optimized for wider wheels and tires, along with a custom QA1 9" rear housing for peak performance.

SIGNIFICANT HANDLING IMPROVEMENTS

QA1’s lightweight tubular control arms equipped with low-friction ball joints and composite bushings minimize flex and improve front end geometry for superior handling and response. The adjustable four link design eliminates wheel hop, improves traction and offers predictable, tunable handling. Front and rear sway bars along with subframe connectors tie the chassis together to keep the car planted in the most aggressive of corners.

AGGRESSIVE STANCE

Factory springs limit stance, but QA1’s MOD series coilovers and tubular 4-link provide up to 2 inches of front adjustability and -3 to +2 inches in the rear, allowing for ideal ride height. The four-link kit and included, narrowed, housing allows the ability to use massive 11-inch-wide wheels and 315mm tires.

Note: Achieving maximum wheel and tire width will require mini tubs.
