QA1 68-72 GM X-Body Rear Four Link Suspension System - R258-170

Product Overview Ditch those clunky leaf springs and take control of your X-Body with QA1's coilovers and triangulated 4-link. This upgrade improves ride quality, enhances handling performance, and enables you to dial in the perfect stance. With the added benefit of accommodating wider wheels and tires, this kit is the ideal solution for your car. Achieve the Perfect Stance Leaf springs limit your ability to achieve the perfect stance on your Nova. Upgrading to QA1's coilovers and a tubular 4-link provides +2 to -3 inches of ride height adjustability, letting you dial in exactly the look you want. Fit Wider Wheels & Tires Designed to work with both standard and mini-tubs, this system offers generous clearance for up to 11-inch-wide wheels and 315mm tires. This results in a significantly more aggressive stance and improved traction and performance. Note: Achieving maximum wheel and tire width will require mini tubs. Improved Handling and Stability QA1 4-link delivers handling control without compromising your daily comfort. Perfect for both street and track use, double adjustable shocks are famous for their independent rebound and compression tunability, giving you exceptional handling and control and finer control over your suspension. Easy, Installation & Adjustment Thoughtful design meets effortless installation requiring minimal welding.
