QA1 R158-170 Details

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. Single-adjustable Proma Star shocks let you fine-tune the ride, effortlessly switching between smooth cruising and a firmer, more aggressive feel. Easy, Installation & Adjustment Thoughtful design meets effortless installation requiring minimal welding. You'll experience a painless installation and setup process, where adjusting ride height, pinion angle, or wheelbase is as simple as a few tweaks – no link removal required. No modifications to the floor pan required. Note – Welding required. Best In-Class Lifetime Warranty Register at QA1.net/warranty for lifetime coverage of your QA1 shocks.
