QA1 Rear Suspension 1970-1981 GM F-Body S-Adj 12-170 R157-170

Ditch those clunky leaf springs and take control of your 1971-1981 2nd Gen F-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 A LOWERED, MORE AGRESSIVE STANCE

Leaf springs limit your ability to achieve the perfect stance and require modifications to tune ride height. Give your Camaro or Firebird a sleek, aggressive, lowered look with QA1’s tubular 4-link. This kit provides an optimized ride height that improves handling, roll center, and center of gravity. QA1 coilovers offer height adjustability that can be dialed in with ease. 

FIT WIDER WHEELS AND TIRES

Designed to work with both standard and mini-tubs, this system offers generous clearance for up to 12-inch-wide wheels and 335 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 AND 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.

Note – Welding required.
