Ditch those clunky leaf springs and take control of your Firebird or Trans Am 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.

Leaf springs limit your ability to achieve the perfect stance on your Firebird. 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.

Designed to work with both standard and mini-tubs, this system offers generous clearance for up to 11-inch-wide wheels on ’67-’68 F-bodies and 12-inch-wide wheels and 335 tires on your ‘69. This results in a significantly more aggressive stance and improved traction and performance.

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

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.

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.
