Product Overview QA1's Level 2 Handling Kit is a complete solution for X-body owners who love twisty back roads and weekend track day events. This complete solution replaces your entire front and rear suspension, optimizing ride quality and handling performance. The coilovers offer adjustable ride height, while the rear suspension was optimized for wider wheels and tires. Bind Free, Light-weight Front Suspension QA1's tubular front control arms stand out as some of the lightest available in the market. When paired with QA1's double adjustable Pro-Coil coilovers, and front sway bar this kit offers plenty of control over your suspension. Achieve the Perfect Stance Upgrading to QA1's coilovers and a tubular 4-link provides 0 to -2 inches of adjustability in the front and +2 to -3 inches of ride height adjustability in the rear. Fit Wider Wheels & Tires Designed to work with both standard and mini-tubs, the rear system offers generous clearance for up to 315mm tires. Note: Achieving maximum wheel and tire width will require mini tubs. Improved Performance and Stability 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 with a completely bolt-in front suspension and a 4-link 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 floor pan required. Note - Welding required Best In-Class Lifetime Warranty Made in the USA Fitment Notes Wheel and tire fitment should be verified on the vehicle Welding Required Includes Spanner Wrench QA1 Subframe Connectors strongly recommended May require Exhaust Modification
