Description
Modern Handling with a Perfect Factory Fit
QA1’s triangulated 4-link system is designed specifically for early Mustangs, offering a geometry-correct layout that maintains proper pinion angle and eliminates common issues like axle wrap. The result is dramatically improved traction, sharper cornering, and a smoother, more predictable ride. This suspension system is designed to work with 9 Inch Housings (3" Tubes) and ensures a precise fit and the durability required for today’s high-performance engines.
Double-Adjustable Coilovers for Personalized Performance
This kit includes QA1’s renowned DOUBLE-adjustable coilovers, giving you 18 clicks of independent compression and rebound adjustment. With a simple turn of the knob, you can fine-tune your Mustang’s suspension for all-out track day performance, change it up for more comfortable daily cruising, or tighten it up for aggressive handling and spirited driving.
Customizable Ride Height & Stance
Achieve the ideal look and performance with an adjustable ride height that ranges from stock height down to 3″ lower. This flexibility allows you to set your preferred stance while keeping proper geometry, ensuring improved handling without sacrificing ride quality.
