QA1 67-73 Ford Mustang Pro Front Coil-Over System - Double Adj. - 10in x 450lbs/in - Aluminum

Upgrade your classic Mustang with modern suspension performance using QA1’s Front Pro Coil System. Designed specifically for 1967–1973 Mustangs, this kit delivers exceptional handling, ride quality, and stance control. Featuring 10” coil springs with a 450 lb./in. rate, it’s tailored for heavier ’67–’73 cars, offering the strength and balance needed for street performance, restomods, and spirited driving. TOTAL CONTROL WITH DOUBLE ADJUSTABILITY QA1’s double adjustable shocks give you independent control of rebound and compression, each with 18 clicks of adjustment. This allows you to fine-tune your Mustang’s ride and handling for different driving conditions — from comfortable cruising to track-ready precision. RIDE HEIGHT FLEXIBILITY Fine-tune your stance with ride height adjustability from factory stock height down to 2” lower. Whether you want to maintain a stock look or drop the front end for a more aggressive appearance, QA1 coilovers let you do it without sacrificing drivability. EASY BOLT-IN INSTALLATION Engineered for a true bolt-in installation, this system requires no welding or cutting. With premium hardware and powder-coated springs, it’s built for durability and installs with standard tools.
