Upgrade your classic Mustang’s suspension with QA1’s Pro Coil System. Engineered for 1964–1966 Mustangs, this single adjustable coilover kit offers modern handling, ride quality, and stance adjustability in a straightforward, bolt-in package. Featuring a 10” coil spring with a 400 lb./in. rate, it’s an excellent choice for restomods and street-driven cars that need sharper handling and improved control. MODERN HANDLING & CONTROL Factory suspension designs limit tuning and performance. QA1’s single adjustable coilovers let you fine-tune rebound and compression together with 18 adjustment settings. With one knob, you can soften the ride for cruising or firm it up for aggressive driving, giving you the flexibility to match your Mustang’s style. RIDE HEIGHT FLEXIBILITY This system allows you to adjust ride height from factory stock height down to 2” lower. Whether you’re keeping an original look or going for a lower stance, QA1 Pro Coils let you achieve the right height without sacrificing suspension geometry or drivability. EASY BOLT-IN INSTALLATION No welding or cutting required. QA1 designed this system as a direct bolt-in replacement that installs with basic hand tools, making it a perfect upgrade for DIY enthusiasts.

About - QA1

Since 1993, QA1 has been an industry leader in High Performance Suspension and Driveline for the automotive aftermarket and various other industries.

QA1 specializes in high-performance suspension components, including shock absorbers, rod ends, spherical bearings, struts, springs, ball joints and other related items. With products to fit a wide variety of applications, they have solutions for the circle track, drag racing, street performance, and street rodding markets.

Coilovers-

​From street to track, seamlessly adjust for any desired performance level. Coilovers deliver a perfect stance and look for your ride. With trusted USA-made quality, backed by a best-in-class warranty, they are a simple, yet significant upgrade for your vehicle.   

Springs- 

​QA1's Pro Coil Systems use uniquely-wound springs specific to various makes and models. These high travel springs are designed for immediate response, increased stability, and enhanced cornering abilities. Durable silver powder coat finish.

Carbon Fiber Driveshafts-

​Changing track conditions don't have to affect your performance. That's why QA1 offers two carbon fiber driveshaft options for super late models, limited late models, and Wissota and IMCA dirt late models. While both provide unmatched performance on any track, they each have their unique features designed to provide extra benefits in specific conditions. Our 3.2'' XMA style driveshaft takes advantage of rough conditions, providing extra alignment to avoid binding. Specifically engineered for tacky or rough conditions, the 3.2" dirt late model carbon fiber driveshafts offer extreme U-joint misalignment (XMA). The tube on this shaft has a higher torsional stiffness that results in less twist, which is great for heavy, fast, or rough tracks where traction isn't limited. The XMA style provides more U-joint misalignment than other designs on the market, and this prevents binding near the pinion yoke, allows more rear suspension articulation and provides more clearance under deceleration, which is especially critical when the car is "on the bars" during corner entry. The driveshafts have a uniform wall thickness created by optimum fiber lay up that ensures high RPM stability as well as extreme torque capacities. A thoroughly engineered surface protection is used to withstand extreme racing environments and provide a worry-free performance. The forged yokes are precision CNC machined and are specially developed for QA1's 11 step bonding procedure that ensures a better balance and minimal material waste. All QA1 driveshafts are precision balanced, track tested and proven. They are lighter, stiffer, stronger and safer than steel or aluminum driveshafts, and available in a variety of lengths and with or without a slip yoke. Custom lengths are also available. Made in the USA.​
