QA1 73-71 Ford F100 (Short Bed) Rear Suspension System - R121-170

QA1's unique torque arm design maximizes performance without the inherent binding issues of other systems, all while achieving a 4" to 7" drop. This bolt-in system also offers incomparable adjustability: the watts link, torque arm, trailing arms, bracket mounts, and shocks are all adjustable. Single-adjustable shocks are perfect for street-driven trucks that see occasional time on the track. With a simple turn of the adjustment knob, you can cruise with a super soft setting, or dial up the valving for more aggressive handling for those twisty backroads. With registration, your shocks can be backed with a best-in-class Limited Lifetime Warranty. Keep your rear end housing center in the truck with QA1's unique watts link design. This compact system keeps your tires from rubbing the sides of your bed, while providing clearance for rear exiting exhaust systems. Adjustable lower trailing arms allow you to dial in your wheel base for the perfect wheel and tire fitment inside your wheel well. Parts come powder coated and ready to install with all necessary hardware. You can bolt up the kit right in your garage or work with your local shop. Made in the USA. Fitment Notes: This system only fits short wheel base trucks. Designed to use stock '73-'79 F100/F150 9" axle with iron 3rd member and direct fit aftermarket 9" axles with iron 3rd member. Aluminum 3rd member will NOT work.

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.​
