Looking for a better launch, straight line stability and consistent performance for your 1979-1989 Fox Body Mustang? Turn to QA1’s drag racing suspension kits for a full-vehicle upgrade that fits your needs. Available in two different levels of performance, these drag racing kits offers easy, bolt-in installation and seamlessly works with whatever OE component each piece attaches to. Don’t want to make the investment right away? No problem. You can build your car in stages, using our parts list as a road map to get to the level of performance you want and have the peace of mind knowing you won’t have compatibility issues. These kits include spring rates carefully selected to maximize performance while maintaining a smooth, comfortable ride. They are geared towards average weight vehicles with stock trim. Our level two drag racing kits offer stiffer springs to maximize stored energy for weight transfer. What if the vehicle has been heavily modified from its original weight? No problem. These kits are also offered without shocks and struts to give you the flexibility to order the shocks or struts with the spring rates you want. Please note when ordering the drag racing kit without shocks, the kit will also not include springs, spanner wrenches or thrust bearing kits.
Each component found in the QA1 Drag Racing Suspension Kit is American-made, high-quality material, beginning with the tubular k-member. This high strength, low alloy steel k-member is 50 percent lighter than the factory K-member and corrects roll center when your Mustang is lowered. This K-member also maintains optimum anti-dive geometry with minimized bump steer issues.
To support drag applications on your S197 or S550, the race lower control arms are engineered with X-Series Chromoly rod ends and low friction ball joints. The X-Series Chromoly rod ends give the Mustang a wide wheel alignment range and reduce friction from low friction ball joints. The Front Lower Control Arms will reduce unsprung weight while improving weight distribution in race applications. If you’re still concerned, QA1 added the bumper steer kit to fix unwanted toe change when faced with challenging tracks. The bump steer spacers include inner tie rods that run level and parallel with the steering rack and pinion.
The rear lower control arms are constructed of 0.120-inch wall-cold rolled boxed tubing and the upper control arms are constructed of 1-1/4-inch aircraft aluminum. Keep your tires planted firmly for improved traction and predictable handling thanks to the fluted, greaseable polyurethane bushings on the lower control arms. The spherical rod ends included with the upper control arms feature a pair of rear-end bushings that are constructed from polyurethane and will eliminate bushing bind, allowing the suspension to move smoother for better vehicle control.
***Please note when ordering the drag racing kit without shocks, the kit will also not include springs, spanner wrenches or thrust bearing kits. .
***NOTE ON SPRING RATES FOR ALL KITS:
***Spring rates are carefully selected to maximize performance while maintaining a smooth, comfortable ride. They are geared towards
average weight small block and LS powered vehicles with stock trim. Where applicable, our handling kits offer springs that are optimized for cornering
performance while spring rates in our drag kits were chosen to maximize stored energy for weight transfer.
***What if the vehicle has been heavily modified from its original weight or has another engine? No problem. These kits are also offered without
shocks to give you the flexibility to order the shocks or struts with the spring rates you want. If you feel that you need a different shock/strut and spring rate than the one that comes with the inclusive kit please call the tech line (952-985-5675) to get the correct shock and spring rate combo for your application. Once you have the part number for the shock/strut and spring rates you need please enter it below before checkout.
