You're building your truck for a purpose, paying attention to every detail, every connection, and every movement. We built our system this way, too. With this all-new, engineered-from-scratch system, you can stop using junkyard parts to modernize your pickup and can bolt in the handling and performance you've always wanted. Designed specifically for your 1975-1979 Ford F-150, the front system is 3.75" narrower than a Crown Vic, providing ideal handling and allowing fitment of larger wheels and tires. The system also saves 150 lbs. of weight and provides 3" to 5" of drop with standard spindles and 5" to 7" with drop spindles. Everything you need is included, all the way down to the hardware.

In addition to double- or single-Adjustable Shocks and High Travel Springs, you get upper and lower Control Arms, upper and lower crossmembers, rack and pinion steering, and stock or drop spindles. All components included in these systems are proudly made in QA1's Lakeville, Minnesota facility. All QA1'shocks are 100% dyno tested and serialized.
