For the rear of 1965-1972 Ford F-100 trucks, QA1 engineered a unique torque arm design that maximizes performance without the binding issues of other systems while achieving 4 to 7 inches of drop. The bolt-in system offers broad adjustability, with the panhard bar, torque arm, trailing arms, bracket mounts, and shocks all independently adjustable. Everything needed is included down to the hardware. QA1 shocks are 100 percent dyno tested and serialized, and components are made in QA1's Lakeville, Minnesota facility.
