For the rear of 65-72 F-100s, QA1 engineered a unique torque arm design that maximizes performance without the inherent binding issues of other systems, all while achieving a 4" to 7" drop. This bolt-in system also offers unprecedented adjustability: the panhard bar, torque arm, trailing arms, bracket mounts, and shocks are all adjustable, and they are truly independent of each other, so your customers don't have to worry about one adjustment affecting another. Everything you need is included, all the way down to the hardware. All components included in these systems are proudly made in QA1's Lakeville, Minnesota facility. All QA1 shocks are 100% dyno tested and serialized.
