Part #: R220-250
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.

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.
