SPC adjustable rear pinion cam bolt kit for the Jeep Wrangler JL addresses rear pinion angle issues on stock or lifted vehicles. The cam-style bolts provide up to ±1.5° of pinion angle correction to restore driveline geometry and reduce vibration after suspension changes. Note: achieving the full adjustment requires slotted axle bracket holes; SPC recommends using a rotary file set such as part 85130 or a similar tool to slot the brackets.
