COUPLING SHAFT

Spicer performance driveshafts are high-performance upgrades for Jeep Wrangler JL and Gladiator JT, optimized for 0"-6" lifts. They feature smaller diameters for improved exhaust clearance, direct-fit bolt-in flanges for easy installation, and thicker, high-strength steel tubing (50% thicker than OE for 1310 series front shafts, 3x0.083 DOM for 1350 series rear shafts). 1350 series driveshafts include maintenance-free SPL® 1350 Series double cardan u-joints and permanently sealed high-temperature CV boots. Some Gladiator JT rear driveshafts feature a two-piece design to address critical speed issues and optimize break-over angles.
