Jeep JK Rear 8-Lug Full-Float Conversion Kit w/ Performance Rotors Non-Rubicon 30-Spline 07-18 Wrangler JK TeraFlex

TeraFlex SKU: 3043000-FNNT
Regular price


Upgrade your Dana 44 rear axle with this TeraFlex JK Rear Dana 44 8-Lug Full-Float Conversion Kit. Heavy wheels and oversized tires, high-speed impacts, and low-range twisting and binding take a toll on the factory JK rear axle shafts and wheel bearing assemblies - even with upgraded 35-spline axle shaft conversions.

The twin-bearing full-float design spreads vehicle weight evenly across the forged 4140 chromoly spindles removing vehicle weight from the axle shaft. The casehardened 4340 chromoly shafts simply transfer torque to the wheels without the load stress from the vehicle weight. The spindle accepts readily available low-cost industry standard bearings and seals.

All factory sensors are maintained and protected from the elements. Retains OEM park brakes, calipers and pads.
