The factory rear JK axle and wheel bearing assembly naturally lends itself to bent axle shafts. Heavy wheels and oversized tires, high speed impacts, low range twisting and binding take their toll on factory style axle shafts. Even an upgraded 35 spline conversion shaft is subject to these same design limitations. The solution is the TeraFlex JK rear full float conversion. By utilizing a two-wheel bearing design, vehicle weight is spread evenly across the forged 4140 chromoly spindles. Readily available industry standard bearings are oil bathed and require zero maintenance.
Because the axle shaft no longer supports any vehicle weight, the case hardened 4340 chromoly shafts simply transfer the torque without the load stresses associated with impact and vehicle weight.
All factory sensors are maintained and protected, and the OE park brakes as well as the calipers and pads are retained. A TeraFlex 13.5"; performance rotor and anchor bracket are included for increased and balanced braking.
This kit includes the TeraFlex Performance Big Rotor Kit.
Before ordering, determine if axle tube O.D. is 3” or 3.25” and wall thickness 0.5” or 3/8”.
