RockJock 4x4 Johnny Joint Uni-Ball for 3-Links. Fits JL and JT Factory Diffs (only). Incl. Installation Tool - RJ-301002-101

RockJock Uni-Balls for Front Axle Housings are used in 3-link suspension applications, where the passenger's side upper control arm has been eliminated and all of the suspension load is now being applied to the one axle housing mounting location.

Our Uni-Balls press into the stock bushing holes on the casting side, driver's side ONLY) of the front differential housing and provide a durable solution that incorporates a 5/8 inch thru-bolt hole for heavier hardware.

This Uni-Ball will press into a stock JL or JT housing, only). The mounting width of the center pivoting assembly is 2 inch, to allow it to fit into the fork on JL/JT front upper control arm, however, the 5/8 inch thru-bolt hole will require drilling of the bolt hole in the control arm fork.

Uni-Balls feature a sealed bearing assembly, so no greasing is required. Finish is clear zinc plating.
