These UCA brackets are intended to mount on the top of our new Low Profile Front Trusses and give you the same style of control arm mounting found on Jeep JK's and TJ's. The new trusses have an etched line in the top that acts as a center-line for the joint in this kit and lets you locate it at the correct location and angle (see pic 4). Made from 1/4" thick steel and gusseted on the taller mount, these brackets are basically the same as what we've been using on our revolutionary JK and TJ 1 ton swap kits for years.
From the factory, the TJ comes with 7/16" UCA holes and most all aftermarket lifts use this size. The JK comes with 1/2" UCA holes. You may select the 1/2" hole size for a TJ but you will need to drill out the hole on your control arm bracket. Includes greaseable zerk fittings. This kit is unwelded. The joints come assembled and will need to be disassembled prior to welding. DO NOT WELD ASSEMBLED JOINTS.
