TJ Front Axle UCA replacement

The factory upper control arm bracket on the passenger side of the front axle is one of the weakest points on a Jeep TJ, LJ, XJ, MJ or ZJ — it is a thin stamping that bends and tears under hard wheeling. This Artec UCA replacement bracket is cut from 1/4 in. steel and fully gusseted so it will outlast the vehicle and take the guesswork out of your front suspension mounting.

Key Features

• Cut from 1/4 in. thick steel — far stronger than the factory stamped bracket
• Gusseted construction to resist bending and tearing on the trail
• Direct replacement for the passenger-side front upper control arm mount
• Weld-on design that reinforces a known factory failure point
• Compatible with common upper-joint choices for a clean rebuild

Fitment & Compatibility

Fits the passenger-side front axle upper control arm location on the Jeep TJ, LJ, XJ, MJ and ZJ. It is a weld-on bracket and works with either a Daystar bushing or an upgraded Johnny Joint for the upper arm. If you are refreshing the whole front axle, also look at the Coil Bracket Replacement for TJ/LJ/XJ/ZJ front axles.

Frequently Asked Questions

Which Jeeps does this bracket fit?
It replaces the passenger-side front upper control arm bracket on the Jeep TJ, LJ, XJ, MJ and ZJ.

Does it require welding?
Yes. You will cut off or grind down the failed factory bracket and weld this reinforced 1/4 in. bracket in its place. Confirm your control-arm angle before final welding.

What upper joint does it use?
The bracket is built to accept a Daystar bushing or a Johnny Joint upper, so you can match it to how you are building the rest of the front suspension.

Why replace the factory bracket?
The stamped factory mount is thin and prone to bending or ripping under bigger tires and hard flex. The 1/4 in. gusseted replacement removes that failure point.
