JK Rear Frame UCA 3-link bracket

The Artec JK Rear Frame UCA 3-Link Bracket lets you run a single upper control arm above the driveshaft on a four-door Jeep Wrangler JKU — the foundation of a clean rear 3-link conversion. It is a boxed, laser-cut steel bracket that welds into the frame between the factory crossmembers and integrates a skid to protect the joint.

Key Features

• 3/16" thick boxed steel plate for strength and impact resistance
• CNC laser cut and CNC bent for precise fit, made in the USA
• Mounts a single upper control arm above the driveshaft, between the factory crossmembers
• Built-in skid plate to protect the joint from trail strikes
• Top-access grease fitting provision for easy joint maintenance
• Weld-in design for a permanent, high-strength mount

Fitment & Compatibility

Designed for the four-door Jeep Wrangler JKU (2007-2018) and requires roughly 1" of lift for clearance. It is built specifically for RockKrawler Krawler joints with a 2.325" mounting width and a 9/16" bolt hole (as used on the RockKrawler X-Factor rear 3-link upper control arm). Confirm your upper arm's joint dimensions before ordering.
