Aluminum Rear 3-Link Kit for Jeep Wrangler Unlimited JKU 2007-2018

This kit converts the rear of a 4-door Jeep Wrangler Unlimited JKU (2007-2018) to a proper 3-link running 7075-T6 aerospace-grade aluminum lower links. Steel links on a heavy JKU add unsprung weight and need constant repainting after wet trails; these 2.25" OD aluminum lowers cut that weight dramatically while a Rock Krawler double-adjustable upper arm with 1.0" Krawler Joints locates the axle and lets you dial in pinion angle. It is built for rock crawlers and heavily built JKUs that flex hard and still see street miles.

Features

• Two 2.25" OD lower links machined from 7075-T6 aerospace-grade aluminum
• Rock Krawler double-adjustable rear upper control arm with 1.0" Krawler Joints
• Rock Krawler frame-side 3-link mount included to locate the upper link
• 1.25"-12 tpi Krawler Joints with jam nuts allow length adjustment on the vehicle
• Threaded ends make setting pinion angle and axle centering straightforward
• Aluminum shrugs off rust, so there is no repainting after muddy runs
• Directly replaces the steel links in a Rock Krawler-style rear setup

The rear 3-link geometry is specific to the 4-door JKU wheelbase and is not intended for 2-door JKs, so confirm your body style before ordering. Depending on the build, completing the conversion may also call for the JK HD Crossmember with Link Mounts and an Adjustable Truss Upper Link Mount.
