JKU Rear ALUMINUM 3-Link Kit

The JKU Rear Aluminum 3-Link Kit converts the rear of your 4-door Jeep Wrangler Unlimited to a three-link on lightweight 7075-T6 aluminum. Two oversized aluminum lower links and a Rock Krawler double-adjustable upper give you the articulation and adjustability of a proper 3-link while shedding the weight and rust worries of steel.

Key Features

• Two massive 2.25" OD 7075-T6 aluminum rear lower links for strength with minimal weight
• 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
• Rock Krawler Krawler Joints and jam nuts on the lowers for on-vehicle length adjustment
• Rust-resistant aluminum needs no repainting after wet or muddy trails
• Directly replaces steel Rock Krawler kit links for a lighter rear suspension

Fitment & Compatibility

Built for the rear of the 4-door Jeep Wrangler Unlimited JKU (2007-2018); the rear 3-link geometry is specific to the 4-door wheelbase and is not intended for the 2-door JK. Pair it with the front upgrade using the JK Front Aluminum 3-Link Kit, or step up to the full JKU Aluminum Long Arm Kit. Completing the conversion may require the JK HD Crossmember with Link Mounts and an Adjustable Truss Upper Link Mount, sold separately.

Frequently Asked Questions

Will this fit a 2-door JK?
No. The rear 3-link geometry is specific to the 4-door JKU (2007-2018).

Is this a complete rear suspension?
It is the rear 3-link link set. Depending on your build you may also need the HD Crossmember with Link Mounts and an Adjustable Truss Upper Link Mount to locate everything.

Can I run this with the front aluminum 3-link kit?
Yes. It pairs with the JK Front Aluminum 3-Link Kit for a matched, lightweight front-and-rear setup.

How adjustable is it?
The lowers thread onto Rock Krawler joints with jam nuts, and the rear upper is a double-adjustable Rock Krawler arm, so you can dial pinion angle and centering.

Why aluminum instead of steel?
The 2.25" 7075-T6 lowers deliver comparable strength at much lower weight and will not rust like steel links.
