The JK Front Aluminum 3-Link Kit converts the front of your Jeep Wrangler JK to a three-link built around lightweight 7075-T6 aerospace-grade aluminum. Two oversized aluminum lower links and a single aluminum upper give you a strong, adjustable front suspension that saves weight over steel and shrugs off rust and trail abuse.
Key Features
- Two massive 2.25" OD 7075-T6 aluminum lower links for high strength at low weight
- Single 2.0" OD 7075-T6 aluminum upper link to complete the front three-link
- Rock Krawler Krawler Joints with wrench flats and matching jam nuts for on-vehicle adjustment
- Threaded ends make it easy to set caster and axle centering during setup
- Rust-resistant aluminum removes the need to repaint links after wet trails
- Directly replaces steel Rock Krawler kit links for a lighter, more capable front end
Fitment & Compatibility
Designed for the front of the Jeep Wrangler JK and 4-door JKU (2007-2018). Pair it with the JKU Rear Aluminum 3-Link Kit for a matched front-and-rear build.

Frequently Asked Questions
Which Jeeps does this fit?
The front of the 2007-2018 Jeep Wrangler JK and 4-door JKU.
Is this a full front suspension?
It is the front 3-link link set. A complete conversion also needs the HD Crossmember with Link Mounts, the Front 3-Link Frame Mount Bracket, and an Adjustable Truss Upper Link Mount.
Can I run it with the rear 3-link kit?
Yes. It is designed to pair with the JKU Rear Aluminum 3-Link Kit for a matched lightweight setup.
How do I set caster?
All ends are threaded with jam nuts, so you adjust the link lengths on the vehicle and verify alignment before final torque.
Do aluminum links survive rock crawling?
Yes. The 7075-T6 links are tested for years of extreme crawling and daily driving while cutting weight versus steel.
