Take your JK up a level or 3. Premium Rear Axle Aluminum 3-link Kit for your J For the Past 5 Years, we’ve been testing 7075 Aluminum links in the ARTECON to ensure that they could handle the abuse of both extreme, heavy duty rock crawling and normal daily driving. We’ve been pleased with how they’ve handled the rigorous abuse and how much weight is saved by using is compared to standard steel tubing.
The JK Rear Aluminum 3-Link Kit starts with our ARTEC Abuse proven 2.25 inch Outer Diameter, Aerospace grade 7075 Aluminum Lower Links and couples it with Rock Krawler Suspension’s Rear 3-link Conversion Upper Link and Bracket. The aluminum links are out-fitted with time-tested Rock Krawler brand Krawler Joints with a 1.25 inch thread and 9/16 inch hole and matching jam nuts.
These are the same joints shipped in nearly every Rock Krawler lift kit so you know they stand up to the test of time and abuse…not to mention there are millions of them on the streets. Each link is threaded with both a Right Hand thread and a Left Hand thread at opposite ends so it is easy to adjust the length for fine tuning. We’ve also included wrench flats on each end of the aluminum link so you can easily tighten your jam nuts without marring the aluminum.
From there, you can add on additional components to attach the links to the vehicle if you haven’t already purchased them previously. To do the full long arm, conversion you will need the JK Long Arm Rear LCA Frame Brackets, and the JK Rear 3-Link Bracket that attaches to a flat top truss.
This bracket replaces the OEM rear axle UCA brackets with a single center mounted bracket on top of a truss. These components are all offered separately as an add-on item since many have either already purchased some of these items, or some of these brackets are included in other kits. If you need everything, just click the check boxes next to the appropriate accessories.
We also recommend an aftermarket adjustable rear tracbar, our HD rear axle tracbar bracket, and our HD rear LCA brackets. Some of these components are already included in our JK 1 ton swap kits. If you are using one of our JK 1 Ton Swap Kits, you will need the
JK Rear 3-link bracket and it will need to be modified as shown on the product page (JK4430) To complete a full swap, simply add Springs/Shocks or Coilovers, and extended brake lines and you are dialed in!
