Jeep Wrangler Unlimited 4 door JKU Double Triangulated 4-Link Rear Long Arm Upgrade. We set out 2 years ago to design a double triangulation for the JKU that solved many challenges and restrictions with the JK platform.

We gave up a small amount of belly height (not a flat belly) to achieve better anti-squat and roll center numbers. The results were incredible and if our recommended rear Axle separation is used a 94 anti-squat can be achieved on a JKU. There is no need to remove the body for installation.

Kit includes:

• Upgrade to 2.25 (includes all lowers)
• Rear weld in laser cut crossmember with lower link mounts
• Rear weld in upper link frame side mounts
• Truss top 4-link mounts (truss Not included)
• Axle side lower control arm mounts
• (2) 1.75 Inch Solid 7075 T6 Aluminum links with narrow Rock Jock Johnny Joints
• (2) 2 Inch Solid 7075 T6 Aluminum links with narrow Rock Jock Johnny Joints
• (1) Skid Plate in 1/4 Inch laser cut and CNC broke smooth bottom
• Includes all grade 8/10.9 hardware

This kit requires:

• An exhaust modification moving the Y link behind the cross member (2012+ both Magnaflow and AEM make bolt-in Y pipe kits)
• Drilling one hole and welding a third link mount on the Axle or truss
• The side JKU factory fuel tank be removed
• Outboard coil overs
• Rear Axle to have a truss
• Our skid plate can be modified to work with other front crossmembers (call for details)
• Evaporative canister will need to be relocated
• Exhaust will need to be customized
