Double Triangulated Rear 4-Link Suspension Kit (No Links, Standard)


After years of beating on this kit running through the Hammers in Johnson Valley-- some of the toughest off-road terrain on the planet!-- this suspension has proven to be the best money can buy for any Off Road Jeep.

This is the same kit we use on the Genesis MOD Class TJ Ultra4 car, and in Tony's red Jeep to pre-run for KOH. Our DOUBLE Triangulated 4 link rear suspension "builders" kit for those who want the best off-road performance.

We have figured out all the mounting points for proper geometry (weight transfer, rear steer and minimal anti-squat, etc.) to make your rig a top notch crawler with awesome articulation AND handle great on the street too!

This kit features a completely new cross member that the upper and lower control arms mount to on the frame. The kit is designed to attach behind your transfer case skid plate.

This rear kit is also perfect for moving your rear axle back, stretching your wheelbase to the Magic 100"+ when used with our EXT or COMP gas tanks.

For you guys converting from leaf springs, you can say goodbye to axle wrap and all the issues associated with it! It will be power to the ground and high clearance from now on.


  • Each mount is cut at an angle to keep the Johnny Joints in a "neutral" position so they do not waste any of the joints rotation and cause damage to the joint in those CRAZY articulation spots on the trail.
  • Kit can be used with coilover shocks or your existing coil springs.
  • Double triangulated 4 link design is the ultimate off-road.
  • The mounts in this kit are universal and can be cut or trimmed to be mounted on any Jeep TJ or YJ.
  • The frame side control arm brackets (Cross Member) are pre-welded and is to be welded permanatly into place on the frame. The mounts DO NOT tie into the transfer case skid plate. However, the corss member does obstruct access to the transfer case for removal.
  • Can be used with 14" travel shocks and is ideal for running bigger tires.


  • Heavy Duty 1/4 & 3/16" thick laser cut and CNC bent cross member.
  • Laser cut upper and lower control arm mounts for the axle.
  • 2" x .250 thick wall DOM tubing for the lower control arms.
  • 1-3/4" x .120 thick wall DOM tubing for the upper control arms.
  • Left and right hand machined bungs to weldinto the end of each control arm tube to make adjustments easy!
  • Genuine Currie forged 1-1/4" shank Johnny Joints, at both ends of the control arm for easy adjustment! (which are greasable & rebuildable)


  • This kit is only recommended for Jeeps that are driven 80% or more off-road (trailer queens)!
  • What makes it great off road, makes it more unstable on the road. This can be compensated for with a sway bar, but that limits suspension articulation.
  • Requires a 1" body and engine lift.
  • Will not work with Atlas 4 Speed transfer cases (just to big).

    Double Triangulation give you even more predictability on the trail because that rearend just follows the front axle so well. Suspension geometry, good or bad, can make or break your wheeling experience, so having Double Triangulation (which is perfect geometry) makes picking that right line easier.
