Synergy Manufacturing Rear 4-Link Kit for 87-06 Jeep Wrangler & Wrangler Unlimited YJ/TJ

The kit is ideal for enthusiasts wanting to put after-market axles under their Jeeps because of all the axle brackets included in the kit. Optional differential truss kits are available for specific applications.

All the brackets are designed and built using the latest CAD solid modeling software and CNC laser cutting & bending processes. The kit feature tried and true Johnny Joint bearing assemblies at all the suspension pivoting points. The main frame control arm mounts are pre-welded to a "C" section of steel to beef up the frame and help distribute the load. You simply slip each mount over the frame and weld them in place.

Our kit can be used with coilovers or coil springs and shocks. The triangulated 4 link design eliminates the rear track bar; this makes for a very clean installation on your jeep.
