- 2004 to 2006 Jeep LJ Wrangler Unlimited and Rubicon Unlimited
Our LJ 5.5 X-Factor Stretch Suspension Systems feature our revolutionary independent 3 link front end with track bar. This design dominates the professional world of rock crawling while also maintaining perfect streetabiliy and precise handling. The upper control arm is full length so caster change is kept to a minimum. The front upper bushing in the differential is replaced with a build a ball joint for maximum articulation.
The rear end features a triangulated 4 link assembly that allows removal of the rear track bar for awesome articulation. The rear 4 links push the rear axle back providing you with approximately 102" wheel base. The lower control arms feature a high clearance design to maximize ground clearance and cross over angles. The lower control arms are made of 2" solid alloy steel and use a Monster Bushing at the frame connection and Monster Krawler Joint at the axle connection.
Our modular skid plate design actually clam shells the frame top and bottom with no side drilling required. This adds structure to that frame! With the 3 piece construction; servicing of the driveline is a snap and does not involve any suspension modifications. The frame rail members can be bolted in or welded on. For added rear axle structure a weld in cradle and tie in plate made from thick laser cut steel is used.
