Rock Krawler is proud to bring you the LJ Triple Threat Long Arm Upgrade System. The Triple Threat Systems are the most versatile systems ever made for Wrangler LJs! These systems feature a front end design that can function as a full 4 link for high speed fun in the sand or the extremely flexy independent 3 link for extreme trail use! The best part is you get to choose! The rear end features a triangulated 4 link assembly that allows removal of the rear track bar for awesome articulation and full axle droop. All Rock Krawler upper control arms are full length! No short or mid length upper control arms with compromised geometry. Our geometry is perfect in every way. Our high clearance lower control arms are made of 2 solid alloy steel and use 1 shank Monster Krawler joints at the axle connection and the industrys largest bushing at the frame connection for the quietest ride quality out of any suspension system on the market. We have even included a new heavy duty passenger side axle mount made of 1 thick alloy steel and 2 build a ball joints for the upper control arm pivots at the axle. No need to worry about wearing out the stock front upper control arm axle bushings since they have been replaced! Our unique 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 easy and does not involve any suspension modifications. The frame rail members can be bolted in or welded on, yet again, it is your choice! The Rock Krawler weld on rear cradle and tie in plate ads a tremendous amount of structure to the rear axle housing making it bullet proof! Simply put, we feel this is the strongest, most versatile and most capable Long Arm Upgrade system ever made. Rock Krawler also backs that up with our Abuse Proof Lifetime Guarantee on all hard parts!
