Gain the absolute best in off-road articulation and a host of impressive features with this all-inclusive package. There are no obstacles you can't tackle with our front and rear Y-link Suspension setup featuring HUGE adjustable 2" lower control arms and X-Flex Joints. This Dual Y-link Suspension setup with longer travel arms doesn't just prevent binding and rear-steer, it gives you unparalelled axle flex while keeping pinion angles optimized - letting you negotiate trails on your terms. Combine that power with OEM style Clevite Bushings, Sway Bar Disconnects, and our Large diameter Performance 2.2 Shocks and you've got a rig that's ready to go where most wouldn't dare. The JK Long Arm Kit is built to withstand the harshes of off-road mayhem. A beefy crossmember with frame strengthening brackets gives your JK new, stronger mounting points while a 1/4" thick steel skid plate keeps everything protected from off-road hazards. This kit also includes sway-bar disconnects, stainless steel brake lines, and and adjustable front track bar. On Automatic equipped vehicles; due to use of an oversize driveshaft from the factory and inadequate factory clearance it may be possible for the front driveshaft to come in contact with the automatic transmission pan tearing the factory boot and rubbing on the shaft. Generally this occurs during heavy articulation when front sway bar links are disconnected and longer shocks are installed. If this is found to occur, the proper procedure would be to replace the oversize factory shaft with an aftermarket smaller diameter shaft to increase clearance between the transmission and front driveshaft. Rough Country does offer this driveshaft if needed.Lower X-Flex control arms feature:
  • Massive flex joints with 2.5" diameter body and huge 1.25" threads
  • OEM style Clevite rubber bushings
  • All joints are fully rebuildable
  • Fully greasable
  • Adjustable retainer ring
  • Lower joints pivot up to 35 degrees
  • Made of 2" diameter heavy duty tubing

      Does the driveshaft clearance issue apply to manual vehicles as well?

      • The Exhaust spacer is recommended in conjunction with the Rough Country 4 in. X-Series Long Arm Suspsension Lift Kit w/ Shocks (07-17 Wrangler JK 2 Door) if your Wrangler JK is 2012 or newer. This is recommended for both automatic and manual transmissions.

          I wish!!

          Wish I would have received it, however they sent me a x-series short arm kit instead. I decided to keep the short arm kit and it is pretty amazing lift. Made my 2door jk ride so much better. Install took about 5-6 hours.

          Installed nice. Looks greats. I would highly recommend getting the dual steering stabilizers, the extended drive shafts and the calibration chip if you buy this lift.
