2007-18 Jeep Wrangler Unlimited 4" Long Arm Upgrade Kit

If you’re ready for some serious off-roading, install the Rough Country long arm upgrade kit on your Jeep Wrangler JK with a 4" lift kit. This 4-link system was designed to provide incredible, jaw-dropping off-road performance without sacrificing the Wrangler’s lush highway ride quality. By maintaining suspension geometry as near to factory angles as possible, the result is a more capable and freer setup.

A set of both front and rear upper and lower adjustable control arms provide the ability to adjust the wheelbase and pinion angle. The arms are constructed using durable heavy-duty DOM tubing with adjustable Flex joints with Clevite rubber bushings for a long lifespan of performance. ¼” thick high tensile strength plate steel is used to construct the brackets. The flex joints are fully greasable and rebuildable and feature a massive 2.5" diameter body and 1.25" thread.

Installation is easier than most long arm lifts. No welding or removal of the factory crossmember is required. Included in the Rough Country 4” long arm upgrade kit for the Jeep Wrangler JK Unlimited are:

· Front and rear upper and lower adjustable control arms with flex joints
· Exhaust spacer
· Frame strengthening brackets
· Sway-bar quick disconnects
· Forged adjustable track bar
