It does so while providing your Jeep with the perfect off-road ride quality for heavy-duty off-roading with highway smoothness.

Each of these arms features a heavy-wall DOM steel tubing construction and uses Rough Country's adjustable flex joints with Clevite rubber bushings. This creates a long-lasting lifespan with plenty of flex.

The custom-engineered dual-rate coils in this Rough Country Lift Kit (78650A) offer two (2) distinct levels of compression to provide maximum travel with the performance you want. Along with its nitrogen-charged remote reservoir 8-stage adjustable Vertex shocks, you can tackle any obstacle! Included brackets are made from 1/4" thick tensile strength plate steel. Its extended stainless steel brake lines and coil correction plates make for an easy installation that requires no welding or removal of the factory crossmember. This kit fits 4-door models only.

Please Note: An upgraded front and rear driveshaft is HIGHLY recommended.
