Rough Country 78550A 4in Long Arm Suspension Lift Kit with Vertex Reservoir Shocks for 07-11 Jeep Wrangler Unlimited JK
Many states have laws that limit the maximum height of a lifted vehicle. Never exceed the legal height limit.
Wrangler Unlimited JK: The Rough Country 4in Long Arm Suspension Lift Kit was designed for use with four door Jeeps. The coil springs were specifically tuned for the Unlimited JK, and this kit is not compatible with two door models. Rough Country includes an exhaust spacer and a loop delete pipe for the 12-18 Wrangler Kits. This ensures there is no interference with the front driveshaft.
X-Flex Adjustable Control Arms: The Rough Country 4in Long Arm Suspension Lift Kit features fully adjustable X-Flex control arms. These fully greasable control arms feature OEM style, Clevite brand rubber bushings. The oversized flex joints have 2.5" diameter bodies and 1.25" threads, and they are rebuildable.
Run Larger Wheels and Tires: The Rough Country 4in Long Arm Suspension Lift Kit allows you to fit 35x12.50 on your four door Jeep. You will also need between 4.5” and 4.75” of backspacing, so if you are using factory wheels, then you will need 1.5” wheel spacers.
Shock Options: Select from Rough Country’s N3 shocks or Vertex Remote Reservoir shocks. N3 shocks provide smooth performance with nitrogen-charged 10-stage variable valving. Vertex shocks feature 8-stage adjustability, and a nitrogen-charged monotube design. The remote reservoir increases fluid capacity, and reduces fade by dissipating heat.
