Many WJ lifts focus primarily on trail performance, but fail to take in account how the control arms and track bar will perform at their new, lifted angles in day to day driving. Rough Country's new 4-inch X-Series Suspension kit answers this age-old problem, delivering outstanding off-road action while providing an incredibly smooth highway ride. Featuring newly designed durable adjustable lower control arms with durable rubber bushings, this new kit simulates the stock angle keeping your steering components under control. This 4-inch WJ Suspension Lift also features an updated track-bar bracket, re-engineered to tie into the engine mount bolts, eliminating a common weak point and offering incredible support and rigidity. In addition this kit features a full set of N3 shocks, giving you premium vibration dampening equally suitable for off-road action or daily driving.\u003c\/p\u003e\u003ch2\u003eManufacturer features\u003c\/h2\u003e\u003cp\u003eEasy bolt-on installation Increased ground clearance Levels the front with the rear of the vehicle Lower control arms provide proper offset to allow for wider tires.
