Who says your daily driver and your weekend warrior can't be the same vehicle? The 4" N2-Series Kit for Jeep TJ was engineered by Rough Country's Research and Development Team to give the perfect blend of off-road performance and smooth highway ride. A set of application tuned, lifted coil springs are included in this kit along with a set of tubular lower control arms outfitted with rubber Clevite bushings for the best in vibration dampening. The 4" N2-Series kit also includes a tubular transfer case drop kit, track bar bracket; and a full set of extended sway bar links. Most notably this kit is outfitted with the all-new N2.0 Shock Absorbers, nitrogen charged and specifically tested and tuned for TJ applications. This allows for a super smooth highway ride and outstanding control in rugged off road situations from the same shock.
