4-inch Suspension Lift System

Looking for uncompromised performance on and off-road? The 4-inch N2-Series Kit for Jeep YJ 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 leaf springs are included in this kit along with a power steering pitman arm and brake line relocation bracket. The 4-inch N2-Series kit also includes a tubular transfer case drop kit to maintain proper drive shaft angles as well as track bar drop brackets, bumpstops, and a full set of sway bar links. Most notably this kit is outfitted with the all-new N2.0 shocks, nitrogen charged and specifically tested and tuned for YJ applications. This allows for a super smooth highway ride and outstanding control in rugged off road situations from the same shock.
