The Rough Country 4"-5" lift kit includes front knuckle adapters, differential drop brackets, front & rear crossmember brackets, bump stop brackets, front brake line brackets, rear brake line proportioning valve bracket, front sway bar drop brackets, a 4" rear block kit and 4 Hydro shocks. Shock boots sold separately. Front lift is achieved by dropping the lower control arms with crossmember drop brackets. The upper control arms remain in the factory location and new lifted cast knuckles connect the upper & lower control arms. The front diffrerential is also lowered to maintain proper CV angles. A dual steering stabilizer is highly recommended.
