Whether you're tackling tough trails or cruising through city streets, the Rough Country 4-inch Lift ensures improved performance and head-turning appeal.Innovative Design and Construction: When changing a vehicle's suspension, the key to preserving ride quality is keeping the geometry of all suspension components as close to their factory angles as possible. This suspension kit combines the use of durable steel knuckles, differential brackets, and drop cross members to reduce cv angles and simulate factory angles all while achieving new heights. Featuring a set of upper strut spacers that offer uncompromised strength and rigidity, gaining lift height is no issue. Completing the rear of this suspension kit is a set of rear blocks, shocks, and u-bolts that allow you to retain factory-like geometry. This combined setup provides enough clearance to run 35" tires without additional modifications. We didn't want to limit you to one standard kit. Rough Country's 4-inch kit is configurable with all the shock options that we offer. This allows you to choose which shock series you want! Ranging from our nitrogen-charged N3 shocks to our Vertex reservoir shocks the power to choose is in your hands.Installation: With minor cutting and a strut compressor required to install, an estimated timeframe of 8-10 hours is recommended to complete this full installation. This full kit can be installed at home and can be completed efficiently and quickly!Limited Lifetime Replacement Warranty: Rough Country's 4" Suspension Lift Kit is backed with a limited lifetime replacement warranty towards manufacturer defects.
