Description
Achieve the ultimate flex and articulation while retaining a smooth highway ride quality with Rough Country's 4-inch Long Arm Suspension Lift Kit.

Each arm features Rough Country’s adjustable flex joints with durable rubber bushings and is constructed out of durable heavy-wall DOM tubing for a long lifespan of flex and performance. All brackets are made of a thick 1/4-inch thick high tensile strength plate steel. Includes a Lifetime Replacement Guarantee!
