Transform your 4" kit into a full-fledged long arm setup with Rough Country’s 4" Long Arm Upgrade Kit. This incredible upgrade converts your Rough Country 4" standard or 4" X-series kit into an extremely capable 4-link Long Arm suspension design.
This upgrade gives your Jeep incredible flex and unbelievable clearance at a fraction of the cost of buying an entirely new kit. The 4-link setup includes a full set of front and rear upper and lower adjustable control arms giving you full control to adjust the wheelbase and pinion angle. Each arm features Rough Country’s adjustable flex joints with Clevite 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" thick high tensile strength plate steel.
Rough Country’s 4" kit boasts an easier install process than most long arm kits, with no welding and no removal of the factory cross-member required for installation. The kit also includes extended stainless steel brake lines and coil correction plates making it that much faster and easier to install. Includes a Lifetime Replacement Guarantee!
