Rough Country's 4in Long Arm Upgrade Kit will turn your 4in kit into a complete long arm rig. This amazing modification transforms your Rough Country 4in regular or 4in X-series kit into a 4-link Long Arm suspension system that is incredibly capable.

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 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 1/4in thick high tensile strength plate steel.

Rough Country’s 4in kit boasts an easier install process than most long arm kits, with no welding and no removal of the factory crossmember 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!
