ROUGH COUNTRY LONG ARM UPGRADE KIT 4" | Jeep Grand Cherokee ZJ

The Rough Country Long Arm Upgrade Kit is the definitive upgrade for your Jeep Grand Cherokee ZJ 4WD (1993-1998) running 4 inches of lift. When you lift your ZJ, the factory short arms work at steep angles, causing vibrations, premature wear and poor off-road behavior. This kit fixes it.

• Reinforced long arms that correct suspension geometry after a 4" lift.
• Improves axle articulation and traction on broken terrain.
• Restores on-road comfort, eliminating vibrations and harshness typical of short arms.
• Heavy-duty construction built for intensive off-road use.
• Includes frame brackets and all necessary hardware for installation.

Installation requires mechanical knowledge, welding on some brackets and proper tools. We recommend a specialized workshop. Once installed, you'll feel a much more stable, comfortable and capable ZJ, both off-road and on tarmac. A must-have upgrade if you want to get the most out of your lifted suspension without giving up daily driving.
