The 4.0-in Ultimate lift system for Grand Cherokee ZJ is the continued evolution of our premium Jeep suspensions. This new system provides adjustable 4-link front axle mounting for a true and correct caster curve throughout the entire range of linear axle travel.
Full-Traction front & rear control arms are are fully adjustable and use a hi-misalignment joint on the axle end, and a large diameter SRS rubber bushing at the frame end for maximum vibration isolation. For the rear axle, this kit goes a step farther. The axle is attached to a upper triangulated link bar using our exclusive bolt-on truss mount. The tri-link pivots on a high-misalignment, adjustable teflon lined heim joint. This eliminates the need for a rear axle track bar.
The result, is excellent linear wheel travel and axle articulation, fully adjustable pinion angle settings, and all without the binding caused by the rear track bar. Do you drive your Jeep daily? The perfect geometry our our rear triangulated link eliminates chassis yaw and adds to stability at freeway speeds. This system offers hardcore rockcrawling performance from a system that rides and steers like it should.
You want tough? All components in this system are built for maximum off road punishment. We use 1.5" x .188 wall DOM tubing for our lower trailing arm assemblies, and 1/4" plate laser crafted bracketry throughout. This is a fully bolt-on system. No welding required to install. When we say "Ultimate" we mean in every available way.
This is the most feature-laden short arm system available for your Jeep Grand Cherokee ZJ. Part: FTS7407 Fits: 1993-1998 Jeep Grand Cherokee ZJ. Fits Dana 35 Rear axle vehicles only.
