4.0-in Ultimate SRS® Suspension System
The Full-Traction 4.0-in "Ultimate" suspension system for Jeep Rubicon & Unlimited is the evolution of "short arm" systems available. This new advanced system provides adjustable 4-link front axle mounting for a true and correct caster curve throughout the entire range of linear axle travel. Lower control arms feature SRS® Torsion rubber bushings & chromoly teflon lined heim joints sealed inside an ultra tough housing. No lubrication maintenance required.
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 incredible linear wheel travel and axle articulation, 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 BETTER than stock.
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 TJ Wrangler.
* Requires Retrofit exhaust kit. Full-Traction Part Number: FTS750752
