The Carli Front end Upgrade Kit was designed to address these problem areas with replacements that are robust, serviceable alternatives purpose built to solidify your front end. Whether on stock suspension and tires or 37″ Mud Terrains with a fully-equipped Carli System, the Front End Upgrade Kit will put front end issues in your rear-view. Overwhelmingly, the most frequent cause of front end “play” and front-end instability is the factory track bar. The track bar is the lateral link that determines the front axle's tracking relative to the frame rail while the control arms/radius arms control the axle's movement fore & aft. The factory-installed track bar has vulcanized rubber bushings on both ends. A vulcanized (clevite) bushing is a non-modular assembly where the damping/isolation material is bonded to an inner and outer sleeve, then pressed into the housing. There's no slip in this joint. Every movement of the axle puts a torsional, fatiguing load on the material stressing and eventually, tearing the functional portion of the bushing assembly. Our goal, develop an adjustable link to center the axle on leveled/lifted Rams that sharpens steering input, deflects less than the stock bar, and dampens vibrations to numb the wheel and extend the life of the serviceable ends all while avoiding excess deflection and the sloppy handling associated with the stock bar. Our Adjustable Track Bar is constructed from 1.5″ OD, 3/8″ wall tube making it far stronger than the brackets to which it's bolted and features a 7/8″ FK Bearing chromoly race heim joint at the axle end locked in place by our proprietary JAMMIT nut with 100% more surface area than a standard Jam Nut.
