The track bar is the most important link under the front end of a straight axle, heavy-duty truck. It’s both a suspension and steering component and any deflection in the bar or wear in the bushings are immediately felt by the driver in the form of excessive steering input, floating front end, wandering, and last but certainly not least, the dreaded death wobble. Exacerbate the bar’s susceptibility to the above by lifting the truck and increasing the load while pulling the axle off-center and so completes the recipe for disaster.
Enter the Carli Adjustable Track Bar. The goal, a link that deflects less than the stock bar, dampens vibrations without causing the sloppy handling associated with the stock bar, ensure service life far in excess of a factory unit while being rebuildable (vs. replaceable like the factory bar) all while being adjustable to center the axle on leveled vehicles. Many years have seen many iterations but we’ve landed on a design we feel impervious to future improvement
The DATB Track Bars are 3/8″ wall DOM construction, FAR stronger than the brackets to which they’re bolted. This wall-thickness allows the end of the bar to be threaded to accept our 1″ x 7/8″ FK Bearing Chromoly RSMX14T Heim Joint with a massive 1″ shank.
You’ll see many manufacturers running thinner wall and weld-in bungs with 3/4″ or 7/8″ shank heims as our previous generations did; running the thicker wall bar allows for more strength and one less welded joint – a potential point of failure – and the larger shank for exponentially more shear strength.
In place of a standard Jam-Nut, we’ve developed a tapered Jam Nut (mating surface similar to a lug nut) and matching machined taper into the end of the track bar. This ensures perfect centering of the joint while providing 100% more friction surface area than a standard Jam-Nut. More surface area equals more clamping force and a more reliable assembly.
The frame end of the track bar saw a massive improvement in the DATB generation, as well. Our “CUB” joint starts with a proven FK Bearing 7/8″ Uniball at its center. Custom molded bushings are pressed on to encapsulate this Uniball then the assembly is pressed into the huge, gusseted frame-end housing of the track bar with a Stainless safety washer and retained with a snap ring. Custom Misalignment spacers center the joint in frame bracket and ensure full fore and aft movement of the track bar to be possible without bind or excessive bushing deflection.
