Is a panhard bar the same as a track bar?
Yes. Panhard bar, track bar and rear axle locating bar all describe this part.
Do I need this if I have not lifted the truck?
At stock ride height the factory bar centers the axle correctly. The adjustable bar earns its place once you change ride height — springs, spacers or a full lift.
Will I hear it in the cab?
More than with the Johnny Joint version. A heim joint has no urethane liner, so it transmits what it picks up. That is the same reason it locates the axle more precisely.
Why all the stainless hardware?
17-4 stainless spacers at both ends resist corrosion at the pivots without giving up strength, which is what keeps the joint working freely over time.
What is the tube made from?
1.5" diameter chromoly, MIG welded, with a texture black powder coat finish.
Does this fit a 2021-2024 TRX?
No. See the Fitment section above for that truck's version.
