Engineered front king pins for TRX4 C hubs

This king pin set is specified to control front knuckle and hub movement on TRAXXAS TRX4 Trail Crawler front C hub assemblies. The stainless steel pins are engineered for consistent tolerance and durability, reducing play and improving steering feedback during precision crawling.

Provided as a set of four pins for the front C hub layout used on TRX4 models, the smooth pin profile reduces internal friction within the hub assembly to maintain repeatable steering geometry under load.

Installation procedure: remove the front C hub assembly to access the original king pins, replace with the TRX4004S stainless pins in the knuckle and hub bores, then reassemble and inspect for free rotation and minimal axial play. Verify fit against your specific hub components before final assembly.

Functional role: a straightforward upgrade to tighten knuckle-to-hub tolerance and minimise unwanted movement at the pivot, aiding precise low-speed steering control on technical courses.

What parts are included with TRX4004S?

Four stainless steel king pins intended for front C hub use on TRAXXAS TRX4 Trail Crawler models.

How do these pins affect hub friction and steering feel?

The polished pin profile reduces internal binding, which helps keep steering inputs consistent and reduces perceived slop at low speeds.

Any special fitment checks recommended?

Measure hub bore and knuckle clearance, confirm pin length and head seating, and verify there is no axial play after reassembly before trail use.
