Heavy duty rear knuckle inners for TRX4

The TRX4022 rear knuckle inner set is a metal replacement for the original plastic inners on TRAXXAS TRX4 Trail Crawler axles, aimed at keeping the internal gear train steady on technical trails and rock sections.

Parts are milled from 6061 T6 aluminum and finished with CNC processes to maintain tight tolerances and consistent fit. The package includes matching stainless steel cap head screws so you have the mounting hardware needed for installation.

These inners help reduce side-to-side movement at the knuckle interface and protect gear engagement during slow, torque-heavy crawling. Always trial-fit components and check supplied screw lengths with your axle assembly before final tightening.

How do I confirm these will fit my axle?

Compare the shape and mounting holes of the TRX4022 parts to your TRX4 knuckle inners and measure screw engagement depth to be sure of fitment.

Will these change steering feel?

They make the knuckle interface firmer which can translate to crisper, more consistent gear action under load rather than a change in steering geometry.

Are the screws corrosion resistant?

The kit uses stainless steel cap head screws which provide good resistance to corrosion for normal outdoor use.

Do I need threadlocker?

A small amount of medium strength threadlocker is recommended if you run in wet or high vibration conditions, but confirm compatibility with your screw and axle materials.
