Precision rear knuckle inners for TRX4 crawlers

The TRX4022 rear knuckle inner set is a metal replacement tailored for TRAXXAS TRX4 Trail Crawler axles, intended to keep the internal gear set steady during rock crawling and slow technical manoeuvres.

Manufactured from 6061 T6 aluminum and finished with CNC machining, these inners deliver consistent fits and surfaces. The kit includes stainless steel cap head screws so you receive the mounting hardware required for installation.

Designed to reduce lateral movement at the knuckle junction, the parts help maintain proper gear mesh under load and extend the life of the driven components. Confirm screw length and clearance during trial assembly before final torqueing.

Will these fit my TRX4 axle housings?

They are designed for TRAXXAS TRX4 Trail Crawler knuckles; compare bolt pattern and geometry to your axle before committing to fitment.

Should I replace the screws with something stronger?

The supplied stainless steel cap head screws are appropriate for typical use, but some builders opt for grade-matched hardware if running extreme setups.

Do these require any modifications?

No machining should be required; parts are designed to bolt into the existing knuckle assembly, though you should check clearances and thread engagement during test fit.

How do I prevent galvanic corrosion?

Keep mating surfaces clean and consider using compatible fastener materials; stainless screws help minimise corrosion risk but regular inspection is advised.
