TRX4 Differential Bevel 34T with 11T Pinion 40CR Steel Aftermarket TRX41134T by GPM  [TRX41134T]

Replacement differential bevel and pinion for TRX4

This kit supplies the internal differential bevel and matching pinion used in TRX4-based trail crawlers. Included are a 34T bevel differential gear and an 11T pinion gear fabricated from 40CR steel for use in scale RC drive systems only.

The components are positioned in the inner region of the front or rear gearbox to transfer torque from the motor output to the axle shafts. As aftermarket replacements they are intended to restore correct mesh and maintain steady power transfer under crawling conditions.

Assembly guidance: verify correct gear mesh and backlash with your existing spur and pinion prior to final assembly, remove any grit or old lubricant from the gearbox, and apply the correct RC gear grease to the teeth to reduce wear and noise.

Replace worn internal diff bevels with this 40CR steel bevel and pinion set to recover smooth, reliable low-speed drivetrain engagement in TRX4 and compatible TRX-6 gearboxes.
