Product summary

This replacement set contains a 33T differential bevel gear and a 12T pinion gear made from 40CR steel, specified as an RC-scale drivetrain spare for TRAXXAS TRX4-series crawlers and compatible TRX6 platforms. The pair installs inside the front or rear gearbox to transfer torque through the differential assembly.

Swap this set in when alloy or plastic gears show wear or when you need a direct gearbox replacement. 40CR steel is selected for a balance of toughness and wear resistance appropriate for typical trail crawling loads; check gear mesh and bearing condition during fitting to avoid early wear.

Installation notes: remove the gearbox cover, keep original shims and bearings in their positions, fit the bevel and pinion in their original orientation, then verify backlash and smooth rotation before final sealing. This component is for model use only.

Packing includes

  • Diff bevel gear - 1pcs
  • Pinion gear - 1pcs

This gear set is a direct-fit drivetrain spare for TRAXXAS TRX4 and TRX6 platforms, useful for gearbox replacement and routine tuning to restore reliable power transfer in scale trail crawlers.

Will this fit both front and rear diffs on TRX4 models?

Yes, the bevel and pinion are sized to sit in either the front or rear gearbox on the listed TRX4/TRX6 variants but always confirm dimensions against your chassis before final assembly.

Is 40CR steel a good upgrade over stock gears?

40CR offers improved toughness and wear resistance compared with standard alloy or nylon gears, making it suitable for trail crawling where loads and impacts are common.

Do I need new bearings when fitting this set?

Inspect existing bearings for smooth spin and play; replace any that are worn to ensure correct gear mesh and to prevent premature gear wear.

What prep should I do before sealing the gearbox?

Set backlash, confirm smooth rotation across the range of motion, and recheck shim positions before applying threadlocker or sealant to avoid trapped misalignment.
