AXIAL RR10 Bomber Harden Steel #45 Differential Bevel 38T & Pinion 13T by GPM YT1338TS  [YT1338TS]

Diff bevel and pinion overview

This GPM 3pc set is a direct-fit RC-scale drivetrain replacement intended for Axial platforms, focused on the differential output and motor pinion interface. The set uses hardened steel #45 for wear resistance and a spiral tooth profile on the bevel gear to improve meshing smoothness under load.

Included parts: diff bevel gear 38T (1pc), pinion gear 13T (1pc), M4*2.5*12 screw pin (1pc). Note: the M4*2.5*12 screw pin is not suitable for the Wraith platform; when fitting to Wraith models retain the original screws supplied with that kit.

Installation notes: check gear mesh and backlash when installing into the gearbox housing, confirm pinion seating on the motor shaft, and lubricate the gear faces with an appropriate RC gear lube. Because the bevel is spiral-cut, ensure axial alignment to avoid premature wear.

Use this set when replacing worn diff bevels or upgrading durability in Axial drivetrains; verify the screw compatibility for Wraith models and set gear mesh precisely for reliable operation.
