TRAXXAS Revo Main Spur Gear 39T - DTRV039T by GPM  [DTRV039T]

Delrin main spur for Revo gearboxes

This Delrin main spur is a direct replacement for TRAXXAS Revo and Revo 3.3 gearboxes, supplied as a single 39T spare to restore predictable mesh and drivetrain behaviour for routine hobby use.

The Delrin construction reduces friction and helps maintain steady tooth engagement under normal RC loads. It is a good choice when you want quieter running and a smoother feel compared with some harder spur materials.

Installation follows standard Revo gearbox service: remove the case cover, swap the factory spur for this unit, set gear mesh and backlash, then reassemble. After fitting, rotate the drivetrain by hand and complete a short low-throttle test to confirm correct engagement and to check for unusual noise.

Care and maintenance: check teeth for chips or wear before each session, keep mating gears and bearings free of grit, and avoid sustained overloading to extend service life.
