Aftermarket Delrin 37T Spur for Revo

The RE-029 is a 37-tooth Delrin spur supplied as a direct replacement for Traxxas Revo gearboxes. It replaces worn plastic spurs to help restore smooth, reliable meshing in the drive train.

Delrin (acetal) is a typical material for spur gears thanks to clean machining characteristics and consistent engagement under model loads. Retaining the 37T tooth count preserves the original gear ratio so the focus during fitment is on axial alignment and pinion mesh.

Installation is standard: open the gearbox, remove the existing spur assembly, locate the RE-029 on the carrier or shaft, then verify axial position and set pinion spacing. Use existing shims or fine tune the motor distance to avoid binding while maintaining correct engagement.

Will the RE-029 alter my gear ratio?

No. The 37-tooth count is the same as the listed Revo configuration, so swapping to this spur does not change the ratio when fitted in the same position.

Any tips for achieving correct mesh?

Set the spur axial position first, then adjust pinion distance or shims while rotating the drivetrain to ensure smooth, even tooth contact without tight spots.

Is Delrin a good choice for scale use?

Yes. For scale and general basher use Delrin provides consistent performance; monitor wear for high-power applications and consider metal options only if required.
