Traxxas Revo Delrin Spur Gear 37T by 3Racing RE-029  [RE-029]

Delrin 37T Spur Gear for Traxxas Revo

The 3Racing RE-029 is a Delrin 37-tooth spur gear produced as a direct replacement for Traxxas Revo models. Sold as an RC-scale spare part, it serves as a straightforward swap when the original plastic or worn spur gear shows excessive wear or inconsistent meshing.

Delrin (acetal) is commonly used for spur gears because it machines cleanly and gives predictable engagement characteristics in model drivetrains. This 37T spur gear keeps the tooth count identical to the listed Revo configuration, so fitment focuses on aligning the gear face and checking pinion to spur mesh rather than changing gear ratio.

Installation is a standard spur gear replacement: remove or access the gearbox cover, remove the old spur gear assembly, fit the RE-029 onto the gearbox shaft or carrier, then verify axial position and mesh with the motor pinion. Use the vehicle’s recommended shims or adjust the pinion distance to achieve correct tooth engagement without binding.
