Traxxas Revo 39T Delrin Spur Gear by 3Racing RE-031  [RE-031]

Delrin spur gear for Revo

This Delrin spur gear is a direct replacement designed for the Traxxas Revo drivetrain, intended as an RC-scale accessory for maintenance and tuning. As a Delrin (acetal) gear, it focuses on wear resistance and smooth tooth engagement compared with some softer plastics, making it suitable where consistent mesh and quieter operation are desired.

For installation, align the spur to the gearbox outputs and confirm proper mesh with the pinion gear before final assembly; small shim adjustments or repositioning of the motor mount can reduce backlash and uneven wear. Check runout and concentricity after fitting, and re-inspect after the first running session to verify there is no unusual heat or grinding.

In tuning contexts the RE-031 serves as a maintenance or replacement item rather than a performance multiplier: use it when worn teeth or chatter appear, or when swapping gear ratios for drivetrain setup. Keep lubrication and bearing condition under review so the Delrin spur can deliver consistent engagement without accelerated wear on mating metal components.
