The RE-027 35-tooth Delrin spur is a direct-fit aftermarket component intended for Traxxas Revo drivetrains. It transmits rotational input from the pinion to the drivetrain without altering electrical systems. The Delrin resin provides a balance of wear resistance and reduced sliding friction compared with basic thermoplastics, suitable for routine replacement and minor ratio adjustments.
Installation requires gearbox access and a standard mechanical swap: remove the existing spur from the shaft, inspect pinion and bearing condition, validate mesh alignment, then install the 35T spur ensuring concentric seating and correct backlash. Confirm the tooth count and mounting interface for your chassis variant prior to fitment to ensure correct engagement and load distribution.
In setup terms, the 35T tooth count modifies the final drive ratio relative to your current spur and pinion pair. Use this spur to fine-tune acceleration versus top speed, and monitor mesh, axial play and preload to protect the drivetrain from premature wear.
