Axial Racing EXO Replacement Delrin Spur 48T DEX048T by GPM  [DEX048T]

48-tooth Delrin spur for EXO drivetrains

This Delrin 48T spur is supplied as a single replacement part for use on the Axial Racing EXO platform. Delrin material reduces friction and lowers gear noise compared with many metal spurs, and the component is intended for hobbyist tuning and routine maintenance on electric drivetrains.

Fitting advice: confirm pinion-to-spur mesh and set backlash before first use, employ shims or motor mount adjustments to dial in a smooth engagement, and ensure the pinion tooth count pairs with the 48T spur for the gearing you want. Avoid over-tightening the hub fasteners to prevent hub compression; re-evaluate alignment after an initial brief run under load.

Tuning notes: the 48T spur alters the drivetrain ratio, so combining it with different pinion sizes will change acceleration and top speed. Change one parameter at a time and record the results to refine settings for trail riding, rock crawling or casual bashing.
