One 32T Delrin drive gear supplied for HPI Savage models, delivered as 1 pcs. The Delrin material provides a low friction surface for reduced noise and gentler contact against metal pinions, while the fluorescent surface aids quick visual inspection during setup and wear checks.
Fitment notes: remove or loosen the spur and pinion mesh as required, swap in the replacement drive gear, then set mesh and endplay. Reuse the OEM retaining hardware and make sure the gear seats correctly on the diff output or gearbox shaft before putting the model back under load.
Performance role: ideal for trialling mesh settings and reducing drivetrain noise in test sessions; it also helps limit wear on metal mating gears. Replace when tooth faces are rounded, cracked, or suffer significant material loss.
