Savage 21 First Gear 44T Delrin Low-Friction Upgrade DSAV1644T1T by GPM  [DSAV1644T1T]

44T Delrin first gear for Savage 21

This item is a Delrin 44-tooth first gear made for the HPI Savage 21 two-speed gearbox, supplied as 1 pcs. It is offered as a direct-fit spare suitable for routine maintenance or gearbox tuning tasks on scale RC models.

Delrin reduces wear against metal mating gears and is ideal where lower friction is preferred. When fitting the new gear, check gear mesh and axial endplay, and confirm that the two-speed dog engages and disengages smoothly before completing the rebuild.

Fitment hints: follow your Savage 21 gearbox removal procedure, keep shims and bearings in the correct order when swapping the 44T gear, and verify spur and pinion alignment. Test-run the vehicle slowly to verify shifting, then inspect mesh again after a short break-in run.
