Savage 21 Aftermarket 44T Delrin First Gear Replacement DSAV1644T1T by GPM  [DSAV1644T1T]

Aftermarket Delrin first gear for Savage 21

This is a Delrin 44-tooth replacement first gear intended for the HPI Savage 21 two-speed gearbox, supplied as 1 pcs. It fits as a direct spare for the factory two-speed assembly and is useful for routine drivetrain maintenance and setup work.

Delrin offers reduced friction against metal gears which can lower wear in the first gear position. Installers should verify gear mesh, endplay and that the two-speed selector dog engages cleanly before returning the model to regular use.

Installation checklist: remove the gearbox cover following Savage 21 service steps, swap the 44T first gear while preserving shim and bearing order, then check differential and spur/pinion alignment. Carry out a slow test run to confirm shifting and re-inspect mesh after an initial break-in.
