Savage 21 44T Delrin First Gear Low-Wear Replacement DSAV1644T1T by GPM  [DSAV1644T1T]

Delrin first gear for Savage 21 two-speed gearbox

This replacement first gear is a Delrin 44T unit made 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 presented here for practical RC drivetrain upkeep and tuning.

Choose this Delrin gear when you want a lower-wear option in the first-gear position or a like-for-like swap after wear or damage to the OEM part. Delrin runs with lower friction against metal mating gears, so during reassembly verify gear mesh and endplay and ensure the two-speed dog engages cleanly.

Installation notes: remove the gearbox cover following your Savage 21 service steps, replace the 44T first gear while keeping track of shims and bearings, then check differential and spur/pinion alignment before final torque. Run the model slowly to confirm shifting, then re-check gear mesh after a short break-in period.
