HPI Savage 21 Delrin Clutch Shoes with Springs & Shim DSAV1215X by GPM  [DSAV1215X]

Delrin clutch shoes for Savage 21 fitment

The DSAV1215X Delrin clutch shoe set is an aftermarket RC-scale replacement for the HPI Savage 21 clutch assembly, supplied as a 1pr set. It uses a Delrin contact surface combined with matched springs and a shim so you can alter engagement characteristics without changing gearbox spacing or motor mounts.

Fit this set when stock shoes show glazing or wear, or when you want a firmer, more consistent engagement while tuning acceleration and low-speed control. The Delrin compound helps reduce glazing and keeps friction stable over multiple runs, while the shim provides small, repeatable adjustments to engagement depth.

Installation is a direct swap into the Savage 21 clutch carrier using the original pins and mounting points. After fitting, verify shoe alignment and free spring movement to ensure smooth engagement and clean throttle transitions. Intended for RC-scale use only.
