Delrin clutch shoes built for Savage 21 use

The DSAV1215X Delrin clutch shoe set is an aftermarket RC-scale replacement compatible with the HPI Savage 21 clutch assembly, supplied as a 1pr set. It features a Delrin friction surface alongside matched springs and an adjusting shim, so engagement can be tuned without moving motor or gearbox mounts.

Replace worn or glazed stock shoes with this set when you need a firmer or more predictable engagement, or when you are trying different spring rates to tune acceleration. The Delrin material resists glazing and delivers consistent friction over repeated runs, while the shim allows small changes to engagement depth.

Installation is a direct swap into the Savage 21 clutch carrier using the original pins and mounting points. After installation, confirm shoe alignment and free spring action to ensure clean engagement and release during throttle changes. Intended for RC-scale applications only.

Is this a direct fit for Savage 21?

Yes. The DSAV1215X is designed to replace the original shoes and fits the stock clutch carrier without modification.

What benefits do Delrin shoes give?

Delrin offers improved resistance to glazing and stable friction characteristics, helping engagement stay consistent across multiple runs.

How should I set the shim for track use?

Start with the shim thin setting and test throttle response on a bench. Increase spacing in small increments until the launch feel and idle slip match your setup and surface conditions.

Are these shoes suitable for tuned engines?

They are suited to higher power as long as you tune springs and shim to control engagement; always verify clearance and heat under heavy use.
