Heavy Duty Delrin Spur for HPI Savage 21

The GPM Delrin main gear is designed to replace the standard spur in the HPI Savage 21 with a 49-tooth profile that promotes smooth torque transfer and better resistance to wear. The Delrin material keeps friction low while offering strength for demanding driving conditions.

Reasons to Upgrade

Straight swap for HPI Savage 21 installations
Durable Delrin for reduced wear
49T configuration for predictable gear interaction
Helps maintain drivetrain integrity under load

Do I need special tools to fit this gear?

Basic hobby tools are enough: a driver for the spur nut and a feeler for mesh checks. No specialised equipment is required for installation.

Will this change my gear ratio noticeably?

If you match the factory pinion size, the 49T count is intended to maintain the original ratio while improving engagement and durability.

Is Delrin prone to cracking on impact?

Delrin is resilient and resists wear, but extreme impacts or repeated heavy shocks can still damage plastic gears; inspect after hard crashes.
