HPI Savage 21 Titanium Main Gear

This GPM TSAV1053T main gear is a scale RC replacement part specified for the HPI Savage 21 platform. The 53-tooth spur gear is machined in titanium to provide increased wear resistance and stiffness compared with typical steel or plastic replacements. It is supplied as a single piece suitable for replacing a worn or damaged main spur on Savage 21 drivetrains.

The component is intended for use in RC-scale drivetrain assemblies only and is described here in the context of model maintenance and tuning. When fitting the gear, confirm correct mesh with the pinion gear and inspect related drivetrain parts such as bearings and the spur carrier for wear before final installation. Proper mesh and endplay adjustments help maintain consistent engagement and reduce premature wear on mating gears.

The part serves a practical role in drivetrain tuning where a firmer spur gear material can stabilise gear engagement under increased loads or after drivetrain modifications. It is compatible with the Savage 21 spur position and is offered as a direct replacement option for that chassis.

Use this titanium 53T spur gear where increased durability and stiffer gear engagement are desired during routine maintenance or drivetrain tuning on Savage 21 models; inspect gear mesh and surrounding components when installing to ensure reliable operation.
