HPI Savage Nitro Off Road 53-Tooth Spur Gear for Tuning and Setup - JR-CHP-SAV-039 by Jazrider  [JR-CHP-SAV-039]

Tuning impact of the 53T spur gear

This 53-tooth spur gear is listed as JR-CHP-SAV-039 and fits HPI Savage Nitro Off Road Series vehicles as a main spur replacement. Made from POM and finished black, it meshes with the pinion to move motor torque through the gearbox to the wheels.

Performance focus: altering pinion size or motor output affects final gear engagement and wear; always recheck mesh after any gearing or motor change. The part ships as a single spur gear intended to replace a worn main gear on applicable Savage models.

For tuning, aim for conservative mesh clearance to limit tooth stress; aggressive pinion increases may require stronger hardware or closer inspection intervals. This component is intended for model use only.

When tuning your Savage, use JR-CHP-SAV-039 as the replacement 53T spur and re-evaluate gear mesh after any drivetrain or motor changes.
