Tuning impact of the 52-tooth spur on Savage drivetrains

This 52T spur is a direct-replacement main gear intended for HPI Savage Nitro Off Road Series models. Built from POM, the gear matches the factory tooth count and suits the main gear location in Savage drivetrains.

The spur transmits torque from the motor pinion into the gearbox and rear driveline. When swapping spurs, confirm tooth count and material compatibility with existing components, set correct pinion mesh, and check bearings and mounting hardware for wear or play.

Installation guidance: follow the Savage chassis procedure to remove the slipper or spur carrier, orient and fit the gear, adjust mesh to the manufacturer recommended clearance, and check for free rotation before running. Proper cleanliness and tooling will reduce the risk of misfit or premature wear.

Use this POM 52T spur when maintaining or tuning HPI Savage gear ratios, and always reconfirm mesh and drivetrain support components after installation.

How does this 52T spur affect top speed and acceleration?

Using the stock 52T keeps the existing ratio intact; changing spur size alters final drive and will require pinion adjustments to reach desired speed or acceleration characteristics.

Should I change pinion when fitting this spur?

If you keep the 52T spur, a pinion change is not necessary for ratio preservation; if you change teeth count, recalculate pinion size and verify mesh before running.

Will mesh settings need adjustment after installation?

Yes. Always set the pinion-to-spur mesh to the chassis manufacturer's recommended clearance and validate free rotation under hand prior to powering the model.

Can this spur be used for aggressive tuning runs?

POM is suitable for standard tuning; for extreme power setups consider monitoring wear more frequently and inspect for tooth deformity after high-stress sessions.

Tips for balancing performance and durability?

Maintain correct mesh, ensure bearings and pinion are in good condition, and avoid unnecessary impacts to balance performance gains with gear longevity.
