Precision Titanium 53T Main Gear for Savage 21

The TSAV1053T is a CNC-machined titanium 53-tooth main spur specified for the HPI Savage 21 platform. Manufactured to tight tolerances, the component offers improved wear resistance and greater stiffness than common steel or polymer spurs, presented as a single-piece replacement for the Savage 21 main spur position.

Intended strictly for RC drivetrain applications, the part should be fitted with careful attention to pinion mesh and bearing condition. Verify correct backlash and endplay during assembly and inspect the spur carrier and adjacent bearings for wear to preserve consistent gear engagement and prevent accelerated wear on mating components.

From a tuning perspective, the titanium construction reduces material deflection under load and can stabilise engagement in higher-power or heavily modified drivetrains, making it a practical upgrade for Savage 21 owners seeking longer-lasting spur performance.

Use this TSAV1053T titanium 53T spur where improved wear resistance and reduced deformation are required; confirm mesh, bearing condition, and carrier fitment during installation to ensure optimal drivetrain performance.

What tolerances are relevant when fitting the TSAV1053T?

Focus on pinion-to-spur backlash and concentricity of the spur on its mounting surface; small axial play and consistent radial runout are critical for long-term mesh stability.

Does titanium require different fastener torque than steel spurs?

Torque settings are dictated by the carrier and fastener specifications; avoid over-tightening which can introduce distortion. Use recommended torque for the carrier hardware and verify fitment under rotation.

What maintenance steps extend spur life?

Regularly check mesh alignment, bearing smoothness, and carrier integrity. Clean debris, apply appropriate lubrication where applicable, and replace adjacent worn parts to prevent uneven loading.
