Precision titanium universal main shaft for Savage

This titanium universal main shaft is provided as an RC replacement component for the HPI Savage platforms named in the product title. It functions as the central rotating member in the drivetrain assembly, offering a corrosion-resistant solution while maintaining the same key dimensions used by the listed Savage variants.

The shaft transmits torque through the gearbox and differentials in Savage drivetrains. During replacement, verify bearing seating and axial alignment, then check spur and pinion mesh and endplay after reassembly. The component is supplied as a single universal shaft designed to match the vehicle architectures referenced in the product title.

For tuning and workshop use prefer this shaft where titanium's stiffness-to-weight ratio and surface corrosion resistance are required. Confirm chassis layout and exact part dimensions before assuming fitment on any variant not explicitly listed.

Compatible Models

  • HPI Savage
  • Savage X
  • Savage Fluorescent

Install this shaft to replace the original main shaft on the listed HPI Savage variants to preserve drivetrain geometry while upgrading to a titanium component; inspect bearings, couplings and gear mesh as part of the installation process.

What checks ensure correct fit of TSAV1037?

Measure bearing inner diameters and shaft locations, confirm axial length and coupling clearances, then trial-fit the shaft before full assembly to verify alignment and mesh.

Recommended workshop procedure for replacement?

Support the gearbox, remove housings carefully, note bearing orientation, replace the shaft, then reassemble and run a slow rotation check for binding and mesh before road testing.

Material advantages of this shaft?

Titanium provides a favourable stiffness-to-weight ratio and superior surface corrosion resistance versus untreated steel, which can be beneficial in harsh or wet running conditions.

Is additional setup required after fitment?

After fitment, verify bearing preload and gear mesh, perform a low-speed run to check for noise or binding, and re-torque fasteners to specification to ensure reliable operation.
