HPI Savage Drivetrain Titanium Main Shaft TSAV1037 by GPM  [TSAV1037]

Replacement titanium main shaft for Savage

This titanium universal main shaft is an RC-scale replacement intended for the HPI Savage platforms noted in the product title. It serves as the central rotating shaft within the drivetrain assembly and provides a corrosion-resistant alternative to standard steel while maintaining dimensional compatibility with the listed Savage variants.

Within a Savage drivetrain the shaft transmits rotational load through gearbox and differentials. When swapping a worn or bent main shaft, ensure correct bearing seating and alignment during fitting and verify spur and pinion mesh after reassembly. The component is supplied as a single universal shaft designed to suit the vehicle architectures named in the product title.

For tuning and routine service select this shaft where titanium's stiffness-to-weight ratio and surface corrosion resistance are desired. Do not assume fitment beyond the listed models without confirming chassis layout and part dimensions for your specific Savage variant.

Use this shaft to replace the original main shaft on the listed HPI Savage variants to preserve drivetrain geometry while upgrading to titanium; always inspect bearings and couplings during any service intervention.
