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

Titanium universal main shaft for HPI Savage models

This titanium universal main shaft is an RC-scale replacement part for the HPI Savage platforms listed in the product title. It acts as the central rotating shaft in the drivetrain assembly, offering a corrosion-resistant option compared with standard steel while maintaining dimensional fit for the named Savage variants.

The shaft transmits rotational load through the gearbox and differentials in typical Savage drivetrains. When replacing a bent or worn main shaft, confirm alignment and bearing seating during installation and verify correct mesh between the spur and pinion gears after reassembly. The item is supplied as a single universal shaft intended to fit the vehicle architectures named in the product title.

For tuning and workshop maintenance, use this shaft where titanium's stiffness-to-weight advantages and surface corrosion resistance are desired. Do not assume fitment beyond the listed models without checking chassis layout and part dimensions on your specific Savage variant.

Select this shaft when replacing the factory main shaft on the listed HPI Savage variants to retain drivetrain geometry while switching to a titanium component; always inspect bearings and couplings as part of the service routine.
