HPI Savage/Savage X/Savage Fluorescent Titanium Universal Main Shaft by GPM TSAV1037  [TSAV1037]

Titanium universal main shaft for Savage

This titanium universal main shaft is an RC-scale replacement part intended for HPI Savage platforms listed in the model name. It serves as the central rotating shaft in the drivetrain assembly, providing a corrosion-resistant alternative to standard steel shafts while maintaining dimensional fit for the specified Savage models.

The shaft's role in a Savage drivetrain is straightforward: it transfers rotational load through the gearbox and differentials. When replacing a worn or bent main shaft, confirm alignment and bearing seating during installation, and check for correct mesh with spur and pinion gears after reassembly. This component is supplied as a single universal shaft intended to fit the vehicle architectures named in the product title.

For tuning and maintenance, use this shaft where a titanium material characteristic is preferred for its stiffness-to-weight ratio and surface corrosion resistance. Do not assume fitment beyond the listed models without verifying chassis layout and part dimensions on your specific Savage variant.

Choose this shaft when replacing the original main shaft on the listed HPI Savage variants to retain drivetrain geometry while switching to a titanium component; always inspect related bearings and couplings during service.
