HPI Savage 21 Steel Universal Main Shaft by GPM SSAV1037L  [SSAV1037L]

Savage 21 Steel Universal Main Shaft Overview

This is an RC-scale replacement main shaft produced by GPM for the HPI Savage 21 platform, supplied as a single piece and designated for exclusive use with the SAV1014L and SAV1014vl chassis codes. The part is described as steel construction, and its role is limited to the model-scale drivetrain where it replaces a worn or damaged main shaft inside the Savage 21 transmission assembly.

Use this shaft when maintaining or repairing a Savage 21 drivetrain, or when replacing a bent or fatigued component during routine servicing. Before installation confirm the part index matches your chassis code, inspect associated bearings and retainers, and follow the vehicle manufacturer's service clearances when fitting the shaft into the gearbox and universal joint assemblies.

Installation notes: fit the shaft with the original retaining clips and check for smooth engagement with the spur and pinion interface, verify alignment in the gearbox to avoid binding, and apply a light, appropriate lubricant to mating surfaces if required by your maintenance practice. This product is intended only for RC model use on the stated Savage 21 variants.
