HPI Savage 21 Drivetrain Main Shaft SSAV1037L by GPM  [SSAV1037L]

Steel Main Shaft for Savage 21 - Product Summary

A single-piece steel main shaft made for use with the HPI Savage 21, this replacement is intended exclusively for SAV1014L and SAV1014vl chassis codes. It serves as a drop-in option to replace a compromised main shaft inside the Savage 21 transmission assembly.

The shaft suits routine servicing and repair work where the existing component is bent or shows fatigue. Confirm the chassis index before ordering, examine bearings and retaining parts, and follow recommended clearances while inserting the shaft into the gearbox and universal joint areas.

Quick fit guidance: fit using original retaining clips where practical, ensure the shaft engages the spur and pinion without binding, check gearbox alignment after assembly, and use light lubrication on contact surfaces if that matches your maintenance practice. This product is only for the specified Savage 21 models.
