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

Savage 21 Universal Main Shaft Description

This steel universal main shaft is a direct replacement option for the HPI Savage 21 and is intended exclusively for the SAV1014L and SAV1014vl chassis codes. It replaces a worn or bent main shaft inside the model-scale transmission assembly.

Use this shaft when performing gearbox repairs or standard maintenance on the Savage 21 drivetrain. Confirm chassis compatibility before purchase, inspect bearings and retaining clips, and follow the vehicle service clearances when seating the shaft into the gearbox and universal joints.

Fitting advice: secure the shaft with the original retaining clips where possible, ensure smooth engagement with spur and pinion gears, check for correct gearbox alignment to avoid binding, and apply a light lubricant to mating surfaces if required by your servicing method. This part is intended solely for the listed Savage 21 variants.
