HPI Savage 21 123mm Steel Front/Rear Swing Shaft by GPM SSAV11123  [SSAV11123]

Front/Rear swing shaft for Savage 21

This swing shaft is a steel front and rear linkage designed for the HPI Savage 21 chassis, listed as SSAV11123 by GPM. At 123mm length and supplied as 1 pr, the part replaces the stock front/rear swing shafts used where the suspension and drivetrain meet the chassis.

As an RC-scale replacement component, the steel construction provides higher wear resistance compared with softer materials, making it suitable for routine maintenance or replacing worn shafts on Savage 21 models. Fitment is limited to the Savage 21 platform stated in the product name; confirm match with your vehicle's existing mounting points before installation.

The part's role in tuning and setup is straightforward: it serves as the pivot and load-bearing link between the suspension arms and the drivetrain, so shaft condition affects steering response and durability rather than electronic or motor performance. Inspect mating pins and bearings when you fit the shaft and verify smooth articulation through the suspension travel.

• Material: steel, length: 123mm as specified in the product name.
• Supplied quantity: 1 pr as indicated in the title.
• Purpose: replacement for front and rear swing shaft assemblies on HPI Savage 21 models.
