HPI Savage 21 Titanium Universal Swing Shaft Wide 5mm by GPM TSAV12110  [TSAV12110]

Universal swing shaft for HPI Savage 21

This is an RC-scale replacement universal swing shaft set intended for the HPI Savage 21 platform. The parts are titanium and supplied as a 1pr set, with drive adaptor, pins, and washers included to match the wide 5mm interface noted in the product name. The component is intended for front and rear driveline use on the Savage 21 chassis and should be treated as an aftermarket hop-up for that model.

The pieces function as drop-in style swing shafts that pair with the vehicle's existing differential and hub assemblies. They provide the same mounting interfaces described in the product title, so installers can expect to reuse standard retainers and related hardware where the geometry matches the Savage 21 layout. Routine checks of pin alignment and washer placement during reassembly are recommended to ensure correct engagement.

Use this set when replacing worn swing shafts on an HPI Savage 21 or when converting to the wide 5mm adaptor arrangement, and verify fitment on your chassis before final assembly.
