A 123mm steel front and rear swing shaft intended for HPI Savage 21 applications, referenced SSAV11123. Supplied as 1 pr, the shaft replaces the original link between suspension pivots and the driveline.
Steel construction provides increased wear resistance relative to softer materials, making the shaft appropriate for scheduled maintenance or replacing worn factory components on Savage 21 models. Confirm mounting geometry and shaft length before installation.
The component operates as the pivot and load-bearing element between suspension arms and drivetrain components; its condition directly influences steering consistency and mechanical durability. Inspect pins, spacers and bearings during fitment and verify smooth articulation throughout the suspension travel.
