HPI Savage 21 Front/Rear Universal Swing Shaft (CVD Design) by GPM SSAV12100C  [SSAV12100C]

Universal swing shaft for Savage 21

This is a steel front and rear universal swing shaft designed for HPI Savage 21 platforms, supplied as a 1pr set with washers. The component follows a CVD-style configuration intended for RC-scale drivetrain use and is offered as an aftermarket replacement part by GPM.

In practical terms the shaft replaces the stock swing shaft on Savage 21 units where the same mounting and coupling geometry is used. The included washers help with basic spacing and securement; check existing hub and carrier interfaces for fit before final assembly.

For installation, use the original mounting points and standard RC hand tools such as hex drivers. Inspect mating pins, hexes and nearby 走珠軸承 for wear when replacing shafts, and verify driveline alignment at full suspension travel to avoid binding.

Use this set when replacing worn swing shafts or when a steel CVD-style shaft is preferred for Savage 21 drivetrain maintenance and tuning; confirm fit before final installation.
