GPM SAV13170/SH HPI Savage 21 Steel Damper Shaft  [SAV13170/SH]

Replacement steel shaft for Savage 21 shocks

A direct replacement shaft for Sav13170 dampers used on HPI Savage 21 models. Supplied as 1 pr, the part is made from hardened steel to serve as the internal rod within the damper assembly and is intended for routine shock maintenance, rebuilds, and part swaps.

Fitting requires standard disassembly of the Sav13170 damper, removal of the old shaft, and careful reassembly. Inspect seals, bushings and piston condition during the rebuild, and verify the new shaft runs straight and smooth to avoid binding or inconsistent damping.

For suspension tuning and repairs the shaft restores correct damper geometry and travel when worn internals are replaced. Use this component when you need a straight, undamaged damper rod to keep the Savage 21 running with predictable suspension feel.
