HPI Savage 21 Front/Rear Steel Wheel Shafts SSAV1139 technical fitment by GPM  [SSAV1139]

Front and rear wheel shaft replacement for Savage 21 chassis

This SSAV1139 shaft set is provided as a direct replacement for the HPI Savage 21. The 1pr set contains both front and rear wheel shafts plus the matching washers referenced in the product title for direct swap of worn or bent components.

Designed for accurate seating and load transfer, these steel shafts aim to keep wheel runout and lateral play to a minimum when fitted to hubs that match the original geometry. During installation, reference original parts to preserve hub spacing and alignment tolerances.

Fitment guidance: inspect hub bores, wheel hexes and bearing condition before assembly, ensure washers sit flush to hub faces, and apply recommended fastener torque to avoid bearing preload or hex movement. After fitting, perform a wheel spin check and confirm there is no side play.

Maintenance and handling: replacing damaged or fatigued shafts restores correct wheel geometry and supports predictable vehicle response under acceleration and braking loads; shaft replacement is a standard service procedure after impact events.
