HPI Savage 21 Front and Rear Steel Wheel Shafts SSAV1139 by GPM  [SSAV1139]

Replacement front and rear wheel shafts for Savage 21

This SSAV1139 shaft set is a direct replacement part for the HPI Savage 21 chassis. The 1pr package contains front and rear wheel shafts plus the matching washers specified in the product title for a straight swap of worn or bent shafts.

Built for direct fitment, these steel shafts transfer wheel loads into the hubs while reducing play and runout. Use the original components as a reference during installation to preserve factory hub spacing and alignment.

Installation notes: inspect mating hubs and wheel hexes for wear before fitting, ensure washers sit flat against the hub faces, and tighten fasteners to the manufacturer recommended torque to avoid bearing preload or hex slippage. After initial fitting, check wheel rotation and recheck fasteners if any lateral play appears.

Setup and tuning: replacing bent or fatigued shafts restores consistent wheel geometry and helps maintain stable handling under acceleration and braking; shaft swaps are a common maintenance item after off road impacts.
