Savage 21 Front/Rear Wheel Shaft Pair SSAV1139 Upgrade by GPM  [SSAV1139]

Front and rear wheel shaft replacement for Savage 21

This SSAV1139 shaft set is offered as an aftermarket replacement compatible with the HPI Savage 21 chassis. Supplied as a 1pr set, it includes both front and rear shafts together with the corresponding washers listed in the product title.

These steel shafts are intended for direct swap with the original parts to restore correct wheel support and reduce side play and runout. Refer to the existing hardware when fitting to keep hub spacing and alignment consistent with factory settings.

Fitting advice: examine the mating hubs and wheel hexes for wear prior to installation, confirm washers are flush to hub faces, and secure fasteners to recommended tightness to prevent bearing preload or hex slippage. Run the model and recheck torque after a short test run.

Service note: swapping out bent or worn shafts is a typical maintenance task that returns predictable wheel geometry and improves vehicle control during hard acceleration and braking.
