HPI Savage 21 Titanium Front/Rear Wheel Shaft by GPM TSAV1139  [TSAV1139]

Wheel shaft for HPI Savage 21

This titanium front and rear wheel shaft set is made for use with the HPI Savage 21 chassis, supplied by GPM under model TSAV1139. The package includes the shafts and matching washers as a 1pr set for direct replacement or upgrade of worn wheel mounting hardware.

Designed as a drop-in replacement, the shafts serve to secure wheels to the hub carrier and to maintain consistent wheel alignment under load. Use basic disassembly of the hub and wheel assembly to fit the shafts, verify clearance around the wheel bearings and suspension components, and retain factory torque settings where applicable.

The neutral, service-focused design makes these shafts suitable for hobby maintenance, durability upgrades, and finer wheel-position tuning without altering primary suspension geometry.

For builders and tuners working on HPI Savage 21 rigs, these titanium shafts offer a corrosion-resistant alternative to stock parts while keeping fitment and function consistent with the original wheel mounting system.
