HPI Savage 21 Titanium Front and Rear Shafts TSAV1139 by GPM  [TSAV1139]

Savage 21 wheel shaft upgrade

This titanium front and rear wheel shaft set is produced for the HPI Savage 21 chassis and is supplied under model TSAV1139 by GPM. The kit arrives as a matched 1pr with washers included to replace or upgrade the OEM wheel mounting components.

Engineered for direct installation, the shafts secure wheels on the hub carrier and help keep wheel alignment consistent under load. Fitment requires standard wheel and hub disassembly, inspection of bearing and suspension clearances, and reassembly using factory torque settings unless otherwise required.

Its straightforward service design suits routine upkeep, corrosion-resistant durability upgrades, and subtle wheel-position tuning while preserving main suspension geometry.

For hobby mechanics and tuners, these titanium shafts give a corrosion-resistant, fitting-compatible choice that keeps wheel mounting function aligned with the original system.
