Savage 21 Titanium Front/Rear Universal Swing Shaft Pair TSAV12100 by GPM  [TSAV12100]

Precision titanium swing shafts for Savage 21

This pair of titanium universal swing shafts is intended for the HPI Savage 21 and is listed as GPM TSAV12100. The set includes both front and rear shafts plus washers, allowing replacement of standard steel shafts where lower rotating mass and improved wear characteristics are desired.

The shafts carry torque from the gearbox output to each hub while still permitting suspension travel and steering articulation. Titanium provides a useful strength-to-weight balance versus steel, and the supplied washers help establish correct axial clearance during fitment.

Fitting notes: remove the original swing shafts per Savage 21 service practice, move over any bearings or clips required, fit the new shafts into the front and rear carriers, and use the washers to dial in endplay before final tightening. Manually cycle the drivetrain to ensure smooth engagement and alignment.

Application: this is a component-level upgrade for owners replacing worn drivetrain parts or seeking a small reduction in rotating mass to refine drivetrain feel for off-road duties.

This GPM titanium kit provides a direct-fit option for Savage 21 drivers wanting refreshed shafts or a modest reduction in rotating mass; always verify spline engagement and clearance after installation.
