HPI Savage 21 Titanium Universal Front and Rear Swing Shafts TSAV12100 by GPM  [TSAV12100]

Engineered titanium universal swing shafts for Savage 21

This titanium front and rear universal swing shaft set is produced for the HPI Savage 21 chassis and carries the part reference GPM TSAV12100. The kit comprises matched shafts and installation washers, intended as a durable, lower-mass replacement for the factory steel shafts used in the Savage 21 driveline.

Functionally the shafts transfer torque from gearbox outputs to wheel hubs while permitting suspension and steering movement. Fabricated in titanium for an improved strength to mass ratio, these shafts are intended to reduce rotating mass and improve wear resistance in the transmission path. The included washers let technicians set axial clearance precisely during assembly.

Installation procedure: remove the factory swing shafts in line with Savage 21 service practice, transfer any bearings or retainer clips to the new parts if required, locate the titanium shafts into the front and rear carriers, and use the supplied washers to establish correct endplay prior to final torqueing. Verify spline engagement and manually rotate the assembly to confirm smooth operation.

Technical role: this component-level upgrade focuses on durability and reduced rotating inertia to refine drivetrain responsiveness; it is suitable for rebuilds after wear or for tuners seeking marginal improvements in drivetrain balance.

This precision GPM titanium set provides direct-fit shafts for Savage 21 users aiming to renew worn drivetrain parts or trim rotating mass; adhere to standard service checks for fitment and clearance when installing. by GPM
