High-spec wheel shafts for Savage 21

These CNC-grade titanium front and rear wheel shafts are manufactured for the HPI Savage 21 chassis and carry the model designation TSAV1139. The set is delivered as a matched 1pr with washers, intended for technicians seeking a corrosion-resistant, long-wearing alternative to standard wheel mounting hardware.

Designed for drop-in installation, the shafts locate the wheel on the hub carrier and preserve designed wheel alignment under dynamic load. Installation requires routine hub and wheel disassembly, verification of bearing and suspension clearances, and reassembly to specified torque values to ensure correct preload and retention.

The component geometry is neutral to suspension kinematics, allowing tuners to improve service life and corrosion resistance without altering primary suspension dimensions or track geometry.

Specifications

  • Item Front/Rear Wheel Shaft with Washers
  • Material Titanium
  • Model Number TSAV1139
  • Compatibility HPI Savage 21
  • Quantity 1pr set

For precision-focused builders and workshop tuners, these titanium shafts offer a durable, dimensionally consistent replacement that maintains original wheel mounting function while improving corrosion resistance.

What tolerances should I check during installation?

Verify axial clearance at the bearing face and radial running clearance across the hub; ensure washers seat flat and that retaining fasteners apply consistent preload without binding the bearing.

Are there any heat treatment or coating considerations?

These shafts are supplied as finished titanium parts; no additional heat treatment or coatings are required, though routine inspection for fretting and wear is recommended in high-mileage applications.

What installation torque is recommended for retaining hardware?

Follow factory or hub manufacturer torque specifications for retaining bolts and nuts to achieve correct clamping without overloading shafts or bearings; if unsure, consult HPI setup data for Savage 21 wheel retention values.
