Engineering overview

The SSAV12110 swing shaft is supplied as a matched front and rear pair for the HPI Savage 21 driveline where the wide 5mm profile is required. The component is steel and configured to accept the supplied adaptor, retaining pins and washers for direct fitment to the stock hub geometry.

Designed as a service replacement, this shaft reinstates proper coupling and alignment in drivetrains specifying a 5mm wide shaft. The component supports routine maintenance and light setup changes without implying performance upgrades beyond dimensional compatibility.

Installation procedure: insert the shaft into the hub and suspension assemblies, fit the adaptor, and secure with the provided pins and washers. Confirm axial alignment and correct seating of pins during assembly, and reverify engagement after an initial test run, especially when used with nonstandard hub or hex dimensions.

Use the SSAV12110 pair to restore correct driveline geometry on Savage 21 models specifying 5mm wide shafts; verify seating and alignment during installation and after a controlled break-in run.

What tolerance checks are recommended on fitment?

Verify lateral runout at the hub, axial clearance through the adaptor, and that pin holes align cleanly; minimal play ensures reliable driveline engagement.

Are the supplied pins the correct material?

Pins and washers are matched to the shaft for standard assembly; inspect for proper fit and replace if any deformation is observed during service.

Should I modify setup when using aftermarket hubs?

When using aftermarket hubs, confirm hex width and hub bore compatibility with the 5mm shaft profile and adaptors; modify spacer or adaptor selection as required.

Recommended post-fit checks?

After installation, run the model under light load to confirm smooth engagement, then re-torque fasteners and recheck pin seating and alignment.
