Technical overview for PROMOTO-MX shaft

Engineered as a direct replacement shaft for the specified LOSI PROMOTO-MX motorcycle RTRs, this 4x65mm rod is produced from 4140 medium carbon steel with a zinc-plated surface hardening treatment to increase fatigue life and wear resistance. The component is supplied as a single pcs unit and is intended for suspension rebuilds, maintenance and precise tuning operations.

In damper assemblies the shaft is a primary structural member that controls alignment and reduces unwanted flex which can alter damping characteristics. Confirm the shock inner bore, spacer stack and eyelet clearances prior to installation to ensure correct alignment and prevent premature wear.

What tolerances should I expect on shaft diameter?

The shaft is manufactured to RC service tolerances suitable for 4mm internal bushings; verify your shock bush ID and replace worn bushes to maintain proper clearance and motion.

Is the surface hardening appropriate for high-cycle use?

The zinc-plated surface hardening treatment improves surface wear resistance for typical hobby use; for extreme duty consider additional protective measures or alternative coatings.

Any fitment checks recommended before assembly?

Measure shaft length against shock travel, confirm end fitting alignment and verify that all retaining pins and bushes match the new shaft to avoid preload or binding issues.
