LOSI PROMOTO-MX 4x65mm Shock Shaft LOS263010 by GPM  [MXDP/PIN]

PROMOTO-MX shock shaft details

This 4x65mm shock shaft is made for the listed LOSI PROMOTO-MX motorcycle RTR models and fits shock assemblies that accept a 4mm diameter, 65mm length shaft. It is constructed from 4140 medium carbon steel and receives a zinc-plated surface hardening treatment to improve wear resistance and maintain dimensional stability during service. The item is supplied as a single pcs unit and is intended as a replacement or service spare for routine suspension maintenance and tuning.

Functioning as the key structural rod inside the damper, a straight, correctly sized shaft restores alignment and reduces unwanted flex that alters damping feel. Before fitting, confirm internal shock bore, eyelet clearances and travel to ensure proper fitment and avoid binding.
