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

PROMOTO-MX shaft description

This 4x65mm shock shaft is intended for the listed LOSI PROMOTO-MX motorcycle RTRs and is suitable for shock bodies that accept a 4mm diameter, 65mm length rod. Manufactured from 4140 medium carbon steel with a zinc-plated surface hardening process, the shaft improves resistance to wear and helps retain dimensional accuracy during use. Supplied as a single pcs replacement part for suspension servicing and tuning.

The shaft serves as the structural guide within the damper; replacing a bent or fatigued shaft restores alignment and reduces unwanted flex that can upset damping behaviour. Always verify internal shock dimensions, spacer arrangement and end fitting clearances prior to installation to ensure correct fitment.
