Yokomo YOKB7-S5N - Shock Shaft for BD7-2014 SLF Normal Shock  [YOKB7-S5N]

BD7-2014 shock shaft for SLF

This is an RC-scale shock shaft intended for use with BD7-2014 SLF normal shocks, supplied as a direct replacement part for damper rebuilds. The part serves a single mechanical role: provide a straight, wear-resistant guide for the piston assembly inside SLF normal shocks on touring car dampers.

Installation follows standard damper service procedures: drain the shock, remove the cap and spring, extract the internal assembly, and swap the old shaft for the YOKB7-S5N. Check seal seating and retainers during reassembly to avoid leaks and maintain consistent damping performance. Do not force components; ensure smooth movement before sealing the shock.

In tuning terms the shaft affects friction, seal wear, and runout; a straight, smooth shaft helps preserve predictable damping and repeatable setup changes. Routine inspection for burrs, bends, or corrosion and replacing the shaft as part of maintenance reduces inconsistent damper behavior during track sessions.
