This shock shaft is supplied for use with BD7-2014 SLF normal shocks and serves as a direct replacement when rebuilding dampers. The shaft's basic mechanical function is to provide a straight, wear-resistant guide for the piston assembly inside SLF normal shocks on touring cars.
Installation uses standard damper service steps: remove oil, take off the cap and spring, extract the internal assembly, and replace the degraded shaft with the YOKB7-S5N. Check seals and retainers carefully during reassembly to prevent leaks and preserve consistent damping. Ensure parts slide freely and do not force components before sealing.
Regarding fit and compatibility, this shaft influences friction and runout; keeping it true and smooth supports predictable damping and repeatable setup changes. Inspect for burrs, bends, or corrosion during service and replace when these faults appear to avoid erratic damper performance.
