Yokomo YOKB7-S3S spring cup for SLF short shock (BD7-2014) - spring seat for SLF short shocks  [YOKB7-S3S]

SLF short shock spring cup (BD7-2014)

This RC-scale accessory is a replacement spring cup specifically formed for SLF short shock assemblies and named in the product as a match for BD7-2014 dampers. Its role is to provide a stable seating surface for the spring inside short-stroke shock bodies and to allow precise adjustment of spring preload and spring seating height without modifying the shock shaft or spring retainer.

Installation is straightforward for anyone familiar with basic shock servicing: disassemble the shock body, remove the existing spring cup and spring, position the new spring cup on the shock shaft or lower assembly as required by your SLF short-shock layout, then reassemble and check free movement. Use the same seals and spacers from the original assembly to maintain damper oil containment and stroke characteristics.

In tuning terms, swapping the spring cup affects spring seat position and preload range more than oil damping. Small changes to the cup height can alter ride height and initial spring engagement, which in turn impacts chassis balance and transient response. Inspect for lateral play after fitting and recheck preload and endstops during the first test runs.
