Yokomo YOKB7-S3S SLF short-shock spring seat compatible with BD7-2014  [YOKB7-S3S]

Short SLF shock spring seat tailored to BD7-2014 dampers

This replacement spring cup is formed for SLF short-shock assemblies and called out for BD7-2014 dampers. It creates a stable seating surface for the coil and lets you micro-adjust spring position and preload without modifying the shock shaft or the factory spring retainer.

To install, open the damper, remove the spring and old cup, slide the new cup into the required position on the shaft or lower housing per your SLF short-shock layout, then reassemble and verify free movement. Use the existing seals and spacers to maintain oil retention and stroke geometry.

On-track, the cup alters where the spring takes load and the available preload window rather than altering internal damping. Minor cup height changes can influence initial response, roll balance and ride height. After fitting inspect for lateral movement and verify preload and travel limits before full-speed runs.
