Yokomo YOKB7-S3N Spring Cup for SLF Normal Shock (Black)  [YOKB7-S3N]

Spring cup for SLF normal shock

This is an RC-scale spring cup designed for SLF Normal Shock applications, supplied under the Yokomo YOKB7-S3N designation. The part functions as the spring seat between the coil spring and the shock body on dampers that follow the SLF Normal Shock layout, and it is finished in black to match common team setups.

Compatibility in the product title identifies BD7-2014 as the referenced chassis/shock family; do not assume fitment beyond the stated BD7-2014 and SLF Normal Shock context without verifying against your shock shaft and spring inner diameter. This component is intended to locate the spring axially and provide a stable contact surface to preserve consistent preload and alignment during track running.

Installation is straightforward for experienced model technicians: the cup fits over the shock shaft and sits between the spring and shock body or retainer as required by your shock assembly. Check orientation and seating before final assembly and confirm free movement of the shaft through its travel after the spring is installed. This part is described as a replacement or maintenance item for hobby-grade touring car suspension assemblies and is not for full-size vehicle use.
