This is an RC-scale shock cylinder designed by Yokomo under model YOKB7-S4S, intended for use with SLF short shock assemblies referenced alongside BD7-2014 in the product name. The component serves as the internal body that guides piston travel in short-travel dampers and is intended for hobbyist replacement or maintenance work on compatible short-shock setups.
Installation is straightforward for those familiar with oil shock maintenance, the cylinder is fitted into the shock housing and works with existing pistons, seals, and shafts of the SLF short shock layout, inspect O-rings and bushings during service and ensure proper oil fill and bleed for consistent damping.
In tuning terms the cylinder forms part of the damper assembly that affects flow characteristics and stroke behaviour in short-travel suspensions, it should be evaluated together with pistons, oil weight, and spring rate to achieve the desired handling balance on 1/10 on-road setups.
