Yokomo YOKYSA875 - Big Bore Front Shock Spring (Yellow) for All Round  [YOKYSA875]

Big Bore front shock spring for general RC use

This is an RC-scale front shock spring offered as a Big Bore option, supplied in yellow and labeled for "All Round" use. It is intended as a direct spring upgrade within shock assemblies that accept Big Bore springs, serving a straightforward role in front suspension setup for RC models.

Functionally, the spring changes how the front suspension responds to inputs by altering spring force and preload behaviour. Use it as part of a balanced setup together with appropriate shock pistons and damper oil for the desired ride height and transient response. Avoid assuming concrete performance figures, instead assess changes on-track and adjust preload or shock oil accordingly.

Installation is standard for front shock springs: remove the shock cap, replace the existing spring while observing spring orientation, set initial preload, and reassemble the shock. Check for binding and smooth shaft travel after reassembly. Routine checks after a few runs help confirm whether further tuning is needed.

Practical tips: match the spring choice to suspension travel and chassis tuning goals, inspect for wear or bending before reuse, and keep spare springs in the pit box for quick changes between runs. The yellow colour makes visual identification simple when swapping springs during a meet.
