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

Yokomo Big Bore Front Spring for Everyday RC Use

This Yokomo YOKYSA875 front shock spring is an RC-scale Big Bore option in yellow, marked for "All Round" applications. It is intended as a straightforward spring upgrade for shock assemblies that accept Big Bore springs, helping tune front suspension response on scale models.

In practice, the spring alters front spring rate and preload behavior, which changes how the suspension reacts to inputs. Pair it with compatible shock pistons and appropriate damper oil to achieve the ride height and transient response you want, and evaluate changes on track rather than relying on fixed performance numbers.

Installation follows standard front shock spring procedures: remove the shock cap, swap the spring while noting orientation, set an initial preload, and reassemble. After reassembly, check for smooth shaft travel and absence of binding, and verify setup after a few runs.

Tips: choose springs that match travel and chassis tuning goals, inspect springs for wear or bends before reuse, and keep spares for quick changes. The yellow finish makes it easy to identify springs during a race day.
