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

Overview of the Big Bore Front Spring

The Yokomo YOKYSA875 Big Bore front shock spring is supplied in yellow and marked for "All Round" front suspension applications on RC scale models. It is an aftermarket spring intended for shock assemblies that accept Big Bore types.

Functionally, the spring changes spring rate and preload behaviour, altering the front suspension response. Use compatible pistons and damper oil to tune ride height and transient performance, and evaluate results on track.

To fit, remove the shock cap, replace the current spring noting orientation, set initial preload, and reassemble the shock. After fitting, check for smooth shaft movement and confirm setup with a few runs.

Advice: choose springs that match travel and tuning aims, check for wear or distortion before reuse, and keep spare springs for quick swaps. The yellow finish simplifies identification during events.
