Yokomo YOKYSA775 Big Bore Front Shock Spring (Green) for All-Round Setups  [YOKYSA775]

Large-diameter front spring for setup tuning

This Yokomo YOKYSA775 front shock spring is an RC-scale replacement spring intended for general all-round setups. The big bore designation indicates a spring designed to work with larger-diameter shock bodies and to alter suspension response without requiring other component changes.

Installation is straightforward: remove the shock cap and spring retainer, swap the spring onto the shock shaft and reassemble. No special tools are required beyond the standard hobby hex driver and basic shock disassembly tools, and the part is intended only for model cars and model suspension assemblies.

In tuning terms this spring changes front-end compliance and compression feel; it is useful when you want a firmer initial compression or a different linearity from the stock spring. Expect to pair spring choice with shock oil and spring perch settings when refining handling, keeping adjustments incremental and testing on the same course conditions.
