Yokomo YOKYS1280 - HSS Long Shock Spring (Pink)  [YOKYS1280]

Long shock spring for RC suspension

This is a Yokomo YOKYS1280 HSS long shock spring supplied in pink, intended as an RC-scale accessory for shock absorber assemblies. It is presented as a direct-purpose spring to replace or vary the feel of long-travel shock units found on many scale models, and its HSS designation is used here as the product identifier.

Installation follows standard RC shock spring procedures: remove the shock from the model, disassemble the shock cap if required, slide the spring onto the shock shaft over the damper body and retainer, then reassemble and check for correct travel and end clearance. The part is intended for model use only and should be matched to the shock's available travel to avoid binding.

In tuning, a long shock spring like this is used to adjust ride height, initial response and mid-stroke support. Use it to compare behaviour against your current springs during setup changes, and pair it with appropriate spacers or end preload adjustments to reach the desired suspension balance for your scale RC application.
