Yokomo YOKYS15675L Pro Shock Spring Purple Long Type 1pr  [YOKYS15675L]

Shock spring for touring cars

This Yokomo YOKYS15675L long-type shock spring is an RC-scale component made for touring car shock assemblies, offered in purple and supplied as 1pr. The supplied detail from the product name and notes specifies a 1.5mm wire diameter with a 6.75 winding count, which determines its spring behaviour compared with other springs in a tuner’s kit.

Use it as a drop-in replacement where long springs are required, or as part of a tuning progression to change suspension stiffness and response. As with any spring swap, assess ride height and spring preload after installation, and compare corner behaviour on a familiar track section to determine whether the spring achieves the desired roll and traction characteristics.

Installation notes: fit the spring concentrically on the shock shaft, seat it fully on the spring perch, and check for bind or lateral movement through the suspension travel. When testing, change only one variable at a time so you can attribute handling differences to the spring itself rather than concurrent setup changes.
