Yokomo YOKYS15675L Touring Car Long Shock Spring Purple 1pr  [YOKYS15675L]

Extended shock spring for suspension tuning

The Yokomo YOKYS15675L long-type shock spring comes in purple and is supplied as one pair for touring car shock assemblies. Its 1.5mm wire diameter and 6.75 windings create a defined spring characteristic that affects both initial stiffness and mid-travel behaviour compared with other options in a setup box.

Install it when you need more travel or a different roll balance; it works well as a drop-in or as part of staged spring changes to refine handling. After fitting, verify ride height, preload, and test on a repeatable section of track to gauge changes to traction and roll stability.

Installation tip: ensure the spring is seated concentrically on the shaft and clear of any lateral contact throughout suspension travel. Limit variables during testing so changes are attributable to the spring itself.
