The EBC Powersports CSK90 Heavy-Duty Clutch Spring Kit is designed to help restore clutch performance and reduce the risk of premature or rapid clutch wear. Tired clutch springs can contribute to clutch slip, especially under increased engine load. Replacing the springs during a clutch rebuild provides a practical upgrade for riders seeking more consistent clutch engagement and improved power transfer.

Each CSK90 kit uses premium spiral-wound clutch springs manufactured from heat-treated steel for extended service life. The spring gauge tension is measured to support consistent performance across the set, while the increased spring pressure helps upgrade clutch holding power. Although lever pressure is increased, the change is designed to be minimally noticeable during normal riding. EBC manufactures these clutch springs in the United Kingdom to exacting quality standards.

Fitment: Designed to fit select 2002–2004 Honda VTX1800 models, including the VTX1800C, VTX1800R, VTX1800S, and VTX1800N where applicable.
