EBC CSK908 Heavy Duty Clutch Spring - Kit Diaphragm Type

The EBC CSK908 Heavy Duty Clutch Spring Kit provides an OEM upgrade solution for motorcycles with diaphragm-type clutches. These precision-engineered clutch springs are designed to replace worn or heat-damaged stock springs, restoring optimal clutch performance and extending clutch life.

Key Features:

• 10% stiffer spring rate than OEM for improved clutch engagement
• Prevents clutch slippage from prolonged heat exposure and wear
• Smoother, faster clutch engagement for improved takeoff performance
• Enables quicker, more precise shifting under aggressive riding conditions
• Complete kit with all springs needed for installation
• Direct OEM replacement fitment

The increased spring tension provides firmer clutch lever feel, which may require slightly more effort during stop-and-go traffic riding. However, this trade-off delivers noticeably improved clutch response, reduced slippage, and enhanced power transfer—particularly beneficial for spirited riding and performance applications.
