EBC CSK918 Heavy Duty Clutch Spring - Kit Diaphragm Type

The EBC CSK918 Heavy Duty Clutch Spring Kit is designed to replace worn or heat-damaged OEM clutch springs with upgraded, performance-oriented components. These springs are engineered to be approximately 10 percent stiffer than stock springs, providing improved clutch engagement and enhanced durability under demanding riding conditions.

Key Features:

• 10% stiffer than stock springs for improved clutch performance
• Diaphragm-type clutch spring design
• Prevents clutch slippage from heat exposure and wear
• Provides smoother, more positive clutch engagement
• Enables faster, more precise shifting under acceleration
• Direct OEM replacement with performance upgrade
• Sold as complete kit with all necessary springs

The increased spring tension results in slightly firmer clutch lever feel, which may be noticeable during stop-and-go traffic riding. However, this trade-off delivers significant benefits including reduced clutch slip, more consistent engagement point, and improved power transfer during aggressive acceleration and speed shifting. Ideal for riders seeking enhanced clutch performance and longevity.
