EBC CSK909 Heavy Duty Clutch Spring - Kit

The EBC CSK909 Heavy Duty Clutch Spring Kit is designed to replace worn or heat-damaged OEM clutch springs with a performance upgrade that improves clutch engagement and shifting response. These springs are engineered to be approximately 10 percent stiffer than stock springs, delivering more positive clutch engagement and preventing slippage under demanding riding conditions.

Key Features:

• 10% stiffer than OEM springs for improved clutch performance
• Prevents clutch slippage caused by heat exposure and wear
• Smoother, more positive clutch engagement
• Faster, more precise shifting with reduced effort during speed shifts
• Complete kit with all necessary springs for installation
• Direct OEM replacement with performance enhancement

The increased spring tension provides firmer clutch feel and more consistent engagement, particularly beneficial for spirited riding and performance applications. Note that the slightly increased lever effort may be noticeable in stop-and-go traffic conditions, but the trade-off is improved clutch longevity and sharper power delivery.
