EBC CSK31 Heavy Duty Clutch Spring - Kit

The EBC CSK31 Heavy Duty Clutch Spring Kit provides a performance upgrade for motorcycles experiencing clutch slippage or weakened spring tension from heat and wear. These precision-engineered springs are designed as direct OEM replacements with enhanced performance characteristics.

Key Features:

• 10% stiffer spring rate than OEM specifications for improved clutch engagement
• Prevents clutch slippage under aggressive riding conditions
• Heat-resistant construction maintains tension over extended use
• Smoother clutch engagement and faster takeoff response
• Enables quicker, more precise shifting under load
• Complete kit includes all springs needed for clutch basket

The increased spring tension delivers noticeably firmer clutch lever feel, which may require slightly more hand effort in stop-and-go traffic. However, this trade-off results in superior power transfer, reduced clutch fade during hard use, and more consistent engagement characteristics. Ideal for riders seeking OEM+ performance and reliability from their clutch system.
