EBC CSK33 Heavy Duty Clutch Spring - Kit for Motorcycles

The EBC CSK33 Heavy Duty Clutch Spring Kit is designed to replace worn or heat-damaged OEM clutch springs with upgraded components that deliver improved performance and durability. These precision-engineered springs are approximately 10 percent stiffer than stock specifications, providing enhanced clutch engagement and better power transfer.

Key Features:

• 10% stiffer than OEM springs for improved clutch performance
• Prevents clutch slippage caused by heat and wear over time
• Smoother, faster clutch engagement for improved takeoff
• Enables quicker, more precise gear shifting
• Direct OEM replacement upgrade—sold as complete kit
• High-quality steel construction for long service life

The increased spring tension results in a slightly firmer clutch lever feel, which may be more noticeable during stop-and-go riding or heavy traffic conditions. However, this trade-off delivers significant benefits including reduced clutch slip, more consistent engagement, and faster shift response—making the CSK33 kit ideal for performance-oriented riders and those who demand reliable clutch operation under demanding conditions.
