EBC CSK3 Heavy Duty Clutch Spring - Kit

The EBC CSK3 Heavy Duty Clutch Spring Kit provides a performance upgrade for motorcycles experiencing clutch fade or slippage from worn or heat-damaged springs. These precision-manufactured springs are engineered to be approximately 10% stiffer than OEM specifications, delivering improved clutch engagement and extended service life.

Key Features:

• 10% stiffer spring rate than stock for firmer clutch engagement
• Prevents clutch slippage caused by heat exposure and wear
• Enables smoother takeoff and faster gear shifts
• Sold as a complete kit with all springs needed for installation
• Direct OEM replacement upgrade

The increased spring tension results in a slightly firmer clutch lever feel, which may cause hand fatigue during extended stop-and-go riding. However, this trade-off delivers noticeably crisper clutch engagement, reduced slippage under hard acceleration, and improved shifting performance—particularly beneficial for aggressive riding and performance applications.
