Product Details

The EBC CSK158 Heavy Duty Clutch Spring Kit delivers enhanced clutch performance for motorcycles through precisely engineered spring technology. These premium replacement springs are designed to minimize clutch slippage and extend component life in demanding riding conditions.

Key Features:

  • 10% stiffer spring rate compared to OEM specifications for improved clutch engagement
  • Minimizes clutch slip under acceleration and high-load conditions
  • Reduces clutch plate wear for extended service life
  • Complete spring set included for full clutch basket replacement
  • Precision-manufactured to exacting tolerances for consistent performance

EBC CSK Series springs are engineered for riders who demand reliable clutch performance whether on the street or track. The increased spring pressure ensures positive engagement while maintaining smooth clutch feel. These springs work with OEM friction and steel plates, or can be combined with EBC friction plate kits for a complete clutch system upgrade. Professional installation recommended to ensure proper clutch basket assembly and adjustment.

Note: EBC clutch components are not recommended for use with fully synthetic motor oils.

Very pleasant, easy process. Hopefully part ships quickly as my car is out of service until the part arrives.

Great Prices, would like to see better descriptions.

Great price and easy to shop.

Great company to deal with. I placed an order with them (albeit an incorrect shipping address) and before you know it I'm expecting delivery in a very short amount of time. I also did have to call and attempt to correct my address error when the customer service rep let me know that all is well and set to be delivered to the correct address. I appreciate the fact that the gentleman on the other end of the phone was reassuring, courteous, and professional. I'd certainly do business with them again as the prices and customer service can't be beat!

Had everything I needed and had the best price
