Wiseco CSK027 Clutch Spring Kit for Suzuki RM-Z450

The Wiseco CSK027 Clutch Spring Kit is a direct-replacement spring set engineered to restore and improve clutch performance. Manufactured from premium-grade steel, each spring undergoes a rigorous shot-peening and heat-treating process that enhances fatigue resistance and extends service life under demanding riding conditions.

Key Features:

• Premium steel construction for durability and consistent spring rate
• Shot-peened finish increases surface strength and resistance to stress fractures
• Heat-treated for lasting performance and resistance to spring fade
• Stiffer-than-stock spring rate ensures positive clutch lockup and eliminates clutch slip
• Sold as a complete spring kit — everything needed for a full clutch spring replacement

Wiseco clutch components are trusted by riders at every level of dirt bike competition. The CSK027 is a straightforward upgrade over worn OEM springs, delivering firmer, more predictable clutch engagement whether you're on the track or trail.
