AV&V™ Extreme Duty Valve Spring Kits for Kawasaki
Manufactured from ultra clean high silicon Kobe alloy wire then micro shot peened and nitrided, these springs have been designed to be used with high performance cams and/or Steel conversion valves that replace Titanium valves.
When changing OEM titanium valves for AV&Vs Extreme Duty Stainless Steel Valves, you must also upgrade your springs for AV&Vs Extreme Duty Springs due to the need for higher pressure and toughness. To order Intake Springs only, choose kits VSKXXXX-i.
