Kibblewhite Shim in Tappet Valve Spring Kit

Fit: 05-08 Suzuki GSXR1000

These valve springs are highly recommended for most applications.

Kit includes:
-Dual Chrome Silicone Valve Springs
-Lightweight Titanium Retainers
-H.T. Steel Base Washers
-Valve Spring Shims (for use with Stainless Steel Valves)
-Shim in Tappet Buckets

These valve springs are good to .445" of valve lift on the intake and exhaust with Titanium Valve setup. This kit requires tightened installed height to provide enough spring pressure for Stainless Valves. This uses the included Valve Spring Shims to tighten installed height, but lessens max lift, if setup for stainless valves, only allows for .370" of valve lift, intake and exhaust. These springs also include titanium retainers for the lightest retainer possible, allowing for increase RPM and lighter spring forces. Sunk guides are required with higher lift camshafts.

The Shim In Tappet Setup improves reliability and issues with retainer wear and shim dislodging from a worn retainer. This setup moves the valve shim from being retained but the valve retainer to the valve teppet. The benefit of this setup is it reduces retainer wear and ovaling (resulting from the valve shim being hardened steel and the retainer is titanium, the shim is harder than the retainer) into the Hardened Steel Valve Tappet. When you have excessive retainer wear from the valve shim, it can no longer properly retain the valve shim and may kick out the shim while the engine is operating, and can cause other damage as a result.
