Yamaha FZR/FZS/GP/FX Bronze Valve Guides Set of (16)

The valve guide supports the intake/exhaust valve stem, stabilizes the valve attitude and allows heat transfer from the valve to the cylinder head for more efficient cooling hence, it needs to be precision machined for exact valve concentricity, durability and made using specific materials. 

Our Pro Valve Racing Bronze Valve Guides are made using our proprietary bronze alloys and have superior friction resistance and mechanical properties. Using our alloys lends itself to a more predictable expansion rate which allows you to run a much tighter valve to guide clearance "As tight as .0008" for improved lateral valve stability and reduced valvetrain wear.
