Kibblewhite precision valve seats are just that--precision! No matter what your powersport is--ATV/UTV, motorcycles, or PWC/snowmobile--the quality of American-crafted Kibblewhite valve seats will perform flawlessly! Their passion for cycles has created products with exceptional wear qualities, excellent thermal qualities, and resistance to micro-welding, corrosion, and burning. These valve seats are manufactured with ample material and the outer diameters are ground smooth for maximum contact and optimum heat transfer, with a generous radius on the leading edge to prevent galling. Choose either their powdered metal precision valve seats that are compatible with all types of fuel blends, or their proprietary bronze alloy seats specifically designed for use with titanium valves in high performance applications. There's only one place to go for your powersports performance valvetrain needs--Kibblewhite Precision Machining.
