Intake Valve, standard size, sold individually. Replacement for OEM # 70-4603

Kibblewhite produces world-class components here in the USA which are found on everything from vintage street bikes to Larry 'Spiderman' McBride's Top Fuel World Champion drag bike and Alp Sungurtekin's world-recording holding 175mph 650cc Triumph land speed racer. In Kibblewhite's own words:

These OEM style replacement valves exceed the material and tolerance specs of the original factory pieces. The valves are one piece stainless steel forgings. They are fully CNC machined with swirl polished tulip profiles. Stellite has been welded on to the tips to resist the deformation that can be caused by the impact of the rocker arm.

Head Diameter: 40.64mm / 1.600"
Stem Diameter: 7.9mm / 0.3105"
Tulip: R 1.500"
Overall Length: 3.850"

USA Manufacturing

Here at Lowbrow Customs we believe strongly in supporting US manufacturing. We have created multiple annual scholarships, one with the Lincoln Electric Welding School and another with Tri-C (Cuyahoga Community College) for students in financial need who are pursuing workforce training. From TIG welding to machining, this is the backbone of manufacturing in the United States. Want to learn more? Click here.
