KIBBLEWHITE Valve Seat 10-HC542

High-performance titanium valves demand a seat material engineered to match their demands—standard iron seats simply can't handle the thermal stress and wear cycles. The KIBBLEWHITE 10-HC542 copper-based seat delivers the thermal conductivity and durability required for sustained racing applications, whether you're building a street bike or a full-competition engine. Backed by two years of KPMI R&D testing across 4-valve and 5-valve configurations, this seat has proven itself in the hands of championship-winning builders worldwide.
