GM 6.6L Duramax Black Lightning Diesel Performance Valves | Set of 8

QualCast

Black Lightning Diesel Performance Valves are designed for maximum efficiency, withstanding the extreme conditions of a turbo diesel engine. Exhaust valves use an Inconel 751 head and intake valves have 21-N4 stainless steel heads. Both intake and exhaust valves employ a mid stem "friction weld."

All Black Lightning Diesel Performance Valves have a hardened tip and a black nitride finish to the entire valve, including the top of the valve. The seat face remains precision machined.
