QualCast has introduced two new valve train kit lines for 2021. One is for heavy-duty and the other is the QualFast Black Lightening Diesel Performance kits. Both the heavy-duty kits and the Black Lightning kits allow customers to order one part number and receive one box with all of the valvetrain components to complete their cylinder head build.
“These kits save our customers valuable time in ordering and part research. Customers are able to place one phone call or send one email and order one part number today and have all the valve train pieces tomorrow to finish their job. QualCast valve train and valve kits, one part number, one call equals a complete head,” says Paul Hauglie, national sales manager for QualCast.

Heavy Duty Valve Train Kits include: Valves, Valve Guides, Valve Keepers, Valve Stem Seals, Valve Springs, Injector Tubes, and o-rings (if needed). Coverage includes the popular HD applications for Caterpillar, Detroit Diesel, Volvo Heavy Duty, Cummins and Ford Navistar.
QualFast Black Lightning Diesel Performance Valve Kits include: Black Lightning Diesel Performance Valves, Drop-in Diesel Performance Valve Springs, Top Hat Style Valve Stem Seals, Valve Spring Retainers, and Valve Keepers. These kits cover the popular diesel performance engines: Cummins 5.9L 12v & 24v, Duramax 6.6L 32v & Powerstroke 6.0L, 6.4L & 6.7L.
