The Cummins K19 / KTA19 Cylinder Head — part number 3811985 is a genuine Cummins part, supplied at £600 by G Service Power. It is reconditioned, held in UK stock and dispatched next day, worldwide.
Reconditioned Cummins cylinder head, part number 3811985, supplied under the Cummins ReCon exchange number RX3811985. The cylinder head seals the top of the cylinder bore and carries the inlet and exhaust valves, valve springs, injector bore and the coolant and oil galleries, so it is the part replaced when a head cracks, warps, fails a pressure test or suffers valve-seat damage — a common job on high-hour K-series engines. This head has been fully remanufactured to Cummins specification: disassembled, cleaned, inspected and rebuilt ready to fit, and reconditioned in 2016–2017 per the label. The casting on this unit is stamped 3081064-01 and marked INDIA (see photos); Cummins casting numbers vary between production batches, so match on the 3811985 part number rather than the casting. Fits Cummins K19, KT19, KTA19 and QSK19 series engines as used in industrial, generator, marine and truck applications. Please verify compatibility against your engine serial number before ordering.
