About this part
The Cummins K19 / KTA19 Cylinder Head — part number 3811985 is a genuine Cummins part, supplied at $800 by G Service Power. It is reconditioned, held in UK stock and shipped to the USA by DHL Express or UPS Express, dispatched the next business day.
Cummins ReCon reconditioned cylinder head for the K19 family (KTA19, KT19, K19), part number 3811985, supplied as RX3811985, available to ship to the USA for $800 each with 4 or more in stock. Why it matters in the US: Cummins has superseded 3811985 through 3640321 and 3646324 to 5581368, and no longer sells that head new; the only form Cummins lists today is the ReCon exchange head 5581368RX. So if your parts book or dealer gives you any number in that chain, this is the same head. This unit is a Cummins ReCon head: the label reads RX3811985, Reconditioned head cylinder, dated 17 March 2017, and it is supplied assembled with its valves and springs fitted. The casting is 3081064-01, marked INDIA; casting numbers vary between batches, so match on the part number, not the casting. Fitment: the late-type KT/KTA head used six per engine on the KTA19 and shared across the K-family KTA38 (V12) and KTA50 (V16), engines used in mining, oilfield, marine and generator set work. It is not the early KT head (3007207, 3050491, 3801073 and similar), and some QSK19 CPLs take a different head, so check your CPL or engine serial number. Sold outright, with no core to return, unlike a dealer ReCon exchange. Shipping one head to the USA is $225 by DHL Express or UPS Express, 3–5 business days after dispatch (Cummins lists the shipping weight at about 68 lb); freight for several heads is quoted to your ZIP code. Call or WhatsApp +44 7951 632187, or email info@gservicepower.com with the quantity and your ZIP code.
Compatibility: fits Cummins KTA19 / KT19 / K19, KTA38 / KT38 and KTA50 / KT50 — the full list of engines and interchangeable part numbers is on the . Confirm against your engine serial number before ordering, or call us and we will check it with you.
