3801903 Cylinder Head Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head for the D8 range, weighing 130 kg and listed for eight applications across the D8A1-A to D8A6-A MP, MH and MG engines. Reman cylinder heads are supplied ready for installation with the valves and springs already fitted, and with camshaft-bearing housings included where the design has them. Volvo Penta's reman catalogue carries a specific caution against this head: check the web shop or your dealer for serial number compatibility before ordering, because the D8 head is not interchangeable across the whole build range. Supplied on exchange, so a core fee is added to the invoice and refunded when the worn head is returned.
