Billet Crankshaft Pulley for military Humvee 6.5 diesels w/serpentine belt, 24 volt systems (8 groove).
Attention: This is not for 6 groove applications (civilian Hummer) if you need the 6 groove pulley see this listing.
This pulley is 2.5 pounds lighter and made from a billet block of aluminum and finally does away with the problems the factory pulleys have. It is anodized to protect it. Will fit 6.5 diesels with the 8 groove serp belt system.
This is a lifetime part you will not need to change it ever again.
If you have had a 6.5 diesel for anytime you know all about the factory pulley problems, this will fix it for good.
The stock pulleys are known to crack/separate and fail quite often. The stock pulley after it has failed can sound like a rod knock. Be sure to inspect you old pulley every oil change if you see any sign of the rubber cracking or dry rot or if you can move the outside ring independent of the hub then replace it immediately!
