Leroy Diesel Billet Crankshaft Pulley

Description

Billet Crankshaft Pulley for 6.5 diesels w/serp belt systems (6 groove).

This pulley is 2.5 pounds lighter, made from billet aluminum, and does away with the problems of the factory pulleys. It is anodized to protect the surface.  Will fit all 6.5 diesels with the serpentine belt system with 6 groove belt as found on all civilian Hummer/H1 vehicles.

This is a lifetime part you will not need to change ever again.

The stock pulleys are known to crack/separate and fail quite often.  After the stock pulley has failed, it can sound like a rod knock. Be sure to inspect your 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, replace it soon!
