This is a billet aluminum Serpentine belt pulley for the D4 and D6 raw water pumps. It replaces the OEM #3583599 pulley which is cast aluminum and prone to cracking upon removal.
*Pump in picture is not included and is just for reference.
I also have the following available in my eBay store.
- D4 Rebuilt pumps
- D6 Rebuilt pumps
- New D4 and D6 pumps
- Kits for D4 and D6
