03-17 5.9L/6.7L Cummins Billet Aluminum Fan Pulley

03-18 5.9L/6.7L Cummins Billet Aluminum Fan Pulley




This is a billet fan pulley that is a smaller diameter than the stock OEM fan pulley. This allows you to change the belt without removing the fan pulley if you have an aftermarket harmonic balancer, and it looks really cool/badass. 

This piece is smaller compared to the stock pulley, about 1/2 inch.

Will work for 2003 and up 5.9L & 6.7L Cummins diesels.

  • Manufactured from a solid piece of billet aluminum

A shorter belt MAY be required for 03-12 5.9L Cummins diesel trucks, this will depend on the belt tensioner being used.  We have installed several of these on 13-18 trucks without a belt change.  The number of the belt we've used in house is 5081244.
