FAQ
Does this pulley fit both 5.9L and 6.7L Cummins engines?
Yes. The FPE-34660-AL is designed as a direct replacement fan drive pulley for 2003–2012 Ram 2500/3500 trucks equipped with either the 5.9L or 6.7L common-rail Cummins, as long as they retain the factory-style fan drive layout.
Is this a direct replacement for the factory Mopar pulley?
Yes. This billet aluminum pulley is a direct replacement for OE part number 4930580 and keeps the stock belt alignment and fan drive geometry so you can bolt it on without modifying brackets or belt routing.
Do I need to change my fan clutch or belt when installing this pulley?
In most cases, you can reuse your existing fan clutch and belt as long as they are in good condition. Many owners choose to replace a worn belt or fan clutch during the install since everything is already apart, but it’s not required strictly for pulley fitment.
Can the bare aluminum finish be painted or powder coated?
Yes. The bare billet aluminum finish can be polished, painted, or powder coated if you want to color-match other engine dress-up parts. Just follow proper surface prep and coating procedures recommended by your coating supplier.
Will this pulley affect cooling performance?
The FPE-34660-AL maintains the factory pulley diameter (6.965" OD), so fan speed and cooling characteristics remain consistent with stock while providing the strength and appearance benefits of billet aluminum.
