  • About This Product
  • Reviews


The most common problem with a Bosch alternator in the '03-'07 Dodge Cummins Turbo Diesel truck equipped with the 5.9L engine is that the brushes wear out. Without good brush-to-armature contact the electrical charge to the battery is weak and you'll find your truck has dim lights and a weak or dead battery.

The rebuild kit includes:

  • Armature brushes
  • (2) bearings
Some truck owners replace the Bosch alternator. Budget conscious owners rebuild the alternator with new brushes and bearings prior to complete failure.

Many just buy a new alternator and the smart ones replace the wearable parts. This was a simple and easy fix. Package was nice and simple, on time and I got my free decal. I owe Robin a big thank you for always providing great customer service even when something on my end falls through. It's hard to find consistency in customer service. Genos staff regardless of the associate, are ALL understanding of what true customer service is. Whether it is installing a product and having them spend time troubleshooting it with me, or providing warranty replacements without a fuss or hassle. There's a reason why I continue to buy from Genos and will for the duration of owning my cummins. Big thanks to everyone that makes a great company possible.
Owner Response:Thank you for the kind words. Your business is truly appreciated.

Great Kit

Easy rebuild. The only issue was locating a puller for the clutch pulley. It would be great if you sold that as well.
