A couple of Ram guys were trying to convince me of how reliable their trucks were. I told them the reason they weren't too bad was because the major components were made by Cummins, Dana, and Allison replacing the Chrysler/Fiat junk. After objecting, one Ram guy turned to the other and confessed "You know, he's got a point. I only bought the Ram because of the Cummins."
That’s why my rollback (tow truck) is allowed to be a GM. It’s powered by cat. Shifted by Alison. Stopped by bendex and axles are Eaton.
The GM parts are falling apart though.
The Ram trucks have Aisin or 68RFE transmissions. American axles. 2002 was last year they had Dana. Had the Cummins powered trucks since 1995. Been very reliable trucks.
