Thanks to an upgraded cooling system — optional in 2015 — some 2016 Ram 1500 diesels have increased their ability to tow.
The rating was quietly changed on the Ram web site and noticed by reader Sean Marzola, then confirmed by a Ram spokesman, along with the explanation. The 2016 Ram diesel 4x4, Crew Cab, with a five foot, seven inch bed is rated at towing up to 8,400 pounds with 3.92:1 gearing, substantially higher than in the 2015s.
The maximum towing capacity of the Ram 1500 diesel, in its optimal towing configuration, remains at 9,200 pounds.
