2016 Ram 3500 Lets You Tow an Even Bigger House - Car and Driver (blog)

For 2016, the Ram 3500 is rated to tow a monstrous 31,210 pounds, 1210 pounds more than the 2015 Ram 3500 and a mere 10 pounds more than Ford’s F-450 pickup, the tow rating of which stands at “just” 31,200 pounds. The Ram’s increase was made possible in part by upping the number of bolts on the rear-axle ring-gear hardware (from 12 to 16, if you must know) on versions equipped with the 11. 8-inch rear axle, as well as by using a stronger differential-case... Also helping matters is a 35 lb-ft increase in torque for the 6. 7-liter Cummins inline-six diesel engine, bringing the total to a nice, even 900 lb-ft (also bragging-rights material). The latter boost was made possible by recalibrated fuel-delivery and turbo-boost settings, Ram says. Ram is also boasting the highest payload for a pickup: 7390 pounds for the 2016 Ram 3500 equipped with the 6. 4-liter Hemi V-8. All claims are made using SAE J2807 testing criteria, which we explain in detail here. Source: blog.caranddriver.com
