2021 Ram HD Retakes Torque Crown From Ford Super Duty

The heavy-duty, diesel-powered truck wars are a constant game of leapfrog from one manufacturer to the next. With each passing refresh, we see either Ford, Chevrolet, or Ram retake the torque and/or towing and payload crowns from another in an endless cycle of one-upmanship. And now, it has happened again. The Ford Super Duty, which previously offered the most torque in its class, has been beaten out by the 2021 Ram HD.

The 2021 Ram HD 3500 equipped with the 6.7L Cummins turbo-diesel inline-six produces 1,075 pound-feet of torque – 75 more than the previous model, and 25 more than the Ford 6.7L Power Stroke available in the Ford Super Duty. Ram and Cummins accomplished that jump in torque thanks to higher boost limits from a variable geometry turbocharger and flow rate increases in the fuel delivery system.

In addition to retaking the lead in the diesel torque department, the 2021 Ram HD also offers a segment-leading 37,100 pounds of towing capability when equipped with a new fifth wheel and gooseneck hitch that were designed in-house and are integrated into the production box floor. To help support that weight, the rear portion of the frame includes fully boxed rails and the rear-axle structural crossmember.

Additionally, the standard 4/7-pin trailer connector at the bumper and an additional 7-pin connector are integrated into the rear of the bed to easily wire a trailer. Using a conventional hitch, the maximum trailer weight rating comes in at 23,000 pounds.

Also new for 2021, the Ram Heavy Duty features a digital rearview mirror that displays video in real-time from a rear-facing camera and can be turned off to revert back to a traditional reflective mirror. The digital rearview mirror is available on all Heavy Duty models.

The first 2021 Ram Heavy Duty high-output pickup trucks are scheduled to begin rolling off the production line this month.

Brett's lost track of all the Fords he's owned over the years and how much he's spent modifying them, but his current money pits include an S550 Mustang and 13th gen F-150.

    It’s getting to a point that it’s getting harder to believe these numbers from any manufacturer. Never towed 35000 pounds but wonder how safe in vehicle that size would it be. And also how long that engine would actually last if you constantly are towing that kind of weight?

    Ford should just crank it up yo 1200ft lbs and be done with it. In the other hand, if anyone tows a 37,000 lb trailer with such a light truck, they’re fools. It’s getting a bit dangerous. To think some rich kid, I know 2 who have, bought one of these dually’s and could technically tow a massive trailer without any experience, is so dangerous to them and anyone around them. Not just a rich kid but an adult who’s first truck is one of these beasts. But 1000+ ft lbs is unreal, from the factory with a warranty

      past a certain weight point you do need a CDL. Most of these are well past CDL class. I think the cuttoff if 30,000lbs truck and trailer COMBINED. 3500’s weigh in at over 8000lbs already.

        In my state, at least, CDL restrictions are based on GVWR, not GCWR. So even these F-450s and heavy 3500s with a GVWR of 14K (remember, the F-450 pickup is not in the same class as the F-450 chassis) still don’t need a CDL since they’re below 26K.

        But yes, the GCWR on a lot of these tow-pig Class 3s is often way up in the 30-40K range. When the Super Duty first came out, the heaviest F-350 pickups (not chassis) had a GCWR of 20K, GVWR of 11K, and tow rating of 14K.
