- Ram comes in first, claiming a maximum tow rating of 37,100 lb on the 3500
- Following closely behind is Ford, claiming a maximum tow rating of 37,000 lb on the F-450
- Rounding out the list is GMC’s 3500 with a claimed maximum tow rating of 36,000 lb
However, there is a bit of smoke and mirrors involved here. While the numbers are genuine, each of these top numbers is achieved by just one version of each of these trucks. In each case, regardless of manufacturer, the maximum tow rating applies to a regular cab, base model trim, dual rear wheel, 4×2 truck. In other words, a truck that very few will ever buy. If you build the most popular truck – a crew cab, 4×4, mid-level trim package – the average weight goes down. If there is a cautionary tale here, it’s to never take that maximum tow rating number to heart. Build your truck first and then find out what its exact payload and tow numbers are.
For each of the HD builders we’ve compiled a list of what’s new on the trucks for 2021 – current weight ratings and the most recent noteworthy updates. Here they are:
2021 Ford | F-250, F-350 and F-450
In 2020 Super Duty announced an all-new gas engine – the 7.3L V8. This addition gave HD customers two gas engine choices. The standard 6.2L V8 and now the 7.3L V8 – both are paired with new 10-speed automatic designed specifically for HD transmissions. The new 7.3L gas V8 design is built on decades of Ford’s commercial engine experience, meant to provide durability, ease of maintenance, and the towing and payload capability customers want. As for the diesel option – the 6.7L Power Stroke is now in its third generation; it too is paired with the 10-speed TorqShift automatic.
