Elk Grove Dodge Chrysler Jeep RAM
Elk Grove Dodge Chrysler Jeep Ram · Ram 3500 Research
Dual rear wheels change more than the look of a Ram 3500. They change the axle rating, the gross vehicle weight rating and the towing chart, and they make the truck 13 in wider. Here is the full comparison, configuration by configuration.
| Cab and bed | Single rear wheel | Dually | Drive |
|---|---|---|---|
| Regular Cab, 8-ft bed | Yes | Yes | 4x2 or 4x4 |
| Crew Cab, 6-ft 4-in bed | Yes | No | 4x2 or 4x4 |
| Crew Cab, 8-ft bed | Yes | Yes | 4x2 or 4x4 |
| Mega Cab, 6-ft 4-in bed | Yes | Yes | 4x4 only |
If you want a Crew Cab with the short bed, it's a single-rear-wheel truck. The Mega Cab comes on Laramie, Limited and Limited Longhorn, and Ram's towing chart lists it with the Cummins. Dually availability by trim can vary, so ask us to check the order guide for the trim you want.
| Single rear wheel | Dually | |
|---|---|---|
| Overall width | 83.5 in | 96.5 in |
| Rear track | 67.1 in | 75.9 in |
| Rear axle rating (GAWR) | 7,000 lb | 9,750 lb |
| GVWR | 11,040 to 12,300 lb | 14,000 lb |
| GCWR, Cummins | 31,820 to 34,420 lb | 41,950 to 45,000 lb |
| GCWR, HEMI | 22,000 to 24,240 lb | 22,600 or 25,000 lb |
| Rear tires | 2 | 4 |
The rear track is 8.8 in wider on a dually, and the extra pair of rear tires spreads the load. That's where the 2,750-lb jump in rear axle rating comes from, and it's why the dually is the steadier platform when a fifth-wheel or gooseneck puts its weight right over the rear axle.
With the 6.7L Cummins High Output, the difference is large. Ram's preliminary 2027 ratings, same cab, bed and drivetrain:
| Configuration (Cummins HO, 3.42 axle) | Single rear wheel | Dually | Difference |
|---|---|---|---|
| 4x2 Regular Cab 8-ft | 26,940 lb | 37,020 lb | +10,080 lb |
| 4x4 Regular Cab 8-ft | 26,080 lb | 36,610 lb | +10,530 lb |
| 4x2 Crew Cab 8-ft | 25,490 lb | 34,490 lb | +9,000 lb |
| 4x4 Crew Cab 8-ft | 25,180 lb | 33,560 lb | +8,380 lb |
| 4x4 Mega Cab 6-ft 4-in | 24,080 lb | 32,890 lb | +8,810 lb |
With the 6.4L HEMI, the dually barely moves the towing number, because the gas engine's combined weight rating is the limit, not the axle:
| Configuration (HEMI, 4.10 axle) | Single rear wheel | Dually | Difference |
|---|---|---|---|
| 4x2 Regular Cab 8-ft | 17,730 lb | 18,140 lb | +410 lb |
| 4x4 Regular Cab 8-ft | 17,330 lb | 17,760 lb | +430 lb |
| 4x2 Crew Cab 8-ft | 17,170 lb | 17,550 lb | +380 lb |
| 4x4 Crew Cab 8-ft | 16,800 lb | 17,180 lb | +380 lb |
The 37,020-lb rating is the 4x2 Regular Cab 8-ft dually with the Cummins and 3.42 axle; the 36,610-lb rating is the same truck with 4x4. See every row on our 2027 Ram 3500 towing chart.
The takeaway: a HEMI dually makes sense for payload, not towing. It carries up to 7,580 lb as a 4x2 Regular Cab, the most of any 2027 Ram 3500.
Thirteen extra inches of width shows up in daily driving more than on the spec sheet. A few things to check before you commit:
| If you... | Consider |
|---|---|
| Tow a fifth-wheel or gooseneck above the SRW rating for your cab | Dually, Cummins |
| Want maximum payload for a slide-in camper or materials | Dually, often HEMI |
| Tow a travel trailer or boat and need a short-bed Crew Cab | Single rear wheel |
| Park in a home garage or city lots every day | Single rear wheel |
If your trailer fits within a single-rear-wheel 3500's rating with margin, you may not need the 1-ton at all. Our Ram 2500 vs 3500 guide covers that step.
96.5 in, versus 83.5 in for a single-rear-wheel Ram 3500. The rear track is 75.9 in on the dually and 67.1 in on the SRW truck.
No. The Crew Cab with the 6-ft 4-in bed comes with single rear wheels only. Duallys are offered as a Regular Cab 8-ft, Crew Cab 8-ft or Mega Cab 6-ft 4-in.
With the Cummins, about 8,400 to 10,500 lb more than the same single-rear-wheel truck, based on Ram's preliminary 2027 ratings. With the HEMI, the gain is a few hundred pounds.
14,000 lb on every dually configuration. Single-rear-wheel Ram 3500s range from 11,040 to 12,300 lb.
The rear GAWR is 9,750 lb on a dually and 7,000 lb on a single-rear-wheel truck.
Measure the door opening first. At 96.5 in wide before mirrors, a dually is a tight fit or no fit for many home garages.
Yes. The 37,020-lb maximum is a 4x2 Regular Cab 8-ft dually with the Cummins and 3.42 axle, and the same truck with 4x4 is rated at 36,610 lb.
