What's new for 2027: Ram Heavy Duty trucks get a capability and packaging update, not a redesign. Stellantis Canada's July 27, 2026 release adds more GVWR and payload on specific Ram 3500 builds, beadlock capable wheels and a standalone Warn winch for the gas Power Wagon, appearance packages on more equipment groups and two new colours, and a separate release puts the 6.7 litre Cummins High Output turbo diesel in the Power Wagon for the first time. Our new Ram 3500 inventory and new Ram 2500 inventory show what is on the ground today.
The release lists no engine or transmission change, so the 2027 question is whether one of these changes is on your list. Our post on the 2027 Ram Power Wagon with the Cummins diesel covers that truck on its own; below is the whole lineup, written for buyers anywhere in Manitoba by Dunn Ram Trucks in Portage la Prairie.
Key Takeaways
- Not a redesign. Stellantis Canada's July 27, 2026 release lists no engine or transmission change: the 6.4 litre HEMI V8 is rated at 410 horsepower and 429 lb ft, and the 6.7 litre Cummins High Output turbo diesel at 430 horsepower and 1,075 lb ft, each with an eight speed automatic.
- Ram 3500 payload. Ram 3500 4x4 single rear wheel trucks with the 6.4 litre HEMI V8, in the Regular Cab 8 foot box and Crew Cab 6 foot 4 inch box, now offer a maximum GVWR of 5,189 kg (11,440 lb), up 181 kg (400 lb) in GVWR and payload over 2026.
- Power Wagon. A separate Stellantis Canada release offers the 2027 Power Wagon with the 6.7 litre Cummins High Output turbo diesel for the first time.
- Options open up. A beadlock capable wheel package for the Power Wagon with the 6.4 litre HEMI V8, a standalone Warn winch on Rebel and Power Wagon with that engine, and Sport Appearance and Night Edition on Level 1 and Level 2 equipment groups.
- Warranty. A 2027 Ram 2500 or 3500 carries Ram Canada's standard warranty: 3 years or 60,000 km basic, 5 years or 100,000 km limited powertrain, and a separate 5 year or 160,000 km Cummins engine warranty on diesels.
What Changed for the 2027 Ram Heavy Duty
Every change in this table comes from Stellantis Canada's July 27, 2026 release and its 2027 Ram Heavy Duty press kit, except the diesel Power Wagon, which has its own Stellantis Canada release.

The Power Wagon gets the diesel. Stellantis Canada's release on the 2027 Ram Power Wagon with the 6.7 litre Cummins High Output turbo diesel gives 430 horsepower and 1,075 lb ft, a tow rating of nearly 9,072 kg (20,000 lb) and a payload capacity of almost 1,360 kg (3,000 lb). It lists front and rear electronic locking differentials, Bilstein shocks, a disconnecting front stabilizer bar and available fifth wheel and gooseneck prep, with arrival in the second half of 2026. The heavy duty release ties the standalone winch to the 6.4 litre HEMI V8, so ask our team what the order guide allows on a diesel Power Wagon.
Is the 2027 Ram 2500 a Redesign?
No. Stellantis Canada describes the 2027 Ram Heavy Duty in terms of new packages, options and capability changes and does not call it a redesign, and its release lists no engine or transmission change. The 6.4 litre HEMI V8 is rated at 410 horsepower and 429 lb ft with a TorqueFlite eight speed automatic, and the 6.7 litre Cummins High Output turbo diesel at 430 horsepower and 1,075 lb ft with a TorqueFlite HD eight speed automatic. The release lists nine trims: Tradesman, Black Express, Warlock, Big Horn, Laramie, Rebel, Power Wagon, Limited and Limited Longhorn.
If you are deciding between a three quarter ton and a one ton, our Ram 2500 versus 3500 breakdown walks through the choice.
What's New on the 2027 Ram 3500
Ram 3500 4x4 single rear wheel trucks with the 6.4 litre HEMI V8, in the Regular Cab 8 foot box and the Crew Cab 6 foot 4 inch box, now offer a maximum GVWR of 5,189 kg (11,440 lb). Stellantis Canada says that raises GVWR and payload capability by 181 kg (400 lb) over 2026.
Two limits apply. It covers those two configurations with the 6.4 litre HEMI V8, not every 3500, and it is a maximum, so the rating that counts is the one on your own truck's door label. If you are weighing a single rear wheel 3500 against a dually, our dually versus single rear wheel post covers that choice.
The 2027 Numbers That Decide the Truck
These are Stellantis Canada's 2027 maximums by model and engine. Every one depends on cab, box, axle and equipment, so confirm the figure for your exact build on its window sticker and door label before you sign.
Ram 2500 with the 6.4 litre HEMI V8. Tows up to 8,047 kg (17,740 lb) and carries up to 2,077 kg (4,580 lb) of payload.
Ram 2500 with the 6.7 litre Cummins High Output turbo diesel. Tows up to 9,072 kg (20,000 lb) and carries up to 1,810 kg (3,990 lb).
Ram 3500 with the 6.4 litre HEMI V8. Tows up to 8,228 kg (18,140 lb) and carries up to 3,438 kg (7,580 lb).
Ram 3500 with the 6.7 litre Cummins High Output turbo diesel. Tows up to 16,792 kg (37,020 lb) and carries up to 2,930 kg (6,460 lb).
On both models the 6.7 litre Cummins High Output turbo diesel has the higher maximum towing and the 6.4 litre HEMI V8 the higher maximum payload, so the right engine depends on whether your weight rides behind the truck or in it. Our Ram 2500 diesel versus gas post works through that choice.
Warranty on a 2027 Ram Heavy Duty
A 2027 Ram 2500 or 3500 carries Ram Canada's standard warranty: 3 years or 60,000 km basic, 5 years or 100,000 km fully transferable limited powertrain with a $0 deductible, and 24 hour roadside assistance. Trucks with the 6.7 litre Cummins High Output turbo diesel add a separate 5 year or 160,000 km Cummins engine warranty.
That is worth knowing if you are comparing against a new 2026. A 2026 model year Ram 2500 or 3500 bought or leased new by a retail customer carries Ram Canada's 10 year or 160,000 km limited powertrain warranty, whichever comes first; it is for the 2026 model year only, not offered to fleet customers, and not transferable except where provincial law requires.
Which Changes Matter in Manitoba
Here is how each change lands for a farm, a trade or an acreage, from the Portage la Prairie ring to Westman and the Interlake.
The Ram 3500 GVWR increase is the sleeper. It matters to the buyer carrying weight in and on the truck rather than behind it: a slide in camper headed to Lake Manitoba, a welding deck, or a fuel tank and toolboxes at seeding. On a single rear wheel truck, 181 kg (400 lb) more rated capacity can be the margin between a load inside the rating and one over it. If that is your use, a 2027 in one of those two configurations is the better fit.
The standalone winch is a rural win. On a farm a winch is how a truck comes out of a drifted field approach or a soft headland without waiting for a second vehicle. Not having to buy the Level 1 Equipment Group to get one makes that decision simpler.
The diesel Power Wagon closes a gap. It suits the buyer who wants the Power Wagon's locking differentials for grid roads and trails and a diesel for pulling a camper or a stock trailer.
The package shuffle is styling, not capability. Night Edition and Sport Appearance on the lower equipment groups mean the blacked out look no longer forces you up the ladder. The colours and the badge change nothing about how the truck works.
Order a 2027 or buy a 2026? If your work needs one of the changes above, order a 2027. If not, a new 2026, if one is still available in your build, gives you the same two engines and the longer 2026 model year limited powertrain coverage described above. Browse our full new inventory, see which trucks this month's offers cover on our Ram finance deals page, and ask our team whether a 2026 in your configuration is still available.
If your current truck is going toward the new one, we honour the instant cash offer: the number you get online is the number we stand behind when the vehicle matches what you told us, so get your instant cash offer first. When you are ready, apply for financing; any rate or term is on approved credit.
FAQs
What's new for the 2027 Ram Heavy Duty in Canada?
An update year, not a redesign.

The Ram 2500 changes are options and packages, led by the first Power Wagon offered with the Cummins diesel.
What changed on the 2027 Ram 3500?
Ram 3500 4x4 single rear wheel trucks with the 6.4 litre HEMI V8, in the Regular Cab 8 foot box and Crew Cab 6 foot 4 inch box, now offer a maximum GVWR of 5,189 kg (11,440 lb), an increase in GVWR and payload of 181 kg (400 lb) over 2026, according to Stellantis Canada.

What warranty does a 2027 Ram 2500 or 3500 carry?
Ram Canada's standard warranty: 3 years or 60,000 km basic, 5 years or 100,000 km fully transferable limited powertrain with a $0 deductible, and 24 hour roadside assistance. Trucks with the 6.7 litre Cummins High Output turbo diesel add a separate 5 year or 160,000 km Cummins engine warranty.
Should I order a 2027 Ram Heavy Duty or buy a 2026?
Order a 2027 if you need one of its changes, such as the Ram 3500 GVWR increase or the diesel Power Wagon. Otherwise compare it with a new 2026 if one is still available in your build: a 2026 model year Ram 2500 or 3500 bought or leased new by a retail customer carries Ram Canada's 10 year or 160,000 km limited powertrain warranty, whichever comes first, for the 2026 model year only, not offered to fleet customers and not transferable except where provincial law requires.
The Bottom Line
The 2027 Ram Heavy Duty is an update where a working truck feels it: more rated payload on two Ram 3500 configurations with the 6.4 litre HEMI V8, a Power Wagon you can finally get with the 6.7 litre Cummins High Output turbo diesel, and easier access to the winch and the blacked out look. Order a 2027 if one of those is on your must have list; otherwise compare it with a new 2026 if one is still available. Once the truck is working, our service department does oil and filter changes, gas and diesel, so book your oil change with our service team.
