2026 RAM Heavy Duty Towing Guide: How Much Can Each Trim Tow?

TL;DR:

While many buyers assume trim level is the biggest factor affecting RAM towing capacity, the reality is that a truck’s configuration has a much greater impact. In this guide, you’ll learn how engine choice, cab configuration, axle ratio, and rear-wheel setup influence towing capability across the 2026 RAM Heavy Duty lineup, helping you choose the right RAM 2500 or RAM 3500 for your needs.

• The highest-rated 2026 RAM 2500 can tow up to 20,000 lbs, while the top-rated RAM 3500 can tow up to 36,610 lbs.
• The available 6.7L Cummins® High-Output Turbo Diesel delivers significantly higher towing capacity than the standard 6.4L HEMI® V8.
• A dual-rear-wheel (DRW) RAM 3500 can tow more than 10,000 lbs more than certain single-rear-wheel configurations.
• Regular Cab, Crew Cab, and Mega Cab configurations all affect towing capacity due to differences in vehicle weight.
• Axle ratio plays a major role in towing performance and can increase towing capacity by several thousand pounds depending on the configuration.

Wondering if choosing between one RAM trim level versus another matters when it comes to the effect it has on towing capacity? While technically, the answer is yes, it’s not for the reasons you think.

If by trim level you are referring to the difference between the RAM 1500 towing capacity, the RAM 2500 towing capacity, and the RAM 3500 towing capacity, then there’s absolutely a difference. If however, you’re comparing true trim levels across one particular RAM weight class like the 2500 or 3500, then you might be surprised to find out that towing capacity differences may not vary as much as you think.

But wait. That does not mean that across a weight class, meaningful differences between towing capabilities are not present. The reverse is true. It’s just that the factors that influence differences in RAM towing capacity that matter are:

• Engine choice
• Single-rear-wheel vs. dual-rear-wheel configuration
• Cab configuration
• Bed length
• Axle ratio

Let’s break this down further, so you know exactly which RAM model in which configuration meets your towing needs.

Things That Impact RAM Towing Capacity

Many shoppers focus on trim levels when comparing RAM Heavy Duty trucks, but trims are only one piece of the puzzle. True, higher trims may add certain features that slightly affect a truck’s weight and towing capacity.

But by far the biggest differences in towing capacity come from the truck’s configuration. Engine choice, rear-wheel setup, cab size, and axle ratio can change towing capacity by thousands of pounds, making them far more important considerations when shopping for a RAM 2500 or RAM 3500.

Engine Choice

The engine has the biggest impact on towing capacity throughout the RAM Heavy Duty lineup.

The available 6.7L Cummins® High-Output Turbo Diesel significantly outperforms the standard 6.4L HEMI® V8 when maximum towing is the goal.

RAM 2500 vs 3500

Choosing between a RAM 2500 and RAM 3500 can dramatically affect towing capability.

While the RAM 2500 offers impressive towing performance for recreational users and contractors, the RAM 3500 is engineered for heavier loads and higher gross vehicle weight ratings (GVWRs).

As a result, properly equipped RAM 3500 models can tow substantially more than their RAM 2500 counterparts.

Single Rear Wheel vs Dual Rear Wheel Configuration

One of the biggest towing upgrades available on a RAM 3500 is the move from a single-rear-wheel (SRW) setup to a dual-rear-wheel (DRW) configuration.

Dual rear wheels provide:

• Increased towing capacity
• Greater trailer stability
• Improved weight distribution
• Better control when towing large fifth-wheel or gooseneck trailers

For drivers towing extremely heavy loads, a dually configuration can increase towing capacity by more than 10,000 pounds compared to some single-rear-wheel models.

Cab Configuration

Cab size also affects towing capacity because larger cabs add weight to the truck.

Generally speaking:

• Regular Cab models offer the highest towing ratings
• Crew Cab models provide a balance of towing capability and passenger space
• Mega Cab models maximize interior room but may sacrifice some towing capacity

For many buyers, the differences are relatively small, but they can become important when towing near a truck’s maximum rating.

Axle Ratio

Axle ratio is one of the most overlooked factors affecting towing capacity.

A numerically higher axle ratio allows the truck to transfer power more effectively when towing heavy loads. In some RAM HD configurations, changing the axle ratio can increase towing capacity by several thousand pounds.

Drivers who tow frequently should pay close attention to axle ratio specifications when comparing trucks, as this single option can have a significant impact on overall towing performance.
