What Is Trailer Tow Group IV? All You Need To Know!

When you dive into the world of towing, knowing what your gear can handle is a must. 

Whether you’re gearing up to haul a camper, a boat, or some hefty cargo, getting your setup right is key. 

In this rundown of the Trailer Tow Group IV, I’ll tell you how much weight you can pull with this package, and what different hitch types mean.

What Is Trailer Tow Group IV?

The Trailer Tow Group IV, also known as the “max tow” package, is like a power-up for vehicles that need to tow heavy stuff. This package can include a stronger hitch, better cooling systems, tougher suspension, and smarter electrical connections.

Yep, it’s not just about a fancy hitch – it’s a whole package that makes towing easier. 

This package is usually available for models like the Jeep Grand Cherokee and Dodge Durango.  

What Does Trailer Tow Group IV Include?

Here’s a more specific list of what you can get:

  • NHAP heavy-duty engine oil cooler.
  • 180-amp or 220-amp alternator (depends on how much power your vehicle needs for different uses.).
  • Rear load-leveling suspension (please note it’s not available with quadra-lift air suspension system).
  • Full-size spare tire.
  • Steel spare wheel.
  • Class IV receiver hitch with seven- and four-pin wiring harness.
  • Delete rear tow hook.

How Much Can A Class IV Trailer Hitch Tow?

A Class IV Trailer Hitch Tow can give you plenty of load capabilities. The maximum capacity of Class IV, according to J.D Power, is about 10,000 pounds.

For example, a Dodge Durango GT with the Trailer Tow Group IV can tow around 8,400 pounds. Some vehicles equipped with it can tow even more than that.

That means you can confidently tow things like medium-sized trailers or boats without any problems. 

How Do I Know If I Have A Class IV Hitch?

Figuring out what hitch your vehicle has is simple. 

Take the Ford F-150 for example. It often comes with a Class IV hitch, which has a square hole that’s 2 inches by 2 inches. 

But here’s the thing – what your hitch can do might change based on the model and year of your vehicle. 

This square hole is where you can attach all sorts of towing equipment. 

What Is The Difference Between A Class V And Class IV Trailer Hitch?

A Class V hitch is the heavyweight champ, able to handle even more weight than its Class IV counterpart. 

While a Class IV can do 10,000 pounds, a Class V hitch can step it up even further, often towing up to 20,000 pounds. 

If you’re planning some heavy-duty towing, the Class V hitch is your go-to. I’ve used it myself, but not to the full extent; the most towing power I needed was 18,000 pounds. 

Vehicles like the Ford Expedition or the Chevrolet Suburban might have a Class V hitch- they’re built for even heavier loads.

What Is The Difference Between A Class III And Class IV Trailer Hitch?

Class III and Class IV trailer hitches are designed for different towing needs. 

A Class III hitch is generally rated for lighter loads, around 5,000 pounds, and often features a 2-inch by 2-inch receiver. 

On the other hand, as we mentioned, a Class IV hitch can handle heavier loads, up to 10,000 to 12,000 pounds, making it suitable for larger trailers and more substantial towing tasks. 

Always match the hitch class with your towing requirements for safety and efficiency.


What is the towing capacity of a Jeep Grand Cherokee?

What is trailer tow Group IV Dodge Durango?

It’s a special package for the Durango. It adds things like a strong hitch, a trailer brake switch, and more. With the 5.7L HEMI V8 engine, it tows up to 8,700 lbs.

What is Ram Trailer Tow Group?

It’s an upgrade package for the Ram 1500. It includes a hitch, towing mirrors, and a brake controller. The numbers change based on the engine and cab style.

Final Thoughts

When you’re towing, you’ve got to understand trailer hitches and towing limits. 

Whether you’re behind the wheel of a beefy Jeep Grand Cherokee or a trusty Ford F-150, having the right setup is essential. 

Otherwise, not knowing the ropes could lead to unsafe towing, potential damage, or even road mishaps. 

So, before you connect that trailer, pause for a second. Know what your vehicle can handle, think about its model and year, and pick the gear that’ll keep your trip safe and hassle-free.
