Hummer H1 Braked Vs. Unbraked Towing Capacity
All vehicles have different towing capacities based on whether or not you’re towing a trailer that has trailer brakes installed.
Trailer brakes allow the trailer to stop faster than if only the vehicle is using its brakes, allowing the vehicle to tow more weight, so braked towing capacity will always be higher than unbraked towing capacity.
Hummer H1 Towing Capacity Factors
There main item that determines how much weight a Hummer H1 can pull is the body style or trim.
The H1 body style / trim configuration impacts the towing capability based on additional weight added.
For example, many times the open top body style of the H1 can tow more than the enclosed version.

Hummer H1 Tow Packages
Does The Hummer H1 Have A Tow Package?
The H1 doesn’t automatically come with a tow hitch installed, so you’ll need to install one yourself.
Hummer H1 Towing: What Do I Need?
If you plan on towing anything with your H1, you’ll need a tow hitch and wiring harness.
Depending on what you’re towing, you’re going to need a ball mount (aka a trailer ball hitch) so you can attach items for towing.
Make sure to get the right trailer ball size that matches your hitch and trailer.
Hummer H1 Tow Hitch
Trailer hitches come in different hitch classes, which are rated for different vehicle sizes and weight limits.
The Hummer H1 has a Class 4 hitch.
Here’s a great ball mount option so you can hook up different types of trailers for towing with your H1:
- DEPENDABLE STRENGTH. Rated to tow 3,500 pounds gross trailer weight and 350 pounds tongue weight, this ball hitch offers dependability for your towing setup (weight capacity may change if trailer ball is removed)
- VERSATILE USE. This trailer hitch ball mount comes with a 1-1/4-inch shank to fit virtually any industry-standard 1-1/4-inch receiver. The ball mount has a 3-1/4-inch drop, 2-inch diameter ball, 1/2-inch hitch pin hole and 7-1/4-inch overall length
- READY TO TOW. Hitching up your trailer is easy with this ready-to-use trailer hitch ball mount. It comes with a pre-attached tow ball for ready coupling and a trailer hitch pin to securely mount onto your hitch receiver
- CORROSION-RESISTANT. For long-lasting use, this ball hitch is protected with a durable black powder coat finish, and the trailer ball has a polished chrome plating. These finishes resist damage from rain, dirt, road salt and other corrosive threats
- EASY TO INSTALL. To install the trailer hitch ball mount on your vehicle, simply insert the shank into your vehicle's 1-1/4-inch hitch receiver. The rounded shank makes installation easy
Hummer H1 Tow Hitch Installation
If you’re considering having a tow hitch added to your H1, expect to pay between $100 and $200 to have a tow package professionally installed (excluding the cost of the tow hitch and wiring harness).
If you’re handy and looking to save money, you can install the trailer hitch and wiring harness yourself.
Always follow the manufacturer’s directions and use proper safety precautions.
Hitch Receiver Vs Rear Step Bumper Towing
Some vehicles allow for bumper towing, which means you can mount a tow hitch ball directly on the bumper instead of installing a tow hitch to the vehicle’s frame.
Can I Bumper Tow With Hummer H1?
You can bumper tow with the Hummer H1, but we recommend using a tow hitch instead, as your towing capacity will be reduced when bumper towing.
How Do I Know If My Hummer H1 Has A Tow Package?
You can start by looking under the rear bumper of your H1 to see if you see a trailer hitch or trailer ball.
That will give you a good indication of if you have a tow hitch already installed on your H1.
Another way to research this is by checking the paperwork that came with your vehicle or taking it to a local dealer to see what’s installed.
Make sure to have your VIN (Vehicle Identification Number) handy if you call the dealer so they can look up the exact specs and whether or not your vehicle has any towing packages or features installed on it.
