XD Hitch Terms

XD Platforms     XD Ball Mounts
XD Platforms XD Platforms are the backbones of the XD Hitch. Everything attaches to it, so you should only have to install it once. XD Ball Mounts attach to the XD Platforms and allow you to hook up to a variety of trailers sizes. Including units with 2 hitch balls for easy changeover. And don't forget the innovative Swivel-Loc Mount which allows you to hook in one shot. XD Ballmounts

Selecting a Hitch

Verify Load Capacity
As a general rule bigger is better in the towing world. If you are going to error with the load capacity (defined by Classes) it is much better to go bigger than smaller. There are several ways to figure out how much capacity you need in your towing application. Because the shear number of vehicles, it is hard to suggest for specific vehicles.

Educate yourself on the items below before making a decision:
  • Dig out your vehicles owner's manual to find the maximum towing and tongue weight limitations
  • Check the hitch receiver bolted to your vehicle, it should have a load capacity on it
  • What is the maximum weight you intend to tow? (this should include trailer fully loaded with gear)

Always choose a hitch that is strong enough to handle the maximum anticipated total weight of the trailer but does not exceed the towing capacity of your vehicle. Buying a bigger hitch does not necessarily mean you can tow larger trailers. Never exceed the limitations of your vehicle!

Choose the Size of Drop/Rise
There is a lot of talk out there about the "perfect" ball height for a trailer. The reality is that it is specific to truck/trailer/load and many times you just need to adjust on the fly. The ultimate goal is to simply keep your trailer as level as possible when fully loaded. Below is a guide that will help you decide the range of adjustment that will suite you best.

Level Towing Hitch Level
Up 5" to 8-1/2"      
1-1/2" to 5"      
0" to 1-1/2"      
Direction Receiver Height - Tongue Height XD 3" Adjustable Platform XD 6" Adjustable Platform XD 10" Adjustable Platform
Down 0" to 3"      
3" to 6"      
6" to 10"      

Hitch Classes

Trailer hitches (consisting of receivers and ball mounts) are typically given a "class" rating to define their weight capacity. Classes range from class I to class V. All hitches will have a specified towing capacity and hitches within the same class will have the same weight capacities.

  Class I
Trailer GVWR*
2,000 lbs (910 kg)

Max Tongue Weight
200 lbs (91 kg)

Class II
Trailer GVWR*
3,500 lbs (1590 kg)

Max Tongue Weight
350 lbs (159 kg)

Class III
Trailer GVWR*
5,000 lbs (2270 kg)

Max Tongue Weight
500 lbs (227 kg)

Class IV
Trailer GVWR*
10,000 lbs (4540 kg)

Max Tongue Weight
1,200 lbs (545 kg)

Class V
Trailer GVWR*
12,000 lbs (4540 kg)

Max Tongue Weight
1,200 lbs (545 kg)

* Gross Vehicle Weight Rating (GVWR) refers to the maximum weight capacity of the trailer AND all cargo.

**Weight Carrying (WC) hitches are what most think of when towing, they are designed with a simple ball and socket attachment.

***Weight Distributing (WD) hitches utilize additional stabilizer bars that help distribute the tongue weight of the trailer to the the front axle of the vehicle to help with larger loads.

General Terminology

Ball Mount
Ball mounts are installed into the reciever, they typically have a hitch ball attached. But can also have specialty attachements such as a pintle.

Gross Combined Weight Rating (GCWR)
The maximum permissible combined weight of the tow vehicle and trailer when they are fully loaded for travel.

Gross Vehicle Weight Rating (GVWR)
The maximum permissible weight of the trailer when they are fully loaded for travel.

The combination of a receiver and ball mount make the hitch.

Hitch Ball
The ball-shaped attachment to a hitch onto which a trailer coupler is attached.

Used to fasten any insert (ball mount, bike rack, etc.) into a receiver hitch. Available in standard and locking configurations.

Pintle Hitch
A pintle hook is used with a lunette ring is a type of trailer hitch. A pintle hook and lunette ring makes a more secure coupling, desirable on rough terrain, compared to ball-type trailer hitches.

Portion of the hitch that is attached to the towing vehicle.

Tongue Weight (TW)
The downward force exerted on the hitch ball by the trailer coupler.

Vehicle Tow Rating
Make sure your tow vehicle is capable of towing the intended trailer or accessory. The trailer or accessory and the vehicle work together in determining the maximum capacity. In no case should the Gross Trailer Weight (GTW) or the Tongue Weight (TW) exceed the towing capacity of your vehicle, your trailer or your accessory. Find this information in the vehicle owners manual.

Weight Carrying
Type of trailer hitch most people think of when they consider trailer hitches. It is the basic trailer hitch that provides a simple ball-and-socket arrangement to connect the trailer to the towing vehicle.

Weight Distributing
This type of hitch has an attachment that slides into the receiver to redistribute the weight on the tongue. The hitch usually has two spring bars, one for each side of the trailer, to lift and apply leverage to the tow vehicle. This redistributes weight from the rear axle to the front and improves vehicle stability while towing.
