There is a lot more to utility trailers than just their weight and how much they can haul. Utility trailers come with many different useful parts that are highly useful for owners and future owners to know about. It can be a tedious process researching these trailer parts on your own, so for your convenience below is a consolidated list of the top utility trailer parts to know:
Trailer frame: The main structural component of a utility trailer that supports the wheels, axles, and other parts. It is the foundation upon which all other components of the trailer are mounted. Trailer frames are typically made of steel, aluminum or wood. It is commonly agreed upon that aluminum is the most durable and lightweight material for trailer frames. Primo Trailers are made of aluminum and considered some of the best utility trailers on the market today.
Axles: Axles support the wheels and allow the trailer to be moved. Usually they are made of steel and are designed to transfer the weight of the load from the frame of the trailer to the wheels. Axles can be either single or double (tandem) depending on the weight of the load. It is important to know that the axles on a trailer must be rated for the weight of the load being transported so as not to overload the trailer.
Wheels and tires: Wheels and tires are components that provide the contact between the trailer and the road. Usually they are made of steel and are rated for the weight of the load being transported.
Suspension: The suspension system is a set of components that helps to absorb bumps and shocks on the road while the trailer is in motion. It helps to improve the ride comfort and it can be either leaf spring, torsion, independent or air-ride type. The choice of suspension system depends on the weight and type of the load being transported. Even further, the choice can be affected by the terrain the trailer is traveling on.
Hitch and Coupler: The hitch and coupler are the components that connect the trailer to the tow vehicle. The hitch is what allows the trailer to be pulled and the coupler is the part that holds the trailer in place while being towed. Both components are typically made of steel and must be rated for the weight of the load being transported. The most common types of hitches are ball hitches, fifth-wheel hitches, and gooseneck hitches. Couplers are commonly a-frame, straight-tongue, or pintle hitch.
Lighting and Electrical: The lighting and electrical system includes the lights and wiring that are used to power the trailer’s turn signals and any accessories that may be on the trailer. The lighting and electrical system is an important safety feature that is highly recommended you learn more about. The lighting and electrical system of a trailer includes: tail lights, clearance lights, marker lights, wiring, connectors, and breakaway switch.
Brake system: The brake system is used to slow down or stop the trailer. It can be electric or surge brakes. Some systems are designed to work in conjunction with the brakes on the towing vehicle. Regardless, it needs to be compatible with the tow vehicle’s brake system.
Jack: The jack is a mechanical device that is used to support and level a trailer when it is not connected to the towing vehicle. Usually, the jack is attached to the trailer’s tongue and extends vertically to the ground.
Tongue: The tongue is the part of the trailer that extends forward from the coupler and attaches to the hitch on the tow vehicle. The tongue is designed to transfer the weight of the trailer and the weight of the cargo to the hitch on the towing vehicle.
Ramp: The ramp is used to load and unload heavy items from the trailer. They can be folding or telescoping allowing for easy storage when they are not in use. Ramps come in a variety of types and sizes.

Trailers need electrical power to operate their lights and sometimes other systems like electric trailer brakes. This power is supplied by the tow vehicle through a wiring harness.
A trailer wiring harness usually has a standardized plug that connects to a socket at the rear of the vehicle. This plug can have four wires, five, six or even seven, depending on the trailer type and number of electrical systems. There are also different configurations, such as 4-way flat versus 4-way round.
The wiring harness typically courses its way through the trailer frame where the various wires branch off to the taillight lamps, running lights, brakes as well as other electrical systems and trailer lighting.
Even though trailer wiring has become quite standardized, it can be confusing when you start to discover how many different varieties there are. 4-pin flat, 6-wire square, 7-way RV blade – what does it all mean?
First, the number in each configuration corresponds to the number of wires that make up the connection: 4-way has four wires, 5-way has five wires, and so on. These wires are color-coded and are used for specific functions, based on the color: green is for the right turn signal / brake light. Brown is for the taillights. White is the ground connection, etc.
Secondly, terms like way, pin, wire and prong are all synonyms. Simply put, they all mean the same thing. You can call it a 4-way, or you can call it a 4-wire, or you can call it a 4-pin – it’s the same configuration.
One caveat is that blade is more of a reference to the style of the individual contacts. Instead of a pin, each contact point is a flat blade-like piece of metal. On RV blade harnesses, the blades are arranged in a circle, which brings us to the final point.
Lastly, the terms flat, round and square are indicative of how the wires are arranged. In a flat configuration, the wire contacts are all laid out in a single, flat line. In round, the wires are in a circle. You get the idea.
When considering wire harness types and perhaps which one to buy as a replacement, the best course of action is to look at what you already have on your trailer. If it’s a 4-way flat, replace it with another 4-way flat. If it’s a 7-way RV blade, replace it with a 7-way RV blade.
