Best Trailer Coupler Parts Buying Guide
Before choosing the best trailer coupler you should consider following options:
1. Clevis pin: The clevis pin is the metal piece that holds the trailer to the hitch, and the two are almost inseparable. The clevis pin has a hole for the trailer tongue to go through, and a hole for the shank of the coupler to go through.
The pin has a “clevis” or U-shaped bend to it that connects the shank to the trailer. The clevis is what holds the two together and keeps them from separating.
The clevis pin can be made of steel, aluminum or even stainless steel. The higher the quality of the metal, the longer it will last.
2. Shank: The shank is the piece that goes into the coupler and attaches to the truck. It is the part that the hitch fits into, and the truck pulls against.
The shank can be made of steel, aluminum or stainless steel. The higher the quality, the longer it will last. The shank has a hole in the center for the pin to go through.
The shank rests in the trailer ball, which is the point that the trailer is attached to. The shank has a roller or a bearing on it for the trailer tire to go over.
The shank is the main part of the coupler and is the heaviest piece. It is the part that takes the most abuse, so it should be made of the strongest metal available.
3. Bearing/roller: The bearing or roller sits on the shank, and the trailer tire runs over it. They reduce friction and make the trip smoother for the trailer.
Rollers are preferred over bearings because they don’t have as much friction on the shank. There are two styles of rollers, needle and tubular.
The needle roller has a needle shape to it and is a little more expensive to purchase. The tubular roller is the most common style and is usually the least expensive.
4. Ball: The ball is the point that the trailer is attached to, and it is that part that the hitch fits into. It is the heaviest part of the coupler and takes the most abuse.
The ball is usually made of steel and can come in many different sizes and configurations. They vary in size based on the type of truck and trailer.
The ball can be either a fixed or drop ball. A fixed ball is one that is permanently attached to the trailer and is the same height as the trailer.
A drop ball is one that attaches to the trailer tongue, and the coupler raises and lowers the ball. This is the most popular configuration because it allows for the truck and trailer to be level when connected to the truck.
The hitch is what the truck pulls against, and it fits into the ball. The higher quality hitch you have, the smoother the ride will be for the trailer.
5. Tongue: The tongue is the part that goes into the hitch of the truck, and it is the part that keeps the trailer from tipping over sideways.
The tongue is the lowest part of the trailer, and it can be made of a variety of materials. It can be made of wood, steel, aluminum or plastic.
The tongue is what keeps the trailer from tipping over, and it can be very important to have a proper tongue on your trailer.
The tongue can be a one-piece or two-piece design. A one-piece tongue goes into the hitch and is the same height as the rest of
