Q: What types of trailer couplers are available?

A: We offer two types of trailer couplers, including a bumper pull (coupler clamps onto a hitch ball at rear of vehicle) and a gooseneck coupler (a pipe or square tube with ball coupling, clamps onto hitch ball mounted in the bed of a truck positioned above the rear axle).

Q: What types of bumper pull couplers are available?

A: Straight tongue

A-frame Adjustable tongue

Flat mount

All are available in both stamped and cast coupler designs.

Q: What is the difference between a stamped and cast coupler?

A: A stamped coupler is formed from high alloy sheet steel and the coupling head is integrated into the coupler body. This is a method of producing couplers that are not as durable as a cast coupler, but typically cost less. A cast coupler has a cast or forged coupler head that clamps onto the hitch ball. This provides for increased wear and durability as compared to a stamped coupler design. Cast couplers are typically more expensive than stamped couplers, but typically provide greater durability and longevity.

Q: What is a straight tongue coupler?

A: A straight tongue coupler is typically used on smaller trailers that have a straight tube or channel extending from the front of the trailer. These couplers are typically bolted on, although weld-on versions are also available. The standard ball size for straight line couplers is usually 1 7/8” and 2”. However, there are some 2 5/16” models available. Weight capacity for straight tongue couplers typically range from 3,500 – 12,500 lbs.

Q: What is an A-frame coupler?

A: An A-frame coupler is used on trailers with a triangle or “A” frame trailer tongue. These couplers are typically welded to the trailer frame. A-frame couples are designed for multiple types of trailers using either a 2” or 2 5/16” ball size. Weight capacity for A-frame couplers typically range from 5,000 – 15,000 lbs.

Q: What is an adjustable tongue coupler?

A: An adjustable tongue coupler is used with a channel that welds to the trailer tongue. It can be raised or lowered on the channel mount depending on what height you may need to ensure level towing of your trailer. Adjustable tongue couplers are available in 2” and 2 5/16” ball sizes, and typical weight capacity ranges from 7,000 – 20,000 lbs.

Q: What is a flat mount coupler?

A: A flat mount coupler typically mounts to a flat metal plate that is welded to the frame of the trailer. Flat mount couplers are most often used as an alternative to tow rings, more often in reference to pintle/drawbar eyes used on heavy trailers. The typical weight range for a flat mount coupler is from 14,000 – 25,000 lbs.

Q: What capacity coupler should I buy for my trailer?

A: You will need to find the gross trailer weight rating (GTWR) of your trailer. If the GTWR is not marked on the trailer, you should contact the trailer manufacturer. The capacity rating of the coupler must exceed the GTWR of the trailer.

Q: What is a fold-away hinge kit?

A: These hinge kits are designed to be used with straight tongue couplers on boat trailers. They fit on a trailer tongue or tubing that is either 3”x3” or 3”x4”. They bolt on to the tube and can be folded away by pulling the clip then removing the pin. They provide the advantage of saving space by folding the tongue away for storage in a convenient place of your choice.

Q: I recently had a small collision that damaged my coupler. Can I repair my coupler or should I replace it?

A: Various replacement parts are available for many couplers. Your choice of repair or replacement will depend on which coupler you have and what specific part was damaged. Another consideration may relate to whether your coupler was a bolt-on or weld-on style coupler. My straight tongue coupler is loose when it’s latched to my hitch ball. I already tightened the lock nut underneath the clamp mechanism, but that didn’t fix it. What should I do? If you already tightened the lock nut and that didn’t resolve the loose fit, then the coupler’s internal parts are likely worn and need replacement. There are latch repair kits available for most couplers.

Q: How do I maintain my coupler?

A: The most important part of maintenance is to keep the ball pocket and mechanism clean. In addition, the following procedures should be performed at least annually: Check welds and mounting bolt torque. Grease the ball pocket. Oil the pivot points with SAE 30 motor oil. Inspect any retaining pins and replace if damaged or missing.
