Trailer Couplers

round tongue couplerstraight tongue couplerA-frame coupler

A coupler is a mechanism that is bolted or welded onto the end of a trailer tongue. It fits securely over - and pivots on - the tow vehicle hitch ball. When choosing the correct replacement coupler for your application, consider two factors:


  1. What type of trailer tongue do you have? Straight tongue, A-frame or gooseneck
    • Trailer tongue shape determines the type of coupler your trailer requires.
  2. What is the gross trailer weight (weight of fully loaded trailer)?
    • A coupler's capacity must be equal to or greater than the gross trailer weight. Coupler capacities range from 2,000 lbs to 30,000 lbs, depending on style.

Repairing vs. Replacing Couplers

When a coupler latch has become ineffective at gripping the ball, you might consider simply replacing the latch and ball clamp with a coupler repair kit. Check that the inside of the coupler where the ball sits is free of cracks. If your coupler has a lot of corrosion or damage, it may be necessary to replace the coupler.

Repairing vs. Replacing Brake Actuators

Brake actuators serve two functions: pivot on a hitch ball and operate hydraulic brakes. An economical option to replacing the entire brake actuator is to simply replace the worn parts.

  • Master cylinders
  • Cap and gaskets
  • Push rods
