Stinger Hitch Extensions: How Far Can You Extend a Trailer Hitch?

Stinger Hitch Extensions

Stinger hitch extensions can be extremely useful when attaching your trailer to your vehicle, moving the heavy load further away. They give your hitch additional leverage, but how far can you extend a trailer hitch?

Different trailer hitch extenders vary in length and dimensions, but you can generally extend a hitch up to 8 to 18 inches. Quality stinger hitch extensions, like CURT and REESE extenders, provide some of the longest extension lengths. 

Keep reading to learn how far you can extend a trailer hitch. We’ll also share our list of suggestions for seven hitch extenders. We’ll detail their maximum extension lengths, safety factors, specs, and pros and cons. 

How Far Do Trailer Hitches Extend?

Trailer hitches can extend to varying lengths, and typically, you’ll want to extend your trailer hitch according to your desired tongue weight. The stinger (also known as the ball mount) is the portion of a trailer hitch that carries the ball and fits into the receiver. When installed, your hitch extension will be between the stinger (ball mount) and the trailer getting towed. 

Some trailer hitches extend as little as eight inches, whereas others extend up to 14 inches, 16 inches, or 18 inches. 

A few key differences exist in how far stinger hitch extensions can stretch your hitch (and how that affects tongue weight). Explore these differences in the example extenders in this table:

CURT 45796 Trailer Hitch Extension18 inches350 lbs

How Stinger Hitch Extensions Affect Load Capacity

When using a hitch extender, one thing to keep in mind is that it will significantly reduce the load you can tow. It reduces the max “tongue weight” (the static force the trailer tongue exerts on the hitch ball). 

Not exceeding your tow vehicle’s hitch or tongue weight is critical to safely towing a trailer, navigating turns, braking, etc. Too high tongue weight can destabilize your moving vehicle by overloading its rear tires. 

You need to reduce your tow load when using an extender. With most hitch extenders, you need to know that the extension process can reduce your tongue weight by up to 50%.

Below, we’re giving a brief guide to seven of the best hitch extenders on the market. These extensions come in varying lengths, with slightly different tongue weight capacities to be aware of. Follow along as we explore their comparative features, benefits, and costs.
