When you want to tow a trailer or RV behind your vehicle, grabbing the right ball hitch is essential. Your vehicle won’t tow at its best efficiency without the right parts. Understanding the dynamics of the right size ball hitch is vital.
If you’re gearing up for a summer adventure, start by doing a little research. Keep your travel party safe by arming yourself with knowledge. These tips will help you choose the right ball hitch size for your next excursion. Let’s get started!
What Is a Ball Hitch?
A ball hitch is the little silver ball you see on the back of a truck or SUV. It’s part of the system you use to attach a trailer or RV to the back of your vehicle. A receiver hitch accessory gives your trailer something to hold onto when connecting it to the hitch.
What is Ball Hitch Shank?
The hitch on your truck or SUV will have an open square or the receiver tube. The ball hitch shank is the piece of your ball hitch that slides into the receiver tube. To choose the right ball hitch shank, measure the opening on your receiver tube. The side of your receiver tube and shank relate to the weight you can safely tow. Smaller shanks can carry less weight, and the bigger shanks can carry heavier loads.
How Do I Know What Size Ball Hitch I Need?
The trailer or RV you intend to pull should have a coupler on the end. You choose the right ball hitch size by measuring the inside of the coupler. If you’re also purchasing the coupler, ensure the ball hitch and coupler sizes complement one another.
However, some couplers are adjustable. If you have a ball hitch that’s a little bigger or smaller than the coupler, see if you can adjust it before investing in a new one.
You must also consider your vehicle’s towing capacity and the trailer ball hole diameter on the shank. The ball must thread snugly into the connecting pieces to maintain the system’s integrity.
How to Measure Hitch Ball Size
There are four main factors to consider when measuring a hitch ball size. The ball diameter, the shank length, the shank diameter, and the rise are all essential to choosing the proper ball hitch for your setup.
The ball diameter is the diameter of the hitch ball. The shank length is the length of the threaded part of the ball hitch’s stem. The shank diameter is the diameter of that area, and the rise is how high the trailer ball sits off its base.
Know What Size Shank You Need Too
The hitch shank may not completely line up with the coupler on the trailer you’re hoping to pull. If the trailer coupler is lower than the receiver on your hitch, you need a drop in the shank to create a level tow.
First, ensure the shank will fit into the receiver by measuring the inside distance of the opening. Then measure from the top of the receiver opening to the ground. Measure the distance from the bottom of the coupler to the floor. Then subtract your receiver height from the coupler height. This number will tell you whether you need a drop in your shank.
