Review: Great quality! - Excellent quality!!
Review: Yeah... this will work if you need a 2 5/16" ball! - I had a super hitch.... load leveler bars, for my travel trailer. Someone STOLE it from my front yard! So... I had simple hitch with lowering ball (my stupid F-150 truck is TOO HIGH!) and bought this ball. Well... it DOES connect to my expensive travel trailer. I put it on a simple hitch thing with lowering ball height. Yeah... it works. Nothing wrong with this ball if this is what you need! It SUPER GREAT for what it does!

## Questions & Answers

**Q: What is the height on the ball end?**
A: The ball is a regular 2 inch ball. Height depends on the receiver hitch

**Q: ball marks on top says 2 am i missing something**
A: It’s a 2 5/16” ball not a 2”

**Q: Is this a metric thread?**
A: It is not a metric thread.

**Q: Whats the socket size for nut?**
A: The nut on a hitch ball with a 1-1/4 inch shank takes a wrench with a 1-7/8 inch socket. A hitch ball with a 1 inch shank will take a wrench with a 1-1/2 inch socket.
So the best tool for this ball is a 1 1/2” box end wrench.

### ⭐⭐⭐⭐⭐ Great hitch ball value and performance
*by H***N on January 31, 2022*

I ordered this hitch ball as I will be renting a trailer that has 2 5/16" coupler. I normally pull with a 2" connection and use a Curt 2" dia., 1" shaft, 12,000 lb. ball normally. I ordered this from Amazon Warehouse and was concerned about reviewers that said the threads were messed up or labelled incorrectly. I am happy to report that product I recieved (P-1B1) is showroom perfect and was shipped in a box as opposed to a mailer envelope. For this size and rated ball I couldn't be more happy and with this price it is a fantastic deal as compared to any other items I looked at online. Good job Amazon...
