How to Torque Hitch Ball When Installing into Ball Mount  


I am looking at the 40008 Ball 2 5/16 and also the 45340 ball mount. Is there a combo package with a mounted ball? This is for a 2inch receiver tube. What is the easiest way to get the 450 ftlbs torque spec?

We don't have a combo of the Curt Hitch Ball # C40008 and Curt Ball Mount # C45340. The ball mount is extremely heavy-duty, rated up to 17,000 pounds.

I think it's safe to assume you don't have a torque wrench rated up to 450 foot pounds just laying around. In which case you'll never really measure it at 450. When tightening the ball you want to make sure you get the lock washer so that it's completely flat.

One way to help you do this is to put the ball mount in your hitch receiver sideways so the hole is vertical. Then install the ball that way. So you can use something to hold the ball with one hand and torque the nut with the other. Another way is to hold the ball in a vice, if you have one. You can wrap a thick rag around the ball so whatever you're holding it with doesn't damage it.
