I decided to make mine a fixed position one. I put high quality silicone caluk on the sides and the top of the interior of the 2.5" truck hitch and then slid my 2" adapter in and put the pin in while it dried. I also wiped all the excess off that came out the back. I could still get it out if I needed to, but all my hitches are 2", so I figured it was a good option for me. Not easy to steal and very easy to put my weight distribution hitch in. May not work for everyone, but will for some.

My cheapo didn't need grinding..

 

I found one laying next to the curb the other day after the snow melted, I drove 3 blocks out of my way, parked on a side street and walked a block to get it, and was just happy as a pig in slop walking back to my truck. Just made my whole day.....

 

Check this out. Cool design. 2.5" shank with intregal locking pin inside the shank. There is a youtube video on how it work too.

Somehow I missed your response. Sorry about that. Here are pics of the two locks they offer that I found. I found them at my local RV store.

I've used pin one for years with no issues at all.

 

This is not that great of a solution.

I have it. It is nothing more then a 2" receiver with a sleeve permanently attached.

It is sometimes a bit tight getting he pins to engage and sometimes I need a mallet to get it out of the hitch.

And since it is a sleeved unit, it loosens up with use. And you then get the slop and noise compounded with three parts interfacing instead of two.

And note, with the DT 2.5" sleeved hitch assembly you do no get the benefit of the increased capacity. The rating is the same as the 2"

 

Does anyone know if this pin is long enough for the 2.5" receivers?

 

I would say no, the bottom lock says it fits class III and IV receivers. 2 1/2" receivers are class V.

 

Thanks that's what I was thinking.

 

This is the one I bought. https://www.boltlock.com/ It fits my 2 1/2" hitch.

Ditto...also, using the reducer (too much slop) caused the pin hole to elongate (using the factory pin). I put a collar on the pin to keep the curved part of the pin away from the pin hole.

 

I have been using a Bolt hitch pin lock for over a year in my three inch receiver and am very happy with it. I had previously used the Reese locking hitch pin with disappointing results. Two of them bent so badly I had to drive them out of the hole and could not reuse them, plus the locks themselves rusted inside and the chrome flaked off the outside.
My WDH has a 2.5" shank, so I only use the single reducer sleeve, but there's still plenty of movement in there. This is particularly hard on hitch pins of any type.
Here is the link to Bolt's website. They sell a variety of locks that are keyed to your ignition key. I really like their products. I will say there have been instances where I had the key in the ignition with the truck running and had to shut it down in order to get into the toolbox or similar. It's great for keeping up with one key for all the locks, but can be inconvenient at times, too.
