Does what is supposed to do. Seems solid and have had no issues. Use it to pull trailers ranging from 3,500lb to 10,000lb. Have not noticed any slop or movement beyond what I had with the stock 2" receiver. The only thing that is not great is that when pushed in all the way to the stop tabs the pin hole is past the pin hole of my receiver so you have to line up three sets of holes rather than just two.




by:

Sliped this adapter right in my Class V Hitch works great. I'm using it with A Curtis adj hitch and locking pins. I'm towing a 24ft 10k cargo trailer with it.




by:

etrailer is always my first choice!




by:

Really love the bump stops that line up the pin holes perfectly.




by:

Item fit as needed with little play. Totally necessary to retro fit my old receivers for lighter applications.




by:

I may be just too picky. I expected a tighter fit but this adapter is perfectly serviceable and will do the job. It might rattle a bit but that is not a big deal.




by:

This sleeve adaptor is perfect. My kids bought me a 2" NFL hitch cover for Christmas, even though my hitch receiver was 2-1/2" I figured I could always use a smaller receiver adaptor for another trailer that I have. Wouldn't have bought it otherwise, but it is a good fit and I may be able to use it for towing in the future (and my "gifted" hitch cover is installed).




by:

Everyone I talk to there is very pleasant and are so willing to help you. Very knowledgeable about their products.A great product fits my truck perfectly. Definitely will do more business with them




by:

Product arrived in a damaged box and had some scratches in various places. Packaging could have probably been more robust.
Other than that, the installation was quick and straightforward. Unless you regularly bench about 100 pounds, you'll need some assistance. Have yet to tow with it, but it should work just fine. Much better than the stock hitch that failed which prompted the replacement. 03 GMC Sierra 3500 CC Long bed, Dually, 6.6L.




by:

the receiver reducer did not fit my truck, the holes for the locking pin did not align. Your site said it fit my truck but it didn’t.


Comments
Sorry to hear that. This is a universal item that converts a 2.5 inch receiver to a 2 inch. Here are the specs to see if it fits: Dimensions: 5.5 inch long x 2.5 inch wide Pin hole diameter: 5 eighths inch

Couldn't be any easier to install.




by:

My recommendation for this product would be to make it longer to distribute the load along the entire length of inside hitch receiver. Also to get rid of the tabs on the front because I had to cut them off to be able to slide my hitch in far enough to line up the pin holes.


Comments
Dont use it. Worthless as far as Im concerned.

by:

Got this so I wouldn’t push the sleeve back furth into the hitch receiver when installing the hitch. It lines up perfectly with the hitch pin holes and the notches keep it where it belongs.




by:

Just what I needed




by:

Perfect fit - quick shipping




by:

works great!




by:

etrailer was awesome as always with getting the product to us in a timely manner




by:

Not much to say. It's a hitch sleeve. Does what you would expect. I do like the little nubs on the end that keep the sleeve from sliding into the hitch too far.


Comments
Same as before. Not much to say. Its been great.

etrailer.com has become my favorite shopping website when I need something for my truck or travel trailer. I now check etrailer BEFORE amazon. They always have what I'm looking for at a great price and the delivery times are really not too bad. I'm spoiled by 2 day shipping but I've come to appreciate the quality of the products here. Having an RV specific website makes finding just the right part a lot easier. Oh and the adapter for the hitch receiver on my 2020 Ford F-250 fits perfectly. I was afraid the spare tire was so close to the back of the receiver that the shank might be too long, but nope, it's perfect.




by:

Product itself looks great. The powder coat finish is a bonus. Biggest issue i have is that the product description specificlly says "made in USA" wich is why i purchased this item. But when i recieved item, the sticker says "made in china". I purchased what i thought was an American made product and recieved a China product.


Comments
Thanks for the review Fredy L. We have noted this and have updated our description on the product page and are in the process of updating our videos as well.

Worked as advertised!! Thank You




by:

Not a precise fit. The adapter does allow some additional movement between hitch and the receiver. I recommend using the same size hitch and receiver whenever possible and skipping the adapter.




by:

this was just the ticket for my new truck. My hitch didn't match the receiver any more so this was perfect. Though the pin that I ordered to go along with it was only just big enough to secure the hitch. I would recommend a longer pin for the 2 1/2" receiver, as it is, I will likely just leave my hitch attached.




by:

Product arrived just as described and works great with my Silverado 2500HD since my hitches and bike rack are all for a 2" receiver.




by:

So far so good. Got this due to our new f250 having the big hitch. Feels solid & time will tell when we hauls a 26ft trailer with it.


Comments
Working great. However due to trailer & a new f250 we had to get a whole new assembly. Oh well for the short amount of time we used it, it worked great. Price was great too.
