by:

Appears to be a well made, heavy duty adjustable ball mount. Excellent packaging, arrived undamaged. A little leary of the pin retainer clip, but will see how well it stays in place after some use.



by:

Very high quality product. Good fit and finish. The only reason it didn't receive 5 stars is the product does not provide a means to lock the ball attachment, and thus the risk of the ball attachment or the trailer attached to the mount is substantially higher. Therefore, at this cost, it should come with at least one of the pins that hold the ball mount component include a lockable pin to prevent theft (either the ball mount itself or the attached trailer).

If you are needing a lockable hitch pin, I highly recommend part # e98881. This hitch lock, will fit your 2.5 inch receiver, and if you are needing more than one lock pin, you can always get this one keyed alike.



by:

Far exceeded what I expected. This is a real, heavy duty hitch.



by:

The Curt adjustable hitch design has a simple, clean look to it and is easy to adjust. The included rubber damper to reduce clatter was an unexpected bonus.



by:

Super heavy forged piece. The beam is seriously stout, no formed or welded joints here.



by:

Excellent service. Delivered on time!



by:

I am impressed with the product. I hope more attachment options are made for this set up. Works great pulling 16,000 pound 34 foot cargo trailer.



by:

Very nice. Very heavy duty. Perfect height for my 2023 GMC 3500hd.



by:

Haven't used it yet, but it appears to be well made. Over all fit and finish is top notch.
