The OE receiver hitch is notoriously overwhelmed with any load (or not).
Very weak design.
Two design choices for a replacement;
1 that uses the two bolts up into the bumper (like your OE hitch)
1 that doesn't, sits 2" higher and tucks back up under the bumper instead of protruding out.
And of those two designs, they will either be for a 2" or 2.5".
Either CURT or DT, the one you selected doesn't have the bumper bolts and is higher.
Higher can affect your ball mount height. As in, if you were using a 4" drop, you'll need a new ball mount for a 6" drop, to equal the trailer tongue height as before.
