Excessive receiver/shank play on new truck

[myredracer]

Have a new-to-us '12 GMC 2500HD and tow a TT with Reese DC WDH. I am guessing hitch play has been discussed ad nauseum. The truck has a heavy duty trailering package option with a 2" receiver insert.

There sure seems to be a lot of excess play. I measured the size difference between receiver and shank to be over 1/16". I don't care about vertical movement, but I have to wonder about side-side movement and the effect on the WDH or shank or receiver wear.

Wondering if a shim is available or maybe I could make one up from sheet metal? Or is this amount of play something to just forget about? Have a Blue Ox immobilizer clamp but won't fit on the GM receiver tho. Not sure it would work anyway with that amount of play.

Lose the adapter piece (actually keep it for in a pinch situations) and get a 2-1/2" shank hitch for your new truck. Other wise over time, if you tow any decent weight or with any frequency, the receiver pin holes will wallow out and the hitch pin will bend.
