If you remember the older GM hitches that came on GM HD trucks up to 2007, they were very poor hitches. When I decided to tow with my 05 I immediately changed the OEM hitch out to a Torklift hitch.
Good move. The OEM receiver on my '06 developed breaks in some of the welds, and was replaced with an aftermarket model by the dealer.
My '03 didn't appear to have any cracks but after reading on here about the weak GM hitches, I replaced it with a Curt class 5. The Curt bolted right up after I cleaned and touched up the frame with some black Rustoleum. I suspect there is a lot less flexing going on as my tongue weight can be between 1100 and 1200#'s.
I also relocated the trailer plug receptacle with a neat
Pollak 7pin/4pin into the bumper next to the lic plate like I've seen on newer trucks. Now I can plug in my cargo trailer without using an adapter or my Chevy logo hitch cover tail-lite. If any one is interested in doing this mod, I used a 1.5" knockout to punch 2 holes through the steel bumper. Only a little filing was needed to clean up the edges where the 2 circles met to create the oval opening. The knockout created an extremely clean opening and looks professional.
