????? Posted pics of installation? On a 2012 SRT8??????
Aftermarket hitches on the WK2 protrude under the bumper and mount to the OUTSIDE of the frame rail. The factory unit provides dual axis mounting spreading the load more evenly through the unibody by attaching INSIDE the frame rail and bolting to the side and bottom of the frame. Besides, the current aftermarket hitches most likely won't even fit under the SRT bumper cover and certainly won't take advantage of the built in hitch over that comes with the factory package.
Bottom line, if you want to tow order the tow package OR install the factory tow package, including any additional factory wiring after the fact. I can not think of any legitimate reason to not use the factory parts. I don't think Jeep has anything to worry about with the aftermarket.
I don't really think the OP meant installing a new hitch, he said upgrading THE hitch, which implies a hitch exists in the first place. There's only 1 type of hitch available for the WK2 and it's a Class IV. I think the OP has confused the 5K tow limit with the Class III hitches companies put on crossovers and minivans.
