Re: Towing with SRT springs
I believe the tow rating for the SRT's is based on the hitch, rather than the springs. I have SRT suspension (sways and lowering springs) under my 06 GCO and I can tell you that the ride is firmer and much more stable than with the stock suspension. I also have the SRT bumpers and I had the stock hitch refitted to fit with the deeper SRT rear bumper. I've towed well over 2500 lbs. with it and it's like it isn't even there. I say go for it, but I would also recommend the sways to go along with it.
