I'm pretty sure its two different parts. I never got to actually do the repair because mine went out under warranty and dodge did the fix. I've heard of others that had this problem and they just get the parts from the dealer. I don't know if there is an aftermarket replacement part, but you could install an aftermarket valve body built for towing. I'm sure someone else will chime in with more info. I have had this repair done now for 3 or 4 yrs and I've put about 80k miles on it since then. I also haul heavy on occasion, sometime dads antique tractors and equipment for others.
