I have read that you can't change your towing rating, but let me ask this:

If you have an auto with a 3.55 rear end you tow rating is around 9500 or so, go to a 4.10 and that number goes upto 11k or so. Now add a 6 speed and a 4.10 you might see 13k or so. If you have that auto with the 3.55 you change over to a after market tranny (DDT or ATS) and get a 4.10 rear end have you just increase your towing rating?

If you have the 6speed and the 4.10 you will not get any thing more than what the books says but are not most of the 3/4 tons the same (not including the rear end and tranny). Same brakes, tires ect...

Just wanted to know?

KC,
If you post that on one of the RV boards, the "weight police" will have a field day. If I understand correctly, nothing you do yourself will change the "rating" the truck is built with. An aftermarket supplier who is so licensed can make changes which will change the rating numbers.
Theoretically, changing to 4.10s will give you the rated pulling capacity for that ratio. Either aftermarket auto is still an auto in Chrysler's eyes.
Remember that these ratings are not an enforcement number. Here in NY, you get 22,400 pounds per axle or 36,000 on a pair and I can't see one of our Dodges making that weight. However, you can get caught running over your registered weight.

So what you have on the manufacturers tag, is all you get.

 

Forget the weight police (show me one) AND the sticker. It'll pull what it will pull and stop what it will stop. If different trans/axle is rated for more and you install that (the brakes are identical) go for it.

Many folks have a story about the weight police busting someone, but the number of first hand experiences I've run into.....I can count on my toes on my 3rd foot.

I ran my '83 Ford F250 all over western US and Canada wighing in at 11K (sticker says 8.6K).

Commercial...whole nother ballgame.
