Hey Mr. TBSS- having done some camwork on these trucks. What's the lift/ duration profile of the stock cam? Thanks. Back to the subject at hand, 4.10's are the best move at this point or beter as mentioned.............

i would go with the new 4.30's. i did the 3.73 to 4.10 swap w/ 33's and there was a noticeable difference but for towing i would get atleast 4.30's. save your money and just get a radix and dont even fool with any of the other stuff. Do you just prefer a gas burner? Might consider trading to a diesel truck. That 4l60e isnt gona last long at all towing all the time.

I don't tow alot and it is usually just our RV trailer or a snowmobile trailer. I'm just looking for a little more grunt, and was hoping a cam might help.

I did both... re-geared to 4.56 and Radix. Couldn't be happier with it. Well... if i got better MPG then i'd be much happier.
