im still running the stock 3.55's with my 35's and a 3 inch level and 4.6, needless to say its a pig. these tires are wearing down and im going with 33's next. i want to bring the final ratio back to around what it was with 31's and the stock gearing. 3.73's or 4.10's with 33's? thanks

 

Most guys here run 4.10 or 4.56 with the 35" on the 5.4L. With your size motor I would go 4.10
