the 08 4.6's have the 8.8 right?

if so do yall think 4.10's will be fine for 33's. right now i have 3.55's and i drive mostly in the city, and it draws out each gear so much. The banks exhaust is starting to ignoing. lol

 

4.10s or 4.11s will be fine..if ur runnin 35s i wouldnt go to 4.56. a lot of guys do for towing and to be able to move their truck with those big tires..but gas mileage will be terrible...ive got big beef 305/55/20 and ive got 4.11. truck really gets up and goes and its only runnin at 2000 rpms at 70 mph
