I have 4:88 in mine and turning 33" swampers I dont have much of a 4th/5th gear going up hills at all! 3rd gear is my power gear. This might apply to your truck as well if you do 34" with the 4:88. My Boyfriend has 36" swampers with the stock gears (4:10) and he doesnt even have 5th gear..he's truck cant pull it!..
