It all depends on how much road driving this truck sees. If you still do a fair amounmt then you should consider 4.27's. If you are in between then 4.56's and if you primarily run offroad then 4.88's or better. The 3.07's with 35's will make it a chalange to even get your truck into 4th gear. Forget 5th unless you get up to about 90. Your 0-60 should take approx. 3 days. I don't suggest running those tires until you get some gears. Yes you can get gears for about $129 but always remember to get the master install kit with those. You should change out your seals and your bearing while your in there and these should come with a good masterr install kit. These kits run between $100 and $150 per axle. The other thing is to consider that you will need a new carrier to put in these gears, they are about $100 each also. So the budget of $400 - $500 per axle is about right. Good luck, Let me know if you have any questions
