    Right now I have 32" BFG's, i'll probably get 33x12.5 with a 2.5" lift. I think i'm running 3.08's now, it's stock. So should I move to 3.73 or 4.11's? It's my daily driver, oh and will I notice a big increase in acceleration?

    Go with the 4.11's, and yes, acceleration will be alot different than the 3.08's.

    Will 4.11's be good on the freeway (65-85mph) I'm thinking the rpm's will be a little higher(obvious) so it would use a little more gas there, but I wouldn't have to step on the gas as much to get it up to speed so it will balance out. What's an estimate $$ to have 4.11's installed?

    not sure about install but i'd definetly go with 4.11s. cuz 33s will only last so long, after them you will want 35 and 3.73s with 35 would suck ( i know i run 3.73s with 36 right now)

    I would say 4.10s so then later when you go bigger tires again it would be already suited for them. Trust me, you will always go bigger /forums/images/icons/smile.gif
    Isntall isn't the hardest thing but is very very time consuming since you will put together then tear apart many times before getting set correctly.

    I have 3.73's and 33's. I like it,but I have a 700r4 also. With your set-up I would get 4.11's. /forums/images/icons/grin.gif

    3.73 if you have a manual or three speed auto. 4.11 if you have Overdrive.

    Go with 4.11's. It'll be well worth it.

    There is not much differnce between the two. I had 3.73's before, but when I got my 14BFF it had 4.10's, so I regeared the front. There is not much (seat of your pants) differnce between them that I can feel. But you will be able to tell a big improvement over the 3.08's /forums/images/icons/cool.gif .
