    Gear Changes Due To 35\'s

    What stock ratio do you have? If you have 3.42, 3.73, 4.10 then you should be ok. Hell I ran 35's with 3.08's for a long time. /forums/images/graemlins/eek.gif /forums/images/graemlins/thumb.gif

    if they are true 35's , you'll feel it in the gas pedal.NOthing terrible, IMHO. It will be slower off the line, and you'll put a bit more stress on your tranny, so be sure to do the usual cooler upgrades, temp gauge, etc.

    I wouldn't waste a dime on a rear 10 bolt. I'd consider changing a front, but definitely swap to a 14 bolt full floater in the rear before you even think of messing with your gears.

    yeah, swap in a ff14b b4 u swap rear gears.

    afa the ratio, I want 5.13s so I can actually use my 700r4s OD. I run 35s onroad, 39.5s off. my 4.56s just arent low enough.

    I'd go for the 4.56 with the 35s if you don't have the cash for a 14 bolt and you aren't beating the crap out of your rig. I started out with a 3.73 in my sub with 33s and I thought it was a doggggggggg. I couldn't use the OD on the highway until I got up to 85MPH. I am going to 35s on the next tire change.

    Here we come with the 1 ton SHeeple.... They tell you you should swap in a 14FF and dont even ask you how you wheel. I wheel pretty hard trying anything I can possibly think of and my 12 bolt is chugging along nicely.... I have had times on rocks where I have it full throttle with the frotn and rear bouncing up and down without breakage on 35x15.50 TSL's.

    So what type of terrain do you wheel?

    well, i tend to recommend ff14b swaps because the axle is dirt cheap and solves a lot of strength issues other axles have (translation: will cost less down the road too). I never said anything about doing a full 1-ton conversion... just the rear end. If this guy breaks an axle someday and his tire drops off 'cause he still has a SF axle.. he'll wish he had saved money and gone ff.
