    I was running a rear 10 bolt on 35's for awhile. Then I blew the Gov-Loc up. Now im running a 6-Lug 14 bolt Semi-Floater.

    Everyone I know with 10 bolts run 36 TSLs and they havent broke the 10 bolts yet. Just the u-joints but I have done that with my 31 ATs. So I would say go for the 35s

    I used to have 10b + 35x12.5x15s. Worked well, my 10 bolts were built tho. full floating kit, chrome moly shafts, the whole nine yards. IMO, the 10bolt front axle is workable with pretty big tires (i dunno, maybe 37s?) but the 10b rear is pretty much junk, mainly because its semi-floating.

    If ur rich, just go d60/ff14b. If ur poor, a beefed 10b front and a semi floating 14b rear would be a good option. You'd get to keep ur 6 lug wheels, and the sf14b, while still semi floating... is quite a bit stronger than the lowly 10b rear.

    I think the weakest part of a stock 10 bolt rear end is the stock carrier. Out of all the rear diff's ive seen broken its almost always been carrier related. Thats why I say if your never going to go bigger than 35's throw an aftermarket carrier in the back and carry some spare shafts and go play away.

    i have been running 35'son my 10 bolts for about a year without a problem , except for the driveshaft joint , but
    thats an angle issue.
    i am looking a 14bff, so i can have better wheeling
    security.

    Like mentioned above one of the main weaknesses is the spider gears and or govlock differential. I personally broke my govlock on the street with 32's and a stockish 350.

    I had it replaced with an Auburn full case posi after that and never had a problems with the 32's and the 10 bolt again. I never was really "hardcore" on it though. Mild to moderate wheeling. If you had a good set of gears and a full case locker or posi then a 10 bolt isn't really that bad. You better carry spare parts because you might need them, but it can survive with a good driving technique.

    Ya, I am still running the 10 bolt front. I did upgrade the rear to 14bff. The front is now locked and on 35's so now I need to get some wheeling in on it and see how it holds up. But some of the AZ guys run 1/2 front and rear with 35's and beat the ever loving piss out of them. They do brake parts, but not as often as most would think they would.

    I used to run open 10 bolts in the front of mine all the time, in fact only one of my 4wheeling crowd that did. I ran 35's for 3 years with no problems then went up to a 38.5 tsl then back down to a 36 which it stayed that way for 2 years. I say 35's and a 10 bolt will be fine, just make sure your front and rear gears match (thats a big duh but seen people overlook it lots).

    but it's exist the risk of overheating the 700R4 with 35's and stock gears?

    If your stock gears are 3.08 it is for sure a bad combination. For 35's you need minimum 4.10 gears to keep the engine and tranny in the RPM range where it's supposed to be working.

    DEFINITELY! If your 700r4 tranny is an 85 model, they already are prone to failure. If you try running 35's and stock gearing with that tranny, you might as well start saving your pennies for a new one now. /forums/images/graemlins/1zhelp.gif

    Just don't run in OD if you have crap gearing and a 700R4. Run in D all the time unless you are doing 75+ on a flat stretch of highway.
