    The best way to go is to "full float" that 12 bolt out from under your truck and slam in a 14 bolt SF 6 lugger. It'll be cheaper and if/when you snap an axleshaft, $90 or so will getcha a new one. Not so with a custom FF shaft! Oh yeah, and the SF 14 bolt is already a much stronger shaft at 1 3/8" x 33 splines!!!

    <font color=blue>Axles are a big compromise. The strength comes from the size of the parts more than the material or design. thats why a 14 ff is so strong, it has a 10.5" ring gear, huge housing, huge tubes, huge shafts and huge everything else too. The downside is the weight and massive clearence loss. If your only running 35s, a set off alloy shafts with bigger bearings, a full-case locker and a quality ring & pinion set should be fine as long as your easy on the gas pedal (which I'm not, theres a 14 sitting in my garage for this reason). The green ORD Jimmy runs a 12 with 37x12.5s and its been over Moab and a ton of other places. The Warn kit will make the 12 less likely to break axles, but its expensive and makes the R&P the weak pion. Everytime you upgrade a part of the drivetrain, you make another part the weak link. Its all relative to your driving style and budget.

    is the 14 bolt FF strtong enough to take a hit from a rock directly? and to go to bigger tires i would need to cut out alot of finders to fit them with only 5inches of lift.Wich i have no problem doing.

    Not that I've ever done it on purpose but yeah the 14 bolt will take a 'direct' hit and laugh it off.[​IMG]I've done it at least 3 times. I'm using 35" MT's with the 14 bolt FF, and ground clearance is diminished but I like the bulletproof strength. Besides I can always go bigger in the tire department![​IMG]

    I run the full flooter kit from ORD. Till I went to it I was trashing the 12 bolt ever time I did hard wheeling! I did not want to go to the 14 bolts as I did not want to change to 8 lug tires and the late model 6 bolt ver is hard to find Plus I would have to get the rear drive shaft changed yet one more time. I installed the flooter kit in an afternoon useing saw-all and coman shop tool. I did get the center holes trun the day before.
    After putting in the flooter I find that the blazer drove a bit better amd the rear hub run much cooled almost cold! You have the option of running the rear wheel bearing wet with rear end oil or packed with grese I ran them wet.

    If i had it to do all over and was running a stock 12 bolt I would still beef the 12 and add the flooter kit and disc. And not go to the 14 I like the clearance of the 12 bolt and after the monye is counted up the 12 bolt is still cheaper.

    I understand the jeep thing I drive a BLAZER!!
