    Everyones tire size, pressure and wheels are different so the clearance under the diff is going to be different even with the same axle. If you measure the distance from the bottom of the differential housing to the ground. Then measure the distance from the bottom of the axle tube to the ground. Then measure the diameter of the axle tube. Add half the axle tube diameter to the distance from the bottom of the axle tube to the ground. From this result subtract the distance from the bottom of the differential housing to the ground. This will give you the difference in hang down between different axles. I'll measure my FF 14 and my 12 bolt, if someone measures a 10 bolt and a Dana 60 we'll be set for rear clearance.

    Your joking about the inch or 1/2" aren't you ?
    Or are you one of the non-off-road Blazers ?
    If you are giving away inches feed her well.

    What I ment was,for me I still seem to hit the underside of my rig from front to back in the high spots and the low spots!So an inch here a 1/2 inch there it all still seams to hit!
    And If you had the opertunity to see my rig in person you would beable to see all the scars and gashes onit from the trail rides!

    I measured the distance from the axle centerline to the bottom edge of the center section for the following axles:
    Dana 44 = 5.25"
    12 Bolt = 5.75"
    Dana 60 = 6.00"
    14 Bolt FF = 7.06"
    I don't have a 10 bolt or a SF 14 bolt to meeasure.

    A 10-bolt should be pretty close to a Dana 44.
    Let's see, if I put a FF14 in to replace my 10-bolt, I'll have to go to about 39" tires to keep the same clearance as my 35's give me now......then the 39's will require a front Dana 60, lower gears, more lift, different rims, longer driveshafts, more power to turn them, bad road manners..........yeah, I don't know why people want to keep their 10-bolts......................

    Let's see, a ride on a flat bed from Moab to Denver, repair 10-bolt or tow to 4x4 shop to repair (wife is pissed). Next year ride on flat bed from Moab to Denver (This time wife gets really pissed and spends all your money on new 30,000. car). Could have saved a lot of money going with the beef from the begining. Yeah, I don't know why people want to swap to a 14 bolt. [​IMG]

    Sorry, I couldn't resist

    If you change from a 12 bolt and 33's to a 14 bolt and 36's it's about a wash under the housing. But you have gained 1.25" under the axle tubes and the ability to climb over larger obstacles with the increased tire diameter.
