    I have an 86 blazer thats stock now and needs a rearend rebuild. I plan to lift it a total of 5 inches with 35s in the future. I dont think i want to go the DANA60 just because of the trouble to find one and rebuild it. But I was wondering if, since I am going to be lifting the truck in the future, if i should change the gears. I want more torque now, but I also drive the truck on the interstate so I have to be able to do about 70-75 preferably. So should I change the gearing or not? Ohh and if i change it in the rear, do i have to do the same up front? Thanks

    you could find a 14bff for the price or less of the rebuild, most likley will have lower gears. and they usually come with a front 8 lug 10 bolt with the same gears. i got my set for 200 with both axles

    if you already have 3.73(highly unlikely) then you could find a 3.73 14 FF

    also 3.21 was put under some of these

    good luck

    dont even bother rebuilding a factor rear axle. Look around locally at yards, in the nickel ads, the paper etc... you'll find a cheap ff14b somewhere. It'd be a cheap way to re-gear too... just find a ff14b with 4.10s in it. Pretty common and then all you'd have to do is do a gear swap up front. And yes... you have to do both the front and the rear gears... unless you run different size tires front and rear...

    GM corporate 14 Bolt Full Floating axle

    14 Bolts are 8 lug, so you'e either need new wheels or adapters.
