    I've recently bought a military pick up /forums/images/graemlins/peace.gif; what do I all need, to change the axels swap in my K5 '87 ?
    Which gear ratio is in the 1 ton axels?
    Which locker is in there?...and how does it works?
    Which maximum tyres size can I use with this gears?
    My motor is 350 TBI...
    Sorry for all these questions... /forums/images/graemlins/ears.gif

    If it has a 350 TBI in it then that has been swapped in. It should have a 6.2 diesel. If its a true CUCV it should have 4.56 gears and a detroit locker in the rear end. The detroit is locked whenever you are on the gas. Tire size is relative but a 37 would be good I think.

    it should have 4.56 gears with a detroit locker in the rear. the spring pad width may be a little different, can't remember tho.

    The front axle will be a direct bolt in using all the parts off of the donor truck. The rear axle will require moving the spring perches and shock mounts /forums/images/graemlins/thumb.gif Other than that it should be fairly simple.

    Where are you located... If you are close to the PNW I'd always be interested in helping you "dispose" of the left overs /forums/images/graemlins/whistling.gif

    the spring perches need to be moved on the rear axle and you need to do something with the shock mounts as well!!! /forums/images/graemlins/weld.gif

    Most of everything has been said. You may need to modify your existing drive shafts a bit. I believe that the axles from the CUCV are larger than what the k5 uses. 37 inch tires work great for that gearing!
