    My buddy has a '98 4x2 chevy pickup. He is looking into possibly upgrading the rear axle to a 14bff or a sf. Can the fronts be changed to 6 or 8lug easily? /forums/images/graemlins/thinking.gif or would he have to go with a converter spacer ring thingamabob?

    I realize this forum is for 91 and older but I think there is much more knowledge floating around here than elswhere. /forums/images/graemlins/cool.gif

    im curious on the newer trucks, can you swap hubs on them from 8 to 6 ?
    are the CV shafts all the same length and splines and such ? it is IFS CV shaft type front, right ?

    The C1500 can be changed into a 6-lug C2500 by simply changing the front rotors and the rear end. That gets you into the stronger 14SF (9.5") /forums/images/graemlins/thumb.gif

    8-lug is more involved. The frames are built differently to hold the beefier suspension. You'd be looking at a complete frame swap to do it right.
