    I did a search but am still a little confused, so here's the question.

    Will a 14 Bolt FF from a 87 K30 bolt into a 91 3/4 ton Suburban 4x4 (came with a 14 Bolt Semi Floater)?

    If not, anyone know what the spacing is for both?


    Something tells me "ThatK30Guy" knows this one. Wanna take a stab at it Wes?


    Thanks in advance guys.

    You'll need to move the perches and shock mounts on the FF. The one ton 14 bolt perch width is 40.5" and the 3/4 ton perch width is 42.5".

    The one ton 14 bolt has staggered shock mounts...but they are opposite of the 1/2 ton and 3/4 ton setups.

    At least your parking brake is a bolt up deal./forums/images/graemlins/smile.gif
