    Is there any way to get or convert a 14 Bolt Axel to a 6 Lug Chevy Pattern. I was told a few years back that the 90-93 SS454 Trucks had a 14 Bolt in them and so did some Heavy Half and Z-71's around the same time. Any help would be appreciated.

    <font color=blue>You can have 8 lug SF shafts filled and re-drilled to 6 lug then get 6 lug drums, or get a 6 lug axle from a Z71. You'll have to move the perches and shock tabs on any SF so you might as well get the one that came 6 lug

    The CK5 lists own "Donovan" does this conversion for 14-bolt FFs. I talked to him today about this for my own K5....

    Send him a PM and he can give you all the details.

    I was very interested in the same 6 lug 14 bolt custom axle you're talking about. I searched around on the internet and found 2 places that do this...
    I think Drivetrain.com will only weld on new billet ends to the tubes, where i think ORU presses in a whole new axle tube.
    These are 2 emails I got reguarding the 10.5" ring gear 6 lug custom 14 bolt rearend...

    Give Brent a call toll free at 1-800-216-1632. He can review your options and price &amp; design techniques with you.

    Hope this can help.

    A full floater converted to 6 bolt ? Do you really mean the 10.5" FF axle ?
    Then what do you do with the big floater hub ? You cant slip 6 bolt wheel pilot holes over a 3/4 FF hub, it just too big diameter.

    Also, some the 3/4 ton 14 bolt 9.4" semifloaters were 6 lug, btw. most were 8 lug though.
    I never knew about this til a couple months ago.

    Greg is right...someone made it work. Do a search on the main board. The hub and axle flange are machined down and cap head screws used to retain the axles. You have to use aftermarket 6 lug wheels because they have a bigger center hole (to fit toys).

    These places cut off the ends of the tubing or press a whole new axle tube into the 14FF housing, and they convert it to a semi-floating design with the 6 on 6 1/2 lug pattern.
    Its basically the 14bolt 10.5" ring gear center section with custom 33 spline semi floater axles. (Like a 12 bolt with the C-clip eliminator) I believe they use the 1/2 ton drums or you can pay extra for the disk brake setup.

    very interesting indeed, that sounds like alot of work. but why have a big mean pumpkin with reduced hubs and less wheel studs?
    Isnt that a strength issue ?
    Whats wrong with 8 bolt ?
    I have a feeling that I ammissing out on something, here.
    Good to learn new info, however :)
