    Doing the 14FF rear soon and wanting to just put a 3/4t 8 lug front 10 bolt. I currently have the 6 lug front 10 bolt.
    What all will swap from one to the other?
    steering arm?
    ext brake lines?
    shocks?
    d-shaft?
    u-bolts and plates?
    swap bar?

    any surprises?

    everything will interchange except for the rotors, pads, and, i think the calipers are different also between 8lug and 6 lug 10 bolt

    Hubs rotors and backing plates are the only difference as long as we're talking about 10 bolt fronts.

    Calipers and pads will go on the new axle. The 3/4 ton pads are thicker but the 1/2 ton pads will work fine.

    One thing that is very important...What is the gear ratio in the 14FF? Gear ratio in your current 10b? IF they are not the same then I would bet you would be money ahead to just look for a 10B 8 lugger with the same ratio as the 14FF and sell your current 10B for whatever you can get for it; then trying to gather all the parts and having a gear shop install a new R&P. /forums/images/graemlins/thumb.gif

    I am in the process of selecting rims (bart supertruckers 15x10) for my 8 lug 10 bolt swap and 14 bolt s.f. If the calipers are the same on the 6 lug vs. 8 lug will grinding still be needed to run a 15" 8 lug rim? Also if you run 15" on a 8 lug set up can you still get the wheel balance weights to work.

    The calipers are the same, but the rotors are different diameters....the 8-lug being larger. The calipers are mounted further away from axle centerline to acccomodate this. You will need to grind to fit 15" rims.....how much depends on the rim's backspacing. /forums/images/graemlins/thumb.gif

    Wheel weight that are mounted on the wheel lip(not the stick-ons) will work fine. /forums/images/graemlins/thumb.gif

    Beast 388 is absolutely correct.

    I went with 4 1/4" of backspacing. You'll be shocked when you see just how much grinding is necessary to clear a wheel with that much backspacing.

    That said I have no regrets. I like having my tires tucked in. Especially with 16" wide tires, you can never have enough backspacing.

    The Bart super truckers have a 3.5 b.s. Guess that will be about 1/2 the caliper /forums/images/graemlins/thumb.gif I still am trying to decide the pros and cons of running steel 15" black wheels /forums/images/graemlins/smile.gifusing my current 33x12.5x15 or stepping up to 16" aluminum bling blings /forums/images/graemlins/pimp1.gif and new tires.

    nono, its a totally different 10B 8 lug with gears that match the 14FF. I was just making sure that my brake lines, steering arm and d-shaft would all interchange for when I go to swap the 6 lug to the 8 lug 10B. I normally get these hidden surprises that nickle and dime me to death so Im trying to plan ahead.

    Will 16x10 wheels with 4.25"BS fit the 10B 8 lug?

    I guess Steve needs to save server space and dump well writen stuff like this http://www.coloradok5.com/8lugconversion.shtml cause nobody looks at the front page. /forums/images/graemlins/thinking.gif
