    Any body know if 15" 8 lug rims will fit on the 14bff over the 13" brake drums? The 13" measurement is for the brake shoes though,the drum is bigger, just not sure how much.

    Thinkin about doing a comversion to rear disk, will the rims still clear without much modifying?

    I am wondering the same thing...will they fit a disk conversion...and to add a little (trying not to steal) to your question...will 15's fit 3/4 ton front breaks? whats needed?

    Yep, piece of cake. I had to clean up one caliper to fit the 15 X 10's on my 14BFF with rear disks. I would go disks if I were you....easy and well worth it. BTW, my rims have a back spacing of 4.25" /forums/images/graemlins/waytogo.gif

    As far as I know there is no clearance issues with disc or drum. /forums/images/graemlins/thumb.gif I run 15x10 with 4.25 backspace on my 14B with discs. There is more clearance on the rear than the front. This is for steel wheels though. Aluminum is a diff story......

    Yes 15" rims fit 14bff's no problem. the only thing you have to worry about is the front axles. calipers. the rear clears easy but you have to make the front fit with the grinder.

    with disks you might have to do some caliper grinding depending on how much backspacing you have /forums/images/graemlins/waytogo.gif
    no problems with the drums...

    [/ QUOTE ]

    Just a FYI 3/4 ton and 1/2 ton front ends are basically the same. The 3/4 ton just has 8 lugs. It's when you go to a 1 ton D60 that you have caliper clearence issues with 15" rims.

    The 3/4 ton front ends are basically the same but the caliper support/backing plate is a bit larger. Most people will have to grind a bit to make 15" wheels work on a 3/4 ton front end (depending on the wheel back spacing).

    Finally seeing the light Tj, from what I see on here the reason people run 15" rims is for the larger available tire selection /forums/images/graemlins/thumb.gif

    Re: 15\" 8lug rims on a 14bff?

    If you want to run 15's on 3/4 ton you WILL (most likely) need to grind. If you run 4 1/8" back space you will have to grind a fair amount on the backing plate AND also the caliper. Trust me I know.

    If you run less then 4 1/8" BS (numbers closer to zero) you have to do less grinding the less you run.

    That is incorrect. /forums/images/graemlins/deal.gif /forums/images/graemlins/dunno.gif

    The 3/4 ton rotor is larger in diameter. Because of this, the caliper is further away from the axle centerline. This is where the interference comes from.

    Like Harley said, the amount you have to grind depends on the amount of backspacing you are running. I had to modify the caliper support AND grind the caliper to fit wheels with 4.25" BS.

    Re: 15\" 8lug rims on a 14bff?

    Seems to me since i have to buy wheels anyway, it would just be easier to go ahead and buy the 16"wheels then???
    maybe /forums/images/graemlins/pimp1.gifsome /forums/images/graemlins/pimp1.gif17" /forums/images/graemlins/pimp1.gifor even 18"s /forums/images/graemlins/pimp1.gif

    Less work and headache, and anyone who knows me,,,,PAUL knows i don't like alot of work. /forums/images/graemlins/grin.gif

    naw i'm just gonna stick with the 16's and just deal with those tires when that time comes.
    Thanks all for the responses and the advice/help.

    Re: 15\" 8lug rims on a 14bff?

    Ahh then I was misinformed. I was told the 3/4 ton D44 and 1/2 ton D44 were identical save the 8 lug rotors.

    I would stick with 15" rims but if you do go bigger stay away from the 16.5" ones.
