    Yes, I did a search. I figure 20 minutes is a good search time. Anyways, I know this has been discussed here before, but my search never got me the exact question and answer I need, soooooooooooooo...

    If I go to 3/4 ton 10 bolt up front, and a 14b SF rear, will I just be able to buy 8-lug 15 inch wheels, or will I need to upsize the wheels to fit (and tires too!!!). I'm just about ready to do this swap, getting the 10b in a week or two, but if I need to get new tires and wheels, the axles will sit in the garage until I can cough up enough dough for the rest.

    Thanks Guys

    They will fit the 10 bolt front with some grinding. You will have to run the steelie's like everyone else though. Aluminums won't fit. I can't say 100% that they will clear the 14bsf, but I am pretty sure they will. They clear my 14bff brakes just fine.

    you can run 15's if u have enough back spacing on the rim. but, i wouldn't recomend it because it puts more stress on the lugs.

    It is the ball joints/bearings that take a beating. I have ran with 2.75" BS for 3 years with no problems. You can fit 4.5" BS with enough grinding. The tie-rod usually rubs before you run out of meat on the calipers. The lugs have no problem taking the abuse. (8 lugs at 9/16 = 1.987²" ->area at major diameter vs 6 lugs at 7/16 = .902²" ->area at major diameter)

    On my rear I have these steel spacers that allow the use of 15's, and the front is ground down just enough to clear the rim, and everything lines up as the same track width. i have not broken anything yet....

    Ok here is what you need to do.
    First off your K5 is running right? and ready to wheel as is.
    Buy that 10 bolt w/ Detroit locker:grin: put it in the grage. Sell you 2 Semi floters
    for approx 50-75.00 then get a rear 14 bolt 3/4 ton w/4.10 gears. you can get one local for approx 150.00 dont wory
    about the brakes I know a guy that is going to rear disk and he will give you the brakes off his 14 bolt or free. Ok now save you money and be a for sale ad whore you can get a Detroit for about 200-250.00. spend 25.00 for a u-joint. Now for wheels I will be selling my wheels and tires in the summer time
    I will cut you a good deal. now if you want 15 inch wheels Discount sells them for about 55.00 for 8 lug 15x10 2.5 to 2.75 BS you will have very little caliper grinding. Now once you have all these parts you can bring your K5
    to the shop I will help you installl it all. Just think about it yes it wont been under the truck right away but if you do it like this over the next 5-6 mo the wife does not get all pissed off and you will be ready to rock in 2006.
    Or just but it all now and I will still help you.
