    alright i have a 86 k10 (wish i had a blazer, but thats another story) with 10 bolts and 35's, im lookin to run 39s but keep my 6 lug pattern (low budget), what do i need to do to run 6 bolts instead of the 8 on a 14 bolt??? i know i need a semi floater 14 bolt so if anyone could help me figure out where i could get a semi floater if u know what model truck would have one and what kit or supplies i need to run 6 lug and any suggestions if this is a good idea or a waste of my time----thanks fellow wheelers /\RoCk On/\ <font color="black"> </font>

    Why do you "need" a semi-float 14bolt? The Full floaters are (imho) by far the better choice. A full floating 14bbolt is found in 3/4T Trucks. They're also found in some flatbed 1 tons, but you will have to relocate the spring perches.

    As far as semi-floaters, I have never even considered on in my truck, so I'm not 100% sure on the application.

    '86-later 3/4 ton 4x4 suburbans and pickups come with a 14 bolt semi-floater. If you get one from a pickup, it will have to be either an '86 or '87 unless you want to cut off the spring perches and relocate them. Find a K20/K2500 suburban from '86-'91 and you'll be golden. The 14 bolt SF is far better than the 10 bolt...definitely get the SF or FF if you're going with 39's. /forums/images/graemlins/thumb.gif

    To make the search easier, the 14SF was put into produuction in '81 and runs up to current date. /forums/images/graemlins/wink.gif

    You know, that's kinda what I thought. I know I've seen the 14 bolt SF in earlier years than '86, but I wasn't sure when they started putting them under those trucks with regularity, so I figured I'd just say '86.

    Some 14Sf's are 6 lug from the factory, friend had an 88 light duty 4/4 ton and it has 6 lug rear, my 87 3/4ton has 8 lug 14SF. Dont know about spring perches on the 88 though.

    To find a 14bSF 6 lug look for a 3/4ton light duty pickup. I THINK the spring perches need to be moved but not positive. They are only in 88' later trucks though so forget all the other earlier years for the 6 lugger. QUESTION: Why do you want a SF and stay 6 lug. a 10bolt front and a 6lug 14SF is great for a truck that needs a little bit more strength in the rear but it's not really a "strong" combo. With 39's(IMHO) you are out of that "needind a little extra beef in the back" range. You need to go 1ton. My guess is that you have nice 6 lug rims, bit the bullet and sell, find a 1ton set and buy new wheels. /forums/images/graemlins/frown.gif

    Oh yeah, and 6 lugger 14bSF's are going for like 800 bucks around here.

    sorry to kinda hijack the thread, but while yall are on the topic, the 14BFF axles are all 10.5" ring gear, with the angular centersection, correct?

    yep, 10.5ring gear and the pumpkin has no round edges, good looking rearend in my opinion, compared to a 10bolt. /forums/images/graemlins/tongue.gif

    I think of it as an interactive magazine subscription. Who wants to mail off a question and wait 2 years for a lame answer that just leaves you scratching your head?

    Now back to the topic at hand....
