    i've read lots of talk of it but want to hear from people who have done it. main questions are: what are the common r&ps in the semi floater 6 lugs? did they ever come with 3.42s? this is what i'm currently running and don't want to get into the front diff. any brake line, e brake line or driveline issues to know about?

    not interested in going solid front axle at this point. this is a daily driver and want to beaf the rear for mild towing and hauling tools.

    I put a 14 Bolt SF in my 86 Sub and the gears were 3.42, most are that come in the six lug, some are 3.73 though. It should be a direct bolt-up in your case, check the spring widths, if not cut off the spring perches and put new ones on. The lug bolts are slightly larger because its a 3/4 ton axle. It bolted up fine with my stock driveshaft and a 4" lift, I don't think the yoke is any closer. I had to swap the brakelines and e-brake on mine, I doubt you will. If so I just took them off my 10 bolt. Better brakes, and I got a full width axle unlike the 14 Bolt FF. I also had the shock mounts cut off and rotated up to increase ground clearance, and it gave the shocks less angle. Steel braided brake lines are also a worthy investment.

    Not first-hand info, but my boss used to do it on ex-cop K1500 Burb's he fixed up and re-sold. The cops would sell 'em off after the 10-bolt blew up. /forums/images/graemlins/wink.gif

    3.42 and 3.73 are the most common ratio. Make sure you get the rear end from a 4x4, or the track width will be wrong and 265 tires will rub the springs /forums/images/graemlins/eek.gif The spring perch widths are the same.

    The 14SF doesn't have sway-bar brackets. You will have to go without the swaybar, unless you're handy with a welder. The driveshaft for a 14SF is 1/2" shorter than it is for a 10-bolt. None of the ones he did got shortened, there was enough clearance.

    What do yo umean full width, unlike the 14 bff? The semifloater is just as narrow.

    Some light duty C2500's came with 6-lug 9.5's, and they were a couple of inches narrower than the 4x4 axles. I put one on my 93, and it bolted right on but the track was narrow. I ran 265's on stock wheels and they didn't hit but it was close.
