What trucks did they come on? Where should I start to look? Any tips? Thanks.
14 bolt semi floaters came on 3/4 ton trucks. 2WD had 6 lugs, and 4WD had 8 lugs. The 14 bolt full floater came on some 3/4 ton 8 lug 4x4 and 1 ton 2WD and 4WD trucks. Every big block, and/or diesel 3/4 ton I have seen has the Full floater. The small block 3/4 tons usually have the semi floater, but the full floater may have been an option on them. I have also seen a 14 bolt semi floater 5 lug, but this was under the 1/2 ton 2WD 88 and up pickups, and 92 and up subs and blazers with the 454 SS package. Not a very common thing though. This is what I have come across anyway. Maybe someone can verify this. /forums/images/graemlins/burb.gif
What year's did the 14 sf come in? I am most interested in the 6 lug version. Any help is great.
Well, not to be an ass, but the best place to start is the "search" button at the top of the page. /forums/images/graemlins/deal.gif
But, as said above - you can find 14 bolt FF and 14 bolt Semi-floaters in various makes and models. Sometimes I wonder if GM had a system to the placement of what axle under this truck, and what axle under the next. If getting a FF from a 3/4 ton 4x4 truck, it will bolt up DIRECTLY to your application. One from a 3/4 ton 2wd will bolt up too, but the shock locations are 2 inches further downward - so they'll have to be moved or longer shocks installed. The 14 bolts from a one ton will work, but the spring perches need to be cut off and re-welded further out. 1 inch on each side out to be exact. Hope that helps, and like I said, do a search - you'll be sure to find answers.

Not true. My old truck is a 3/4 ton 2WD and has an 8 lug semi floater.
Correct.....every once in a while I'll see a Z71(6 lug) with the 14 bolt semi-floater axle. The 14bsf was/is available in 1/2 & 3/4 ton trucks...2 or 4 wheel drive. /forums/images/graemlins/thumb.gif
6-lug 14-bolt (9.5") applications:
88-98 K1500 w/F44 option
88-98 K2500 w/6-lug wheels (same width as K1500)
88-98 C2500 w/6-lug wheels (narrower than K-series)
96-up Savana/Express 2500 w/6-lug wheels (widest of the bunch)
Possibly others, but my expertise doesn't extend into the newer Silverado trucks.
My brotherinlaws got 6 lug version under 86 4x4. /forums/images/graemlins/thumb.gif
Well, there goes my theory of axle finding logic out the window. I just worked on a 8 lug 2WD 3/4 ton with a 14 SF so I have proved myself wrong as well. Looks as if the best way to find an axle, is to go to the yard and look under every chevy truck till you find the one you want. Sounds like lots of fun /forums/images/graemlins/grin.gif /forums/images/graemlins/burb.gif
