WTB 14 Bolt Semi Float Differential
 
Looking for a 14bsf out of an '81-'87 4x4 3/4 ton, preferably with 3.42 gears and 11 inch brakes. Bonus if its out of a 4 speed truck so I can also get the driveshaft.

Please let me know what you have.

Thanks,

Danny

I have what you are looking for the only difference is mine is a full floater and a posi. The gears and brakes you want no drive shaft, came out of 91 suburban.

With the 10.5" ring gear? I'm looking for the 9.5" ring gear differential as I'm trying to upgrade my 1/2 ton and keep 6 lug wheels.

Are you still looking for this rear differential? I might have one. Have to pull the cover and check the ratio and check the brakes. It came out of an 86 GMC 2x4. Thanks, Ken

Ken,

Sorry for taking so long to get back to you, I'm in the middle of moving to GA.. I've already found one. Thank you though, Danny

OK, glad to hear it. Shipping would have been a monster on that anyway. BTW, did I understand your post to say you can put six lug axles in this rear end? Thanks, Ken

Re: WTB 14 Bolt Semi Float Differential
 
It's my understanding that there are two ways to get a 6 lug semi floater. Re drill the shafts and drums on an 8 lug to 6 for a squarebody housing which is what I intend to do. Or find a 6 lug version out of a GMT400 truck and move the spring perches and shock mounts. Since I can't weld I figured it would be easier to get a squarebody housing and take the drums and shafts out and have a machine shop re drill them for me.

Thanks,

Danny

Why would you expect this 3/4 axle to have the 14BSF (9.5" ring gear) 6-lug (you may be right, I'm not sure)? There are some other places to be looking for a 6-lug 14BSF. If you want a 6-lug, look at the 88-98 GM-1500s with a GVWR of 6,600. It's important to know whether it's a 2wd (65" WMS-WMS) or 4wd (70" WMS-WMS), because the widths are different. Also, starting in 2004, you could get the 6-lug, 14BSF in the Vortec Max 1500. I'm not sure what the width is on those. You might need a conversion u-joint for the driveshaft. Curious enough, there was actually a 5-lug 14BSF in the 454 SS trucks built between 1990-93. Anecdotally, there may be some 6-lug 14BSF in the mid-90s 2500 vans.
