Re: full floating 14 bolt

if it is out of a 1 ton you need to move the shock mounts and the spring pads.

for ground clearence you can cut the bottom lip off up to the lowest bolt hole.

Also will likely need a hybrid u-joint to get driveshaft hooked up. Neapco #21153 is Kragen/Shucks/Checker or Napa #447 are the part numbers for the 1310 to 1350 joint

Re: full floating 14 bolt

I didn't get all the info when i started reading his first post, but are you saying that the 3/4 ton SRW and the 1 ton SRW 14bff's on the pick-ups are different?

The 1310 to 1350 conversion u-joint is the Napa #348. /forums/images/graemlins/deal.gif

But the correct conversion joint that he should need is the #447, unless his stock shaft uses the S44 joint. In that case, one of the guys with a Neapco book can chime in and list the right one. /forums/images/graemlins/waytogo.gif

The axles (excluding the brakes) are the same. The difference is the shock tabs and spring perch locations. The 3/4 ton axles are a direct bolt-in for a 73-up 1/2 ton. They share the same 42.5" center to center spring perch spacing.

The one-ton however, uses a spring perch spacing of 40.5".

So, 55 willy is correct, if the 14BFF is coming out of a one-ton, the shock tabs and spring perches will need to be moved to bolt it into his K5. /forums/images/graemlins/waytogo.gif

Re: full floating 14 bolt

63-72 2wd 1/2 and 3/4 ton also have 42.5" pads, just that oen shock is mounted opposite way from 73-up

the only 2wd before 73 that are not 4.25" pads are the Longhorns starting in late '68 and ending in 72


tell napa what year and series the 14 bolt FF axle is from and what year and model your truck is that the axle is going under and they will hook you up with the right conversion U joint
good luck

Re: full floating 14 bolt

My 14b ff out of a 91 crewcab bolted right in on my jimmy the only difference was the shocks I used the 205 out of the crewcab and part of the drivshaft too because there was a 4 in lift installed on the jimmy so the u-joints were no bigge the cheapest locker I found was a detroit try youre local gear shop mine takes good care of me because I also run a fleet of tow trucks witch means we buy alot of parts so they cut me good deals on my personal stuff... /forums/images/graemlins/crewcab.gif /forums/images/graemlins/k5.gif /forums/images/graemlins/hack.gif /forums/images/graemlins/weld.gif
