14 bolt axles

[ThreeBills$]

I looked around different forums and couldn't find any thing on the width of a 14 bolt rear end(without abbrievations). I am new to 4X4 and kinda need it spelled out for me. I was wondering if there is a difference in width between a 10 bolt rear end and a 14 bolt rear end. Also, what is the difference between a 14 bolt semi float and a full float? Thanks

14 bolt width will be the same width but the spring perches are different on a van and Dually. To make a direct bolt in you need one from a truck. The semi float axle your tires connect to the axle-if you break an axle the tire will come off. The full float is the stronger of the two. The axle shaft can actually be removed with the tire still on-the weight of the vehicle does not technically ride on the axle itself??

Hope this helps-Someone might be able to explain it better though

I'm sure someone will post the link from pirate4x4 the 14bolt bible. If your looking for a direct swap into you 1/2 chevy get a 14ff from a 3/4ton truck then you won't have to move spring perches. Simi floaters still used c clips and full floats the axles bolt to the hubs. FF from a 3/4ton is what your looking for, fairly easy to find. Do a search on sf vs ff to get all the details.

Umm, no.

There are four widths of 14BFF's, and the perch width differs from 1/2 and 3/4 ton trucks (same) to 1-ton trucks (different) to vans (different yet, I believe).

The Billavista bible has all this, but just for the record, there are a wide variety of 14BFF's, not all of which are suitable for K5's. I got a dually one and had to get a different one, I know
