10 or 12 bolt?

[chevy_mud_84]

whats stronger,the 10 bolt rear or the 12 bolt rear???? Thanks

they both suck... 10 bolts just suck worse. do yourself a favor and pick up a 14bff. 3/4 ton applications are a direct bolt on.

well thats the thing i just baught an 81 3/4ton chev, to replace my 84 1/2ton..but i havent picked up the truck yet to see whats in it, but the guy seems to think it has a 12 bolt rear end in it. but i always thaught they came with 14bolt rear ends!!

nah, that thing should have a 14bff, or maybe a 14sf, but not a 12b

10 and 12 bolt are about equal in strength....at least with the 30 spline 10 bolts. 10 bolts pinion is a good .3" thicker than the 12 bolt.

About the same. Go for the 14FF. Can be had for $150.00 just about anywhere.
