1974 K10 1/2 ton Posi
Just as the title says. I have a 1974 K10 1/2ton truck with a 12-bolt open diff. I want a posi in it, and not air lockers. Anyone know a good one to put in, if not a full time. I currently am running 33"x12.5"x15" BFGs and it does no good for me to only have one wheel spinning.

Re: 1974 K10 1/2 ton Posi
Thanks guys. I take it it's a fairly simple swap-in?
Also, spline count for 1/2 K10? I'm not 100% sure. If I recall correctly it's a 8.875 30spline, right? Then I'll obviously also have to know my gear ratio. Last edited by Hewfil1; 12-04-2016 at 12:08 AM. |

Re: 1974 K10 1/2 ton Posi
Yeah you will need to know which ratio you have which would be in the glove box. I've heard good things about the trutrac and personally I had an auburn clutch type lsd that worked well. Will have to setup the gears after install so if you want to swap ratios you are 1/2 way there.

Re: 1974 K10 1/2 ton Posi
Yep no problem it is a Limited slip so it behaves very well on the street. Turns like it did with nothing in the front. I also have a np208 and warn hubs.
