Re: who has posi?
You need to give a lot more information to get an accurate answer to a question like that. What engine/trans/gear ratio? 2wd or 4WD? Coils or leafs?
If you're running a stock engine on a 2WD with coils, I suspect you'll fine your stock suspension does a pretty good job of letting you hook up with the posi. |

Re: who has posi?
You are only going to have a chance of axle wrap with a leaf rear end. The coil one won't budge. There was a guy on Pass Time running in the 9's with the 2 link setup. The main thing you will need is a video camera so you can post your burnout. It is required or you will be banned! lol

Re: who has posi?
You shouldn't need anything unless you intend to race the truck. Then the standard mods to help it hook up apply. If it is a coil spring truck there isn't much if anything left to do. A leaf spring truck may need some sort of traction bar setup if you get wheel hop on launch but that would take some serious horsepower in most cases.

Re: who has posi?
My k2500 has posi with those leafs.Although they are stiffer than 1/2t (if that`s what you have) i don`t have any wheel hop or notice axle wrap if there is any.I run 12.50/33s and chirp them when I hit 2nd hard.I don`t do burnouts with it.It will chirp pulling off hard,though.I`m prolly right about at 275 horses.
