OE posi
 

How good are the GM model posis I bought a used one for 175 bucks and am planning on installing it, but dont want to have to buy another next year you know.

Clutches inside of those things should be the only thing you need to worry about. They can be replaced, summitracing.com has kits to replace the clutches, but that should be the only part that really needs to be looked at. I'd definately put the posi aditive in the fluid, but besides that, I'd install it and then if it isn't posi'ing up, I'd replace the clutches, unless you wanna throw the money at it before seeing if it's a true problem, either way...

I will try your advice. I dont want to throw away the money invested. Thanks for the reply.
