Ok so I have a 3.42 rear end in my blazer. peg leg. I want a posi rear end. Where can I get one. The reason why I'm asking is that my driveway is concrete then at the end there is a drop off on each side and you have to be very careful not to run off the side when backing out. Well it was dark tonight and I was talking on the phone not paying attention and ran off the side. first time ever, and I feel like an idiot. Well of course it only spun the tire that was hangin off the side. Would it pull itself out with a posi rear end since the other tire is firmly planted on the concrete? What are the specs onthis rear end. I know it's a 3.42, GU6.But is it 28-spline 7.5 or what? which brand should I get, where can i get one?Could someone just tell me, "get this one"

 

to answer ur traction problem yes a posi will spin the other tire a posi spins both tires instead of one like what we have and also called the one tire fire for starters i would call summit racing or check them out online they have a very knowledgeable staff and can help in ur decision for what lsd u need and how much, it just comes down to what ur going to do with it and how extreme you want to get.

 

As far as I know, you should have a 28 spline axle, with a 7 5/8" 10 bolt rear end.

The posi will work pretty good for that situation, but you have to get a little bit of wheel spin...



Oh! And don't talk on the phone while driving, lol
