An Eaton or Ford Racing TRac-lok will set you back close to $400. Labor to install it will be about 4 hours for your application at whatever rate the shop charges. You should also install new carrier bearings with the installation, about $20 each.

I checked on this when we had originally planned on restoring my old blazer. To change over to posi. with new gears since we wanted a different gear ratio and whatever else was going to cost about $950.

That is where I live though so the price of course is going to vary but hopefully this will give you an idea.

Thank you , this will help !

Also which is the most bang for my buck! I have heard that the Detroit locker (ratchet) is one of the toughest (also i don't care about the noise it makes) but if you know of a brand that would be something i should think about ? I'm new to the strip and im hoping to run maybe 14 's , it is a heavy car thou. Thanks allot

Positraction is a marketing term used by GM for their limited slip differentials. They are the same thing. LSD's come in several flavors. TorSen for TORque SENsing (helical gear type), clutch pack, ratcheting, and air/electric lockers that I can think of off the top of my head. There are also spool type setups, but that just locks your axles together and I don't think you'd like that on the street. If this is just a straight line car, you might be best served strength/money wise to go with some manner of electric locker setup. Open diff normally but you lock the axles together when you're ready to go. Commonly used for 4x4 trucks, I suspect with that rear end you'll be able to find a kit to go to it though.

The ford posi units tend to wear out quick. I have a detroit locker and love it. Its a little noisy but you will get used to it.

I put a Powertrax (Lock-Rite) locker in my 9", works great and quieter than Detroit Locker. Paid $400 for the diff. , $95 for bearings and seals, and $100 to assemble 3rd member.

Sounds like a plan

I think i like the idea of the Lock-Rite or the Detroit Locker i don't really want to have any electrical if i can help it, and would enjoy some of the benefits of having lock up ( when i want it) ! Thanks guys for the help !
