hey i have a 289 and when taking off it has way to much power for just one wheel spinning .. would it be hard to change it to posi and how much would it cost me? if anyone has done it before.

 

cost me 350 bucks shipped for a complete pumpkin with a locker unit and my choice of motive gears (3.55's). IF you've never done a rear end before, I would recommend takin it to a shop (which will probably cost you another hour or two worth of labor) to have it installed.

 

hey,
Where did you get that for $350?

 

really i cant find one that cheap either so......give it up where you get it at?

 

ditto

 

Is it proper to call a locking "FORD" differential a "posi"? I thought that was GM's trademarked term, and that Ford uses the terms "Detroit-Locker", "Traction-Lock", etc.

Am I losing my mind?

 

Posi is just easier to say, and it sounds cooler.

 

It doesn't sound cooler. This is a chevey term and shouldn't be used on a Ford.

 

Best non-trademarked term to use is "limited slip differential".

It's pretty darned easy to slide the axles out and replace the pumpkin.

I have a Detroit Locker in my 9". If I drove it on the street more I'd probably want the new Truetrac (smoother gear action, compared to the Locker that ratchets).

This is where I got my pumpkin from, although I don't see any available 8" on there site currently. Give them a call though, I believe they manufacture their own reinforced 8" housings and they can pretty much custom build a 3rd member any way you want it.


EDIT: Here is an 8" center section : 8" Posi. WOW, prices went up! I bought mine from these guys' ebay store about 3 years ago.
