Ford Racing posi lock.

I thought about getting the posi traction unit from rpm outlet. Heres a link. http://www.rpmoutlet.com/musv6fordgear.htmIs it good and is it worth it? Do I need friction modifier and new gears? What wall will I need to go with it? And is the stock diff 7.5" or 8"? I was thinking about going 3.73 gears how much will that hurt mpg? Any help appreciated.

You may want to look into a detrot locker.

GT takeoffs dual exhaust

After doing somemore searching I decided on using a GT exhaust system. From what I hear they are a direct replacement from the headers back and the only thing needed is the hardware to hang the pipe on the right side. Is that all? Is there anything else I should know?

Yeah, they don't use clutches, so it will never wear out. The Locker used to be OEM for the SVO. They were impossible to find whan I bought mine, they only reissued it last year.

You have a 7.5" rear end.

Subtract approximately 1 mpg per 1/4 extra turn. 99+ cars have 3.27s so from that - 3.45 -1 mpg, 3.73 -2 mpg., etc.

I've got the Ford Racing Traction-Lok. Cheapest is at either www.buyfordracing.com or www.GEFracing.com -they average $179 or so + shipping.

If you pick up a Ford Racing Catalogue, you might be able to find a wholesale dealer closer to you so you can save on shipping charges.

You'll need an adapter. Best buy is the adapter from Pacesetter Exhaust -which was $75 at www.summitracing.com

Oh, re: friction modifier -you'll need it you use non-synthetic fluid.

If you use a good synthetic (which WILL help your MPG) you don't need the modifier.

cheapest is usually the junkyard. they're stainless steel, so you don't really have to worry about them rusting out.

If you go to the dealer, you'll end up paying $400+

Are you sure I should take the detroit locker over the Ford racing. Why did you choose it. And are you talking about the pacesetter adapter that requires cutting and welding?

It was so long ago, I don't remember if it requires welding or not.

Regardless, you're going to have to cut the y pipe.

If you're looking for performance and durability, the Detroit Locker is totally the way to go.

If you're not planning on keeping the car that long, or you plan to swap out the rear end with something else down the road -go with a FR unit.

yes.

Use froogle, or call Detriot Locker to see if there's a wholesaler somewhere .. .
