8.8 posi

nightrunner · April 10th, 2007, 04:27 PM

i have a 8.8 rear with 3.08

i want to add a posi unit and 3.73 or 4.10

what the cheapest best way to do this or should i go with a whole new rear

from say junk yard

just buy the new ring and pinion set. Better look into a new rebuild kit with shims and bearings etc. Altogether it will run you about $250 or so.

There are alot of places to buy them. Check out www.brenspeed.com

I thought the 8.8 was posi?,or limited-slip? anyway whats the difference

Rustbelt · April 10th, 2007, 06:24 PM

you might have a limited slip. what is your axel code? if it is a "z" you have a 3.08 w/ ltd slip. if it is a "y" you dont have a ltd slip.

its cheeper to rebuild the ltd slip than to buy a new one.

whats the difference limited or posi?

nightrunner · April 10th, 2007, 07:57 PM

well doing a burnout only the pasenger side tire spins

It is not a limited slip its a single track rear with 3.08 out of a 92 mustang my gues a 4 banger i was under the impression that ford put limited slip in all there 5.0 stangs or am i wrong

so it is cheaper to build this rear and ad the limited slip and gears

or try to find something drum to drum allready setup

cobraetti · April 10th, 2007, 08:03 PM

so, limited-slip both tires will spin at the same time. I got mine with 3.73 gears for about $250 at a junk yard

well the trac loc could need a rebuild too

nightrunner · April 11th, 2007, 01:11 AM

yeah that what i think is wrong the clutches are gone in this rear

thanks

+1 on the trac lok needing a rebuild......they have kits to rebuild them at the ford racing website. 50 buck for a regular kit or about 110 for a carbon disc kit

Darren E · April 11th, 2007, 12:37 PM

you could use f150 clutches in rear they are stonger also i think you can add an extra one to make the limited slip a little stonger where both tires will spin
