Title: 3.45's for a 7.5 -- Disregard, bought new.
Post by: V8Demon on January 23, 2008, 01:03:48 PM
Lookin for a bit of an upgrade on my 7.5, but not quite ready for 3.73's as to the car getting a fair amount of highway miles still (4000 a year or so). So if anyone has a set of 3.45's and the speedo gear to make them work with an AOD and stock size tires let me know. Aint much more than the 3.27's I have, but unfortunately they don't make something like a 3.55 for a 7.5 and this rear end is rather built so....

Do you mean 3.45s? I've never heard of 3.43's for a 7.5"

I had two a few moths ago (7.5 TC rears)and ended up tosing one out at the s yard,and giving the other way.I tried for 3 months just to give them away.I'll look around for some gears for you.

Paul I have the original 7.5 in my bird I believe I have 3.55 in it. Is that possible.
I plan on upgrading to my 8.8 t/c rear w/3.73s.
If you willing to wait the old one is yours.

You have 3.45's which would be what I need.  3.55's do not exist in 7.5 size...

Kitz, I just need the gears and speedo gear.

3.45 Cool I assumed they were 3.55 by spinning the driveshaft and watching the tire so by putting in my 8.8 and 3.73 I will see that much more of a difference

Go with an 8.8 and you can have the 3.55s that will come out of the Sport for the cost of shipping.I'll need a few weeks though.

NO!  LOL!  My Powertrax locking unit is rated for 800 Lb-Feet of torque.  My axles are stronger than stock too.  And the Locker gets rid of the weakest link in the 7.5 which is the spider gears IMHO....

Too much in this rear right now....If it should happen to grenade at some point though...

Paul,what do you want to pay for gears?I really won't have a need for this rear that I take out.It would be a shame to break it down though.
