Just wondering if anyone on here has done this upgrade yet? If so how much did it cost and what are your current power levels??? I am just curious as i am contemplating doing this upgrade once i step up the power levels considerably once again.

I had thought about it, from a durability standpoint, but ended up doing a thorough Liberty rebuild at a much, much cheaper price.

PM me for more info...

you can't go wrong with Liberty's Gears

great guys, authorized Tremec dealer & repair facility but their real claim to fame is their absolute domination (over G-Force) in NHRA Pro Stock with their 3000+ HP boxes :bowdown:

Can you give me any more info on this ?? I had never heard of a liberty rebuild kit. Is it an upgrade like the gforce kit, or sort of a stock replacement type deal? How much hp/tq is it good for, and how much is it??

I just got an email back about pricing for gforce, basically it would be about 2500 which is alllot for a tranny upgrade. Now im wondering how that compares to the liberty rebuild. Any info is greatly appreciated!!!!

What exactly did you have them do?

Curious cause they did mine too.

Liberty makes a great product (had a Liberty Pro-shifted T5 in my 88 Coupe for a while), but I don't know what Pro Stock Trannies have to do with 10, 11, and 12 second Cobras. :)

More down to our speed....the 2004 NMRA R/S and F/S champoins both used G-Force T5s. The P/S champ (the class between R/S and F/S) ran an auto.

you mean you don't have 3000 HP in your Cobra? ;-)

I said it was their claim to fame, not that it was applicable to us...
