Gt rear end

I hear about how you can put a Gt rear end on a v6. What's the benefit from this? And what do I have to get to do this? The whole rear end? Need info on this bc I'm planing on doing this

Re: Gt rear end

Well there's definitely a benefit...actually more than one

The GT's rearend is 8.8" compared to the v6's 7.5". The larger rearend (ring gear) is much stronger and capable of handling much more hp, or stress.

The 8.8" comes with a traction lok and 3.27 gears. The standard tlok will allow you to do 2 wheel burnouts and give better traction/launches.

The 7.5" has the open differential, which allows only one wheel to spin. The gearing is the same too, 3.27.

The 8.8" will bolt right up in place of the 7.5". The GT's had quad shocks as to where the v6's did not.

The chassis brackets are not on the v6's but the threaded holes for them are. So if you can get the brackets from the same car you get the rearend from do it. You can get brackets from cars as far back as the 80's (fox bodies).

The only reason you wouldn't want the quad shocks (axle dampers), is if you get aftermarket LCA's. They come with much better poly bushings that tend to eliminate wheel hop, which is why the quad shocks were there in the first place.

To piggyback on the original post, what are the benefits of an IRS upgrade? Which is better, IRS or 8.8?

It's a matter of opinion. IRS is a novel thing to make you think your car handles better in my opinion.

It does ride better and give better angles for the rear tires, but a solid axle car can handle just as well, if not better with current technology.

yes.... direct swap in

you have big plans for the future? if anything past 350rwhp then yes upgrade, if not just put a posi in your 7.5.... with the unneeded (for anything within normal build standards) extra strength of the 8.8 rear comes an extra hundred or so pounds.... would slow you down more than help honestly

i have the cheap FRPP T-lok in my 7.5 and it has been holding up just fine to 242rwhp lol

Re: Gt rear end

-_- that would have been worth the mention in the original post in asking if the swap is worth it.........

is this just an "idea" or a plan?....

Well I know I've been flip flopping my ideas, but after much research- I'm just going to get a supercharger from American muscle that's easier than swapping. I been wanting to do something to get to at least 300 hp. Supercharging is what I wanna do.

---------- Post added at 05:41 PM ---------- Previous post was at 05:38 PM ----------

So my new thing to research is the supercharger. I have a question what should I modify for 11 psi?

Here's the site. http://www.americanmuscle.com/procha...e2-9903v6.html
