Differentials for an IFS/IRS setup

[olason]

Hello,

I have been looking to do an all-wheel drive swap for sometime, and I have been looking at the Currie 9" center section found here: http://www.currieenterprises.com/ces...E.aspx?id=3497 as the differential in each end of my project. I realize that it is a big unit, and even with setting the engine back I don't think I will have enough room for that big unit.

Any small stock, but aftermarket supported differentials? I am looking at 600hp - 800hp with more power to the rear end, but a max of 45% front / 55% rear.

My pie in the sky AWD 600hp G-body would be based on a trailblazer SS platform, 400hp stock so shouldn't be that hard to get to 600 and keep everything together. To give credit where credit's due I got the idea from SSAWD's build.

Oh it requires running an LS though and an auto, so if you had a different powertrain planned that won't work...

I have seen that build, my daily driver is actually a Trailblazer SS. I was looking to use a different setup as the Trailblazer SS setup places the differential axle going through the oil pan. Which means the engine is sitting rather high for what I want.

How about the 2006+ CTS-V diff? It is supposed to be stronger than previous years, and it looks way cool with a cooler installed. The S-10 front diff actually holds up reasonably well, if set up correctly and is lightweight. I don't know all the gear ratios for the Caddy rear, but they are both available with 3.73 gears for sure. I am looking at doing the same thing in the Blazer with some aluminum spindles that are more suited to a retro-fit than the Vette pieces.

You could probably lower the engine & diff in the chassis without too much angle on the cv joints. I just don't see you getting the axles any closer to the crank without placing the engine completely behind the axle centerline.

If you want to use an OEM diff. The common options are the Ford 8.8 (Cobra03/04, Expolorer etc) Viper or C4 Dana 44 and the Nissan Diffs. The Nissan R230 is bigger than a 9” Ford differential. HybribZ has had some good topics on Diffs.
