Re: 8.8in swap

Basically what you do is disconnect your 7.5 rear, drop it, put the 8.8 on and you're done. As far as the other little things I have no idea lol. I believe the driveshaft will bolt right up.

not difficult at all. it's pretty much a direct swap. the stock driveshaft will work with teh 8.8, but while you're there, why not get an aluminum driveshaft to reduce rotational mass in your drivetrain?

Re: 8.8in swap

Im going to say no.

The 05 GT is a different chassis than the 94-04 chassis.

Of course, you can take a lesson from our badass four wheeling friends and just make it a custom install. Line the mofo up, measure twice, and weld it to the car.

Re: 8.8in swap

its very easy just takes a bit of time. If you dont need to reuse your axles its even faster. Just jack up the car and support the frame on jack stands, remove the drive shaft bolts, jack up the rear a bit to remove tention, unbolt shocks and then the uppers/lowerss and it falsl out.

Re: 8.8in swap

okay going on with this swap i wanted to add a gt aluminum driveshaft/ but ive found that they are specific to the type of tranny you have? could a manual driveshaft work with an auto's tranny? why does it matter?

rear end swapping is just a mater of supporting the rear end with a jack with the body on stands. than unbolting rear swaybar, d-shaft, shocks from botton, lower control arms and upper control arms.
