So i've been researching doing a top swap on my 02 SS this spring/summer and found alot of info. But there seems to be no clear answers on the axles needing to be swapped or a hybrid of sorts from the NA car to a supercharged car.

So if i already have the 4t65 trans and i do a top swap and i keep the stock trans no hd diff install. Do i need to swap axles? is there something that changes or interferes with the axles on a top swap?

Kinda confused here, and yes i have used the search function, many times...

 

Top swap doesn't need any axles changed

 

Your current axles will be fine. I think you can keep the same axles even if you switched to an L67's 4t65e-HD transmission, or upgrading yours to have an HD differential.

 

ok thanks for all the help
