Hey guys. I have a 2001 WS6 Trans Am. So like the title says. Does anyone know if 4.56 gears will fit in a stock rear end?

Thanks in advance

As long as you have a 3.23 or 3.42 gear now you can do a 4.56. Not sure if they sell a thick gear set for 2.73 geared cars

Richmond has 4.56 gearsets for both 2 series(2.73/3.08) and 3 series(3.23/3.42) carriers for the GM 7.5/7.625 rear end.
I ran a 4.56 rear for 4 years in my 98Z A4. I wouldn't recommend 4.56s' for an M6. I've currently got the OEM 3.23 rear end in but the 4.56 rear end is going back in shortly.
