NO you cannot use the stock carrier 3:42's and lower require the stage 3 carrier unless hell has frozen over and im dumb... you have the stage 2

 

I got gm motive 4.10's with an SLP carrier. No problems here...............knock on wood.

Do u have a part number or web site for that carrier??? thanks

 

Shawn What gears do you have in the car now? If you have a 3:?? gear or numerically higher you can install 4:10. If you have anything lower some gear manufacturers also make a 4:10 gear that will work on a 2 series carrier as well I believe Richmond does. The ring gear is just simply thicker. Cost is a little higher though.

 

the rear end is stock i havent touched it yet thats why i was wondering cause i want 4.10 in it for sure.. well if anything ill get a 3 series or find one that will fit a 2

thanks,
shawn

 

Look in your glove box for rear gear codes. GU2=2.73, GU5=3.23. What trans do you have?
