Will the Motive 3.42 gears and Zexel Torsen differential from ammperformance.com fit my car?

 

If the gears are for a 7.5" rear, yeah.

Do you currently have a 3 series case? Not sure about Chevy, but BOP (Buick-Olds-Pontiac) under 3.23 was a 2 series, and over was 3 series. You need a 3 series for that OEM Zexel/Torsen lsd.

 

My stock gears are 3.23 so i guess i would have the 3, do u think i shouls get 3.42 or 3.73 gears??

 

I run 3.42's stock, and love 'em. I don't think I'd go 3.73.s Can you get 3.55s?

 

i dunno where i can get 3:55's from that would b so perfect if i could

 

Sorry, I don't see it on Summit for the 7.5" gear.

Is this an auto or stick?

 

I see, auto... go 3.73s
