do you have a six speed or a auto? six speeds only came with 3.42's...autos with 3.23 or 2.73...the code on the autos for 3.23 on the side of the drivers door is gu5 i believe

I had 373's in my auto and the only reason why I did that was b/c I chipped my stock gears...I would stick with the gears if you have the 342's
