I have a set of 3.73 gears from my rear when I had the pinion bearing done they also changed the gears to a much more friendly 3.42.
My 3.73 gears are much thicker than a friend has for his gear swap on his T/A.
My question is it it a carrier difference on why the gears are a different thickness?
If so which carrier is thicker in the ring gear a 2-series or 3?
Thanks

Of the same ratio gears; The 2 series ring gear is thicker than the 3 series.
3.73's to 3.42's made a big difference?
