I use to have 3.73s but have recently changed to 4.10s. I had the correct speedo gear installed for the 3.73s and it was just right. Now that I have the 4.10s in, it seems to be off about 10mph. Is there even a correct tooth gear for the 4.10s???

Could this problem also make my tach way off too???

Thanks,

Tony
