Don't waste your time going to 4.10's if you've already got 3.73. You need to go a least 2 steps up or down when changing gears, otherwise its not worth the expense. You won't notice that much difference from 3.73 to 4.10. If your 2wd try 4.30's, if 4x4 then go to 4.56 cause they don't make 4.30's for the front diff
