I have a Mopar 34 tooth short shaft speedo pinion gear:
29" with 3.55
30" with 3.73
34" with 4.10
38" with 4.56
40" with 4.88
And a Mopar 29 tooth short shaft speedo pinion gear:
I don't recall which chart I referenced, but I bought this for my 33" BFG MT KM1's on stock 3.55 gears and it was dead on.
29" with 3.07
34" with 3.55
35" with 3.73
Tire/gear pairings are from gojeeps' chart. $30 each shipped.
