For sale is an excellent quick change gear set #4 with 24 and 31 teeth. This is set in a 4.11 ring and pinion rear end this yields a final ratio of 5.32 and in a 4.86 ring and pinion rear this yields a final ratio of 6.27. This is a 10 spline gear and in excellent condition. Thanks for looking and as always I combine shipping when possible.
