For sale is a very good Winters #8525 quick change gear set with 20 and 22 teeth.  This is set 25 and in a 4.11 ring and pinion rear end this yields a final ratio of 4.53 and in a 4.86 ring and pinion rear this yields a final ratio of 5.34.  This is a 10 spline gear and very good condition.  Thanks for looking and as always I combine shipping when possible.
