VM has manufactured our own high-quality replacement ring gears for the single cylinder Kohler K-Series 9.5" diameter flywheels. The ring gear measures approximately 10.75" O.D. x 9 .25" I.D. and has 105 teeth. When installed on a flywheel it will add about 2 lbs. to the overall rotating mass.
Note: This is not a replacement ring gear for the V-twin flywheels.
