31 Tooth Idler Gear Pre A+ Mini & Mini Cooper S

JACK KNIGHT 31 TOOTH IDLER GEAR PRE-A+ Straight cut drop gears are the most durable arrangment that can be fitted to a transverse A-series powerunit. These 3 gears are responsible for transferring all the Hp from the motor to the gearbox, so their longevity should be a top priority for any serious engine builder. In addition to the durabilty of a straight cut arrangment you get the added benefit of less Hp loss due to reduced side loadings in this critical area, which in turn minimizes the wear on the idler thrust washers.
