Mini Drop gear set, straight cut, 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.

The Evolution gear sets are all built around a 30 tooth idler, which means that to change ratios, only the input gear and/or primary need to be changed to accommidate a wide variety of ratios.

Idler gear is also available with a Timken bearing, order part number C-STR30/TIMKEN, this gear fits into the gearbox and flywheel housing without the standard bearing. This does NOT fit the latest A+ type with larger idler bearings
