1:1 ratio competition straight cut evolution drop gear set for 1275cc engines using A+ gearboxes.
 
If you are looking for the ultimate for your competition Mini's drivetrain loo no further. The drop gear system is normally a weakpoint of the transverse A-series, and helical cut gears can genrate lots of sideload issues with hard use. The use of a straight cut gear system eliminates sideload and with the upgraded materials used on these gears they are even stronger than factory helical gears! 
 
This set includes a 23 tooth primary gear complete with new bushes, 30 tooth A+ idler gear, and 24 tooth input gear. These together create a standard 1:1 ratio.
 
Please note that the primary gear may need to be reamed as the bushings are new and need to be sized to crankshaft.
