Originally launched in 2005 and used by every Mini Miglia Champion since, the Swift Shift Dog Engagement A-Series Mini gear kit has been a huge success as racers are astonished by its ultra fast, slick gear changes.

Swiftune have optimized the tooth counts, whilst retaining the same ratio sets. The purpose of this change is to decrease the working pressure angles of the constant mesh gears which will help to increase longevity in higher power/torque engines. Other new improvements include maximized bearing support under the main gears by increasing the bearing from 13mm to 17mm. he increase of 4mm per gear whilst not appearing much is a significant percentage increase of over 30% and will significantly increase the resistance to high torque loadings.

Ratios are as follows:
2.143, 1.486, 1.195, 1:1 Also available Super Finished
2.362, 1.564, 1.195, 1:1
