These are new ring and pinion gears for the Morris Minor and Sprite/Midgets. 4.22:1 ratio with a 9 tooth pinion gear and a 38 tooth crown wheel. This is a reproduction of the original rear axle ratio from the original Bugeye through December of 1968 when the ratio was changed to 3.9:1. This ratio gives the best acceleration of the stock gear ratios from a standstill but does produce higher engine revs with freeway driving. Note: These new gear sets require fitting to the late styled differential housings without the fill plug on the side. They are thicker than the factory type gears.
