ABOUT

The JEFFco Transmission has more than proven itself on the track and for street use.

The 3-speeds are being used in high horse-powered cars with great success...

The 4-speeds are King at many events. Tom Hargar won the Ozark Super Shifters Championship and won the Lenco Challenge Race with a JEFFco equipped car.

IF YOU’RE NOT PULLING LEVERS,

IS YOUR CAR REALLY WORTH DRIVING?
