EVOLUTION 1340:  5 SPEED TRANSMISSION
The EV Big Twin 5 speed gear box has been around since 1984 but the growing number of modifications for the 1340 engine continues to create more interest. In addition to close ratio first gears, Andrews Products also makes stock replacement gears for 1st, 2nd, 3rd, 4th and 5th gears. All Andrews Products 5 speed gears are made from high nickel alloy and heat treated and shot-peened to give maximum durability and strength. Also, where applicable, lead-in ramps have been machined into most gears to improve shifting and reduce wear on drive dogs and drive slots.

Includes Close Ratio First gear (counter & main), Second gear (counter & main), Third gear (counter & main), Fourth gear (counter & main), Fifth gear (counter & main), Countershaft & Mainshaft
