Option-6 Speed :(fig. 1).
The design of the Option-6 Speed (fig.2)  conversion takes a number of factors into consideration. Primary in its design is the final cost. The utilization of existing VW transaxle parts reduces the cost while expanding the number of gear ratio choices unavailable. Any pinion shaft or mainshaft that is 020 compatible can be used in conjunction with the Option-6 kit. The fifth and sixth gear sets are modified as part of the conversion cost by us.
The two gear sets may be supplied by the customer (any 020 5th -.71, .75,  .80,  .85,  .89,  .91, 1.05). If one or both sets are supplied by V.L. Enterprises, they will be charged in addition to the kit price.

The Option-6 upgrade will cause the 020 transaxle to increase in length only 1.6 inches, or approximately 40mm.  Excessive transaxle length  can interfere with the movement of the left wheel. In order to reduce the length to a minimum, V.L. Enterprises designed a unique
mainshaft extension (fig.3). The patent pending design places the stock VW throw-out bearing  inside the mainshaft extension rather than after the extension. This significantly
reduces the overall length.
