Straight-cut gearset for A+ gearboxes using the standard 1st and reverse gear. The ultimate for high performance street cars or track day events giving nearly the same close ratios as the original 3-synchro straight-cut gear set. Using latest gear cutting techniques, equipment and some Rover Powertrain tooling the manufacturer is able to produce a money saving way to go for a stronger and slightly quieter product than usually associated with straight cut gears. Gears in this kit are 2nd, 3rd, 1st motion shaft and laygear. Your original first and reverse are to be reused with this set.
A pre-A+ gear case can be modified to accept this A+ gear set. It requires using a grinder or long drill bit to chamfer the shaft hole in the center web of the gear case, as shown in the second photo. This is to allow clearance for the second step of the A+ layshaft. If you plan this conversion, you will also need the C-22A1739 3-step layshaft and the appropriate layshaft bearings 13H9513 (2) and CHM0141 (1).
