These genuine Hewland gears fit Webster or Hewland Mk 8 and 9 gearboxes (1 inch diameter layshaft with 6 spline teeth). The "M" gears are the latest, strongest gears available. They are even strong enough for 2.0L applications.

Fixed First Gearsets: Using very low first gear ratios in a standing start application (Autocross/Solo II) can break slide-on gearsets, even with an FF1600 engine. These cars should use "fixed first" gearsets (noted below as 1/4 or 1/5) whenever possible. These gearsets have the first gear cut directly into the layshaft itself for improved strength. Five-speed applications using a fixed first gear also need to use a special 2nd gear (noted below as 2/5). Four-speed applications always use standard gearsets for 2nd through 4th.
