These gears fit Webster or Hewland MK 4, 6, 8 and 9 gearboxes (1 inch diameter layshaft with 6 spline teeth). The "S" Class is the latest, strongest Webster gear design, suitable for 1600 or 2.0L applications.
A sophisticated tooth design, shaving, double tapering, crowning, and center grinding on the pitch circle ensures accurate engagement to eliminate stresses from off-center tooth loading.
The Nuovo series are manufactured using improved heat treating techniques for a considerably stronger gear with significantly better fatigue resistance. Final machining is now performed after heat treatment for improved precision.
Made in USA.
