This item qualifies for FREE Shipping in the continental United States!

These gears fit Webster or Hewland MK 4, 6, 8 and 9 gearboxes (1 inch diameter layshaft with 6 spline teeth). The "S" Class gears are the latest, strongest Webster gear design and are strong enough for 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 result is a stronger gear with significantly improved fatigue resistance.
