Our newest STEALTH® Series gears utilize the most advanced gear cutting technology, known as face hobbing. It’s a different gear cutting method that creates a continuous and more consistent cut on all teeth of the ring and pinion at the same time. The heel and toe of each gear tooth are now the same height, which helps create a consistent pattern and improves the tooth to tooth contact.
