Alto Products Clutches & Transmission Products

For over 50 years, Alto has manufactured over a billion friction clutches, steel reaction plates, and powertrain components for automotive, hi-performance, heavy-duty, industrial, marine, and motorcycle applications.

It all started back in the early 1950's as a one-man operation in the basement of a house. Through various acquisitions and the formation of strategic alliances, the once small, one-man operation emerged to become the largest, independently owned manufacturer of automatic transmission clutches, wet friction material and automatic transmission parts in the world.

Alto Products is a world-class manufacturer of wet friction material and steel reaction plates. Alto has formulated friction material solutions for over 50 years. Supplying over 3 billion clutches worldwide, Alto has friction material solutions and advanced steel reaction manufacturing capabilities tailored to meet the customer’s demands. Alto’s portfolio of friction material is engineered and designed to meet a wide range of frictional properties, torque, pressure, and thermal demands under specific operating conditions and oils.
