Modern transmissions rely on specialized metallic hook rings, and Grover Corporation is a leading manufacturer of new and replacement parts. Automotive customers, makers of heavy off-road vehicles and users in the blower, agriculture and construction rings all count on Grover Transmission Rings.

Although transmission applications require several types of rings, Grover's metallic hook type rings are most frequently found in hydraulic transmissions, hydraulic clutches, torque converters and hydrostatic transmissions.
