8D-2116: Ring Gear

Description: Ring gears, such as part 8D-2116, are used in the differential system to transmit power from the drive shaft to the axle shafts. All Cat gears have unique metallurgy compositions tailored to specific applications, with special steel formulas that improve impact resistance and ensure uniformity and proper load transfer. Some Cat gears also undergo proprietary heat treat processes to improve surface, bore, and core hardness. The result is greater durability, which means longer life and better performance.
