Forged Knuckles

The FreightCar America Parts ‘Diamond’ Forged Knuckle for Type E and E/F Couplers has been M-216 Certified by the Association of American Railroads Coupling System and Truck Castings Committee.

Our Diamond Knuckle minimizes failures and replacements, and it will keep your trains moving with increased reliability and fewer disruptions. Our Diamond Knuckle is uniquely stronger than cast knuckles in a number of areas, while still performing as the key fuse in the coupling system.

Innovative, patent-pending design
Weight parity with castings
Over 2.2 million fatigue cycles in testing: 3.7x the AAR minimum
