Grede Holdings LLC, Novi, Mich., announced it was named a 2009 Navistar Diamond Supplier for exceeding the customer’s performance expectations last year.

“As a Diamond Supplier, Grede is among a very select group of suppliers in terms of supplier/customer collaboration,” said Persio Lisboa, chief procurement officer for Navistar International Corp., Warrenville, Ill.

Grede was one of 37 of Navistar’s more than 1,200 suppliers and the only iron metalcasting facility to receive the honor. This is the second straight year Grede has won the award. (Grede has been merged with the former Citation Corp. since it last won the award.)

Grede manufactures components for Navistar’s MaxxForce diesel engines at its Menomonee Falls, Wis., machining operation and its casting facilities in Wauwatosa, Wis., Iron Mountain, Mich., and Biscoe, N.C. It also supplies Navistar with parts manufactured via lost foam casting at its Columbiana, Ala., facility.

Grede Holdings LLC was formed in 2010 through the merger of the former Grede Foundries Inc. with Citation Corp. The company makes ferrous castings out of 13 metalcasting facilities and two machining operations in the U.S. Navistar produces trucks, engines, buses, recreational vehicles, and chassis for motor homes and step vans.
