Navistar International Corp. announced it has appointed Bill Kozek as president of the company's North America Truck and Parts business. He succeeds Jack Allen, who was promoted to chief operating officer last month.

Kozek joins Navistar following a 26-year career at Paccar Inc., where he most recently served as vice president and general manager of its Peterbilt Motors Company.

Kozek will report to Allen and serve on the company's senior leadership team.

Kozek had served as Paccar vice president and general manager of its Peterbilt division since January 2012, responsible for all aspects of Peterbilt's U.S. and Canadian operations. He served as vice president of Paccar China in 2011, where he was responsible for purchasing and business development.

Prior to that, Kozek was vice president and general manager of Paccar's Kenworth division, which included responsibility for all U.S. and Canadian operations. He held this role from October 2008 to June 2011.

He began his career as an accountant for Peterbilt in 1987, and served in a number of finance roles before moving into operations as a parts district manager for the Kenworth division in 1995. He spent the next 13 years at Kenworth moving through a number of key operational roles with increasing responsibility.
