The five-year supply agreements are new business wins for ArvinMeritor's Commercial Vehicle Systems (CVS) business group.

Beginning Feb. 16, 2004, the Meritor Permalube RPL U-joint drivelines will be standard equipment on the Volvo VN linehaul tractors. The Permalube RPL includes a high-strength, compact design that eliminates periodic greasing requirements, which, in turn, provides cost savings to fleets. Plus, it includes a specially formulated wear- and temperature-resistant grease to keep bearings lubricated. The component will be assembled at the Manning, S.C., facility.

Effective March 1, 2004, Meritor RN U-joint drivelines will be standard equipment on all Mack tractors, with the RPL driveline to be offered as an option. The RN series, available for multiple applications, including linehaul, city delivery and construction vehicles, is designed to keep lubrication in and contaminants out, absorb metallic debris and accommodate varying yoke dimensions. The component will be assembled at ArvinMeritor's Manning, S.C., and St. Thomas, Ont., Canada, facilities.

"This significant new business for our company is further evidence of ArvinMeritor's growing global partnership with the Volvo Group, especially in the field of drivetrain products," said Brad Arnold, vice president and general manager, Commercial Vehicle Systems, Axles/Drivelines, ArvinMeritor. "Receiving this award demonstrates that they recognize our excellence in drivetrain-related technology and worldwide service support capabilities."
