ArvinMeritor has announced plans to spin off its car parts business from its larger trucking group in a move to improve the focus of each unit.

The truck business will continue to be called ArvinMeritor, while the car parts unit will be spun off under the name Arvin Innovation Inc.

The plan comes eight years after Arvin and Meritor merged to form an auto and truck parts supplier, according to a company press release.

ArvinMeritor hopes to complete the split within a year.

The heavy truck business has about 10,000 employees at 62 locations in 15 countries, producing axles and drivelines, brakes, suspensions and other parts for trucks, trailers, buses, military vehicles and off-highway vehicles.
