Bearings Specification, Dimensions, Clearance

OEM 088/089 Bearings

Production and Composition

BMW "088/089" bearings were the factory production bearings between 2007 to mid-2010. When the EU mandated the removal from lead in automotive bearings, BMW discontinued these bearings.
The composition is a standard babbit lead/copper bearing. They are soft faced, and easy on the crankshaft.
