Often called main bearings, crankshaft bearing shells sit between the rotating assembly and the engine block. They allow the crankshaft to rotate freely, but are prone to wear from deterioration and lack of lubrication.

This complete set consists of nine bearings, enough to fill each journal.

If you're overhauling your M10, choose Hella crankshaft-bearing shells for a lasting solution.
