Product Description

The 6M1581H-STD main bearing set is intended for BMW’s high-revving S85B50 5.0L V10 engine used in the M5 and M6. These ACL Race bearing shells sit between the crankshaft journals and engine block, providing the controlled oil clearance required for the crankshaft to operate correctly. The STD specification makes this set suitable where the crankshaft remains within standard journal dimensions. A practical option for S85 engine rebuilds, bottom-end refurbishment and performance-focused overhaul work. Verify crankshaft measurements and required bearing specification before installation.
