BMW 550i F10/F11 408HP N63B44A 2010-2013

The 408hp 550i F10 and F11, built from 2010 to 2013, carries the 4.4 32V twin-turbo V8 N63B44A. On this block the big end changes part way through its life.

That is what governs this page: we stock two distinct tri-metal big end bearing sets, one from KING RACING for engines up to 2011, shared with the N62B40 and N62B48, and one from ACL RACE and KING RACING from 2011 onwards. Check the build year before ordering. Alongside them come the tri-metal main bearings and the ATHENA or COMETIC uprated head gasket, sold individually.
