ACL RACE conrod bearings Race for BMW M40/M42/M43/M44 (6 pairs)

The pack contains 6 pairs – each pair is the upper and lower shell of one journal. Conrod bearings carry the load of the piston and rod on the crank pin, so their material and precision matter most in high-output engines.

ACL Race Series bearings are designed for sustained high-rpm loads in uprated engines and for the demands of race engines.
