ACL Race Main bearing shells suitable for BMW N54, N55 & S55 x35i/x40i

Racing bearing shells for all BMW N54, N55 and S55 engines Main bearings are subject to high wear and should be replaced regularly. Our bearings can withstand higher loads than normal series bearing shells.The bearing material is specially manufactured for higher loads and has a reinforced contact pressure.Thus, these bearings tend less to gefärlichen twisting in the bearing seat.The ovality of the bearing shells is increased to get better lubrication at higher speeds.Especially recommended for tuned engines with increased charge pressure.
