ACL Rod Bearing Set BMW F10 M5 V8 N63/S63

ACL Rod Bearing Set BMW F10 M5 V8 N63/S63 The BMW S63 engine comes from the factory with proper bearing clearance. This ACL rod bearing set is designed to replicate BMW standard rod bearing clearance. This bearing clearance is what we use on the race engines we build in the shop and what we recommend for this engine. Features: High strength overlay plate with reduced thickness for improved fatigue properties Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing. Increased crush for improved bearing retention Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing. Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films. 3/4 grooved Main Bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings.
