ACL H Race Rod Bearing Each 0.25mm AUDI 2.5L TFSI 5 cyl. ACL 1B5562H-.25

One often overlooked part when building an engine is the bearings. Getting a quality set of bearings can directly determine the longevity of your engine. The -.25mm on the end of this part number means that the bearing is thicker than a standard bearing. These should be used when your crank has been cut .25mm (.010") under.

• 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.
• Tight consistent wall tolerances to help you maintain consistent clearances.
• Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts.
