ACL Race Series Engine Bearings - 7M8103A-STD

When it comes to maximizing performance in your Lexus GS300 (1993-2006), SC300 (1992-2000), or Toyota Supra (1986-2002), the ACL Race Series Engine Bearings 7M8103A-STD are engineered to meet the demands of high RPM driving. These bearings are a critical component for those pushing their engines to the limit, offering a unique blend of design and metallurgy that ensures reliability and durability under extreme conditions.

Key Features

• High strength overlay plate with reduced thickness enhances fatigue properties, allowing for better performance at high RPMs.
• Hardened steel backs on all rod bearings provide superior support for the bearing lining, ensuring solid retention within the housing.
• Increased crush improves bearing retention, keeping everything in place during aggressive driving.
• Removal of flash plating on the back of the bearings optimizes heat transfer, maximizing grip between the bearings and their housing.
• Enhanced eccentricity compensates for bore distortion at high RPMs, facilitating the formation of hydrodynamic oil films for better lubrication.
• 3/4 grooved main bearings optimize the load-carrying surface area and oil flow to the conrod bearings, crucial for performance applications.
• Tight, consistent wall tolerances help maintain precise clearances, essential for high-performance builds.
• Enlarged ID chamfers accommodate large fillet radii on performance crankshafts, ensuring a perfect fit.
