ACL Toyota 6 5MGE/7MGE 0.25mm Oversized Main Bearing Set 1984-1998 - 7M1165A-.25

ACL 7M1165A-.25 Oversized Main Bearing Set

The ACL 7M1165A-.25 is a meticulously engineered main bearing set designed specifically for the Toyota 6 5MGE/7MGE engines manufactured between 1984 and 1998. This set features advanced metallurgy and precision manufacturing techniques that cater to high-performance applications, ensuring durability and reliability under demanding conditions.

Key Features

  • Trimetal Construction: The unique design integrates a high-strength overlay plate with reduced thickness, enhancing fatigue resistance and longevity in high RPM scenarios.
  • Hardened Steel Backing: Each bearing is equipped with hardened steel backs, providing superior support for the bearing lining and improving retention within the housing.
  • Increased Crush: Enhanced crush characteristics ensure better bearing retention, which is crucial for maintaining performance under load.
  • Optimized Heat Transfer: The elimination of flash plating on the backs of the bearings improves heat dissipation and maximizes the grip between the bearings and their housing.
  • Enhanced Eccentricity: Increased eccentricity compensates for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films for better lubrication.
  • 3/4 Grooved Design: This feature optimizes the load-carrying surface area and enhances oil flow to the connecting rod bearings, crucial for maintaining engine performance.
  • Tight Wall Tolerances: Consistent wall tolerances help maintain precise clearances, essential for engine efficiency and longevity.
  • Large ID Chamfers: Enlarged chamfers on the bearing edges accommodate larger fillet radii found on performance crankshafts, ensuring compatibility and performance.

Specifications

  • Large chamfer designed to fit larger crankshaft fillets.
  • 3/4 groove configuration for optimal oil delivery to connecting rods.
  • Increased crush and tighter wall tolerances for improved seating.
  • Enhanced overlay with reduced thickness for superior fatigue strength.
  • Hardened steel backing to maintain crush under high loads and temperatures.

The ACL 7M1165A-.25 main bearing set is engineered for those who demand the best from their Toyota engines. With its focus on high performance and reliability, this bearing set is an essential upgrade for any serious engine build.
