ACL Race Main Bearings 7M7989-STD (93-98) Toyota Pickup 1FZ FE - Engine:ACL Bearing offers the unique combination of design, metallurgy and engineering come together to deliver what drivers expect from high performance Trimetal engine bearings. These Race Series Bearings are designed to withstand higher RPM conditions.

Features

• Improved Fatigue Properties due to a High Strength Overlay Plate with reduced thickness.
• 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.
