What is the advantage of extra oil clearance in these bearings?

Extra oil clearance allows for a larger volume of oil to flow through the bearing. This helps to keep the bearing surfaces cooler and ensures adequate lubrication, especially in high-performance or high-RPM applications where oil temperatures can rise significantly.

What does 'tri-metal construction' mean for these bearings?

Tri-metal bearings typically consist of three layers: a steel backing for strength, a middle layer of copper-lead alloy for load-carrying capacity, and a thin overlay of babbitt (a soft alloy) for conformability and embeddability. This combination offers a good balance of strength and durability for engine applications.

Do these bearings come with installation instructions?

While these bearings are designed as a direct replacement, it is always recommended to refer to the vehicle manufacturer's service manual for detailed installation procedures, torque specifications, and proper oil clearance measurements.

Product Details

When you're rebuilding or refreshing a Nissan VG30DETT engine, especially one that's going to see harder use, the main bearings are critical. These ACL high-performance main bearings are built with a special overlay that's designed to handle the increased loads and temperatures that come with performance applications. They also feature extra oil clearance, which is important for keeping things cool and well-lubricated when the engine is working hard.

ACL has been making engine bearings for a long time, and they know what it takes to build a solid part. These bearings use a tri-metal construction that offers good strength and wear resistance. The extra oil clearance they provide is a smart choice for engines that have been modified for more power or are expected to run at higher RPMs. This helps prevent oil starvation and reduces friction, which can extend the life of your engine components.

This set is for standard size mains and is a popular choice for VG30DETT builds where reliability and performance are key. Make sure to check your crankshaft journals for straightness and proper sizing before installation, and always follow the manufacturer's recommended torque and oil clearance specifications.
