What does 'extra oil clearance' mean for these bearings?

Extra oil clearance means there is a slightly larger gap between the bearing and the crankshaft journal. This allows for a more consistent flow of oil, which is beneficial for engine cooling and lubrication, especially under demanding conditions.

Are these bearings suitable for a stock EcoBoost 3.5L engine rebuild?

Yes, these are standard size bearings designed for engines with crankshaft journals still within factory specifications. They are a well-built replacement option for stock EcoBoost 3.5L V6 engines.

What is the tri-metal overlay material used in these bearings?

The tri-metal overlay is a common material in high-performance bearings, consisting of three layers. It offers excellent strength, conformability to embed debris, and good wear resistance, contributing to the bearing's overall durability.

Product Details

ACL's 6B4380HX-STD connecting rod bearing set is built for Ford's EcoBoost 3.5L V6 engines. These bearings are a critical component for engine health, providing a smooth, low-friction surface between the connecting rod and the crankshaft. If you're rebuilding an EcoBoost engine or addressing bearing wear, this set offers a solid option for reliable performance.

What sets these bearings apart is their design for extra oil clearance. This means there's a slightly larger gap between the bearing and the crankshaft journal, allowing for a more consistent flow of oil. This is particularly beneficial in high-performance or heavily worked engines where oil pressure can fluctuate, helping to prevent metal-on-metal contact and reduce wear. ACL uses a tri-metal overlay on these bearings, which is a well-known material for its strength and ability to embed debris, offering improved durability over standard bearings.

This set includes standard size bearings, meaning they are designed to fit crankshaft journals that are still within their original factory specifications. If your crankshaft has been machined undersize due to wear or damage, you would need a different size bearing. Always ensure your crankshaft journals are clean and measured correctly before installation. Refer to the manufacturer's installation instructions for proper torque specifications and assembly procedures.
