What does '.025 oversized' mean for these rod bearings?

'.025 oversized' means these bearings are slightly thicker than standard bearings. They are used when the crankshaft journals have been machined down by 0.025 inches during an engine rebuild to ensure the correct oil clearance is maintained.

What is the advantage of tri-metal construction?

Tri-metal bearings use three layers of material, typically a steel backing, a bronze-nickel intermediate layer, and a lead-tin-copper overlay. This construction offers excellent strength, embeddability, and conformability, making them ideal for high-load and high-performance applications.

Are these bearings suitable for a stock engine rebuild?

While these are high-performance bearings, they can be used in a stock engine rebuild if the crankshaft journals have been machined down. However, they are primarily designed for engines that experience higher stresses than a typical stock application.

Product Details

200,000 psi tensile strength puts these ACL rod bearings well above stock hardware. If you're building a high-performance MZR Duratec 2260cc turbo engine, you need bearings that can handle the extra stress. These bearings are specifically designed for those applications, offering a solid option for engine rebuilds where reliability is key. They are manufactured with a tri-metal material that's known for its strength and ability to withstand high loads.

This set is .025 oversized, which is important if your crankshaft journals have been machined down during a rebuild. Using the correct oversized bearing ensures a proper oil clearance, which is critical for engine longevity and performance. The tri-metal construction provides excellent embeddability and conformability, meaning the bearing can adapt to slight imperfections in the crankshaft while maintaining a strong oil film. This helps reduce friction and wear, even under extreme conditions.

When rebuilding a performance engine, attention to detail is everything. These ACL bearings are a well-built component that can make a significant difference in the overall health and performance of your MZR Duratec turbo build. Always refer to your engine's service manual for proper installation procedures and torque specifications.
