What does 'extra clearance' mean for these bearings?

Extra clearance means these bearings have a slightly larger internal diameter than standard bearings. This allows for a thicker oil film, which is beneficial for engines under higher stress or those with slightly less-than-perfect crankshaft surfaces, helping to prevent metal-to-metal contact.

What is the benefit 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, good embeddability for small debris, and conformability to the crankshaft, making them well-suited for high-performance applications.

Are these bearings suitable for a daily driver or only for racing?

While designed for high performance, these bearings offer improved reliability and durability. They can be a good choice for a daily driver that sees occasional spirited driving or for a street-performance build where engine longevity is a priority.

Product Details

200,000 psi tensile strength puts these ACL rod bearings well above stock hardware. If you're rebuilding or tuning a Ford or Lotus 1500/1600 OHV or Twin Cam engine, these bearings are a solid choice for improved reliability under higher loads. They're designed with extra clearance, which is crucial when you're running tighter tolerances or expecting more stress on the rotating assembly.

ACL has been making engine bearings for a long time, and they know what it takes to handle the demands of performance builds. These bearings use a tri-metal construction, which is a popular choice for high-performance applications because it offers a good balance of strength, embeddability, and conformability. This means they can handle the heat and pressure while still conforming to the crankshaft surface for a solid oil film. The extra clearance built into this specific set helps ensure adequate oil flow, especially important if your crankshaft journals are not perfectly smooth or if you're using a high-volume oil pump.

This set includes bearings for standard size connecting rods. When you're putting an engine back together, especially one that's going to see spirited driving, using well-built bearings like these from ACL is a smart move to protect your investment and get the most out of your build.
