What does '.01mm Oversized' mean for these rod bearings?

This means the inside diameter of these bearings is slightly larger than standard by 0.01 millimeters. This size is used when the crankshaft journals have been machined down by the same amount during an engine rebuild to ensure the correct bearing clearance.

What is trimetal construction?

Trimetal construction refers to a multi-layer bearing design. It typically includes a steel backing for strength, a copper-lead alloy for load carrying capacity, and a nickel barrier layer with a tin-aluminum overlay for wear resistance and compatibility with the crankshaft.

Do these bearings come with installation instructions?

While these bearings are designed as a direct replacement part, it is always recommended to consult your vehicle's specific service manual or a professional mechanic for detailed installation procedures and torque specifications.

Product Details

If you've rebuilt or are building a classic Chevy V8 with a 396, 402, 427, or 454 big block, these ACL trimetal rod bearings are a solid choice for ensuring proper clearances. These bearings are .01mm oversized, which is crucial when the crankshaft journals have been machined down during a rebuild to ensure they meet the correct specifications for optimal oil film and bearing life.

ACL has been making engine bearings for a long time, and their trimetal construction is well-known for its strength and durability. This design uses multiple layers of materials to handle the high loads and temperatures found in performance and heavy-duty applications. Using bearings that are precisely sized for your machined crankshaft is key to a healthy engine build, preventing premature wear and ensuring consistent oil pressure.

This set is specifically sized for crankshafts that have been turned down by .01mm. Always double-check your crankshaft journal measurements and consult your engine's service manual to confirm the correct bearing size needed for your specific build.
