What does '.10mm oversized' mean for these bearings?

This means the bearings are slightly larger in diameter than standard size. They are intended for use when the crankshaft's connecting rod journals have been machined down by 0.10mm to correct wear or out-of-round conditions. This ensures proper oil clearance and a snug fit on the crankshaft.

What is trimetal construction?

Trimetal bearings feature a multi-layered construction, typically consisting of a steel backing for strength, a middle layer of bearing alloy (like copper-lead), and a thin overlay of a softer material (like babbitt). This design offers good load-carrying capacity and wear resistance.

Do these bearings come with installation instructions?

While specific installation instructions are not included with the product, it is crucial to refer to the manufacturer's service manual or a trusted automotive repair guide for proper installation procedures, torque specifications, and oil clearance measurements.

Product Details

Doing an engine rebuild on your classic Chevy V8, likely a 396, 402, 427, or 454 big block? These ACL trimetal rod bearings are a solid option for getting your engine back in shape. They're designed to handle the demands of these larger displacement engines, especially if you're looking to restore or rebuild after significant mileage.

ACL has been making engine bearings for a long time, and these are built with a trimetal construction. This means they have multiple layers of material, which helps them handle load and wear well. Since these are .10mm oversized, they're meant to be used when the crankshaft journals have been machined down to compensate for wear. This is a common step in a performance or rebuild application to ensure a proper fit and oil clearance.

When you're putting these in, make sure to follow the manufacturer's instructions for installation and torque specifications. Proper oil clearance and lubrication are key to making sure these bearings last. If you've already had your crankshaft journals measured and machined to the correct undersize, these bearings will fit right in.
