What does '.20mm Oversized' mean for these rod bearings?

This means the bearings are manufactured to be slightly larger than standard size. They are intended for use when the crankshaft's connecting rod journals have been machined down by 0.020 inches during an engine rebuild. This ensures the correct oil clearance is achieved after the machining process.

What is 'Trimetal' construction?

Trimetal bearings are made with a three-layer composite material. This construction typically includes a steel backing for strength, a copper-lead alloy for load carrying capacity, and a thin overlay of babbitt (a soft metal alloy) for excellent conformability and embeddability, helping to prevent foreign particles from causing damage.

Do these bearings come with installation instructions?

While these bearings are designed for a direct fit on compatible engines, specific installation procedures, including proper torque specifications and lubrication, should always be followed according to the vehicle's or engine manufacturer's service manual.

Product Details

Doing an engine rebuild on your classic Mopar V8? If you're working with a 318, 340, or 360 cubic inch engine from 1956 through 1998, these ACL trimetal rod bearings are a solid choice. They're designed to be installed when the crankshaft journals have been machined down by 0.020 inches, ensuring a proper fit and oil clearance after a rebuild. ACL has been making engine bearings for a long time, and their trimetal construction is well-known for handling the pressures and heat inside an engine.

These bearings use a multi-layer metal composite that's built to withstand high loads and provide good wear resistance. The trimetal design helps them conform to the crankshaft surface for optimal oil film support, which is crucial for preventing premature wear. Because these are oversized by 0.020 inches, they're specifically for engines where the connecting rod journals have been ground down to this size during the machining process of a rebuild. Make sure your machine shop has confirmed the correct journal size before ordering.

When you're putting an engine back together, getting the bearing clearances right is key to its longevity. These ACL bearings are a popular option for builders looking for reliable performance after a rebuild. Always refer to your specific engine's service manual for the correct installation procedures and torque specifications.
