What does '.01mm undersize' mean for these bearings?

This means the bearings are manufactured to be 0.01 millimeters smaller in diameter than a standard, full-size bearing. They are intended for use with a crankshaft that has been machined down by 0.01mm during an engine rebuild.

What is trimetal construction?

Trimetal bearings typically consist of three layers: a steel backing for strength, a copper-lead alloy for load-carrying capacity, and a soft overlay (like babbitt) for conformability and embeddability. This construction is well-suited for the demands of performance engines.

Do these bearings come with installation instructions?

This set includes the rod bearings themselves. Always refer to the manufacturer's official installation instructions or a trusted service manual for proper installation procedures, torque specifications, and oil clearance checks.

Product Details

Already rebuilt the bottom end or looking to refresh your classic Ford V8? This ACL trimetal rod bearing set is designed to fit your 255, 289, or 302 cubic inch engine. These bearings are crucial for proper oil clearance between your connecting rods and crankshaft, ensuring smooth operation and longevity.

ACL uses a trimetal construction, which is known for its strength and ability to handle the pressures found in performance V8 engines. This set is precisely machined to be 0.01mm undersize, meaning they are intended for use with a crankshaft that has been machined down by that amount. This allows for a fresh, tight tolerance fit on a reground crankshaft, which is common in engine rebuilds.

When rebuilding or refreshing your engine, using the correct size bearings is key. These ACL bearings are a solid option for anyone looking to get their Ford V8 running right.
