What does '0.025 inch undersize' mean for these bearings?

This means the bearings are slightly smaller than standard size. They are intended for use when the engine's crankshaft journals have been machined down by 0.025 inches to restore proper oil clearance and fit.

What is the advantage of the tri-metal construction?

Tri-metal bearings use three layers of material, typically a steel backing, a copper-lead alloy, and a softer overlay like babbitt. This combination offers a strong foundation with excellent conformability and embeddability, allowing them to handle high loads and pressures effectively.

Are these bearings suitable for a stock engine rebuild?

While these are Race Series bearings built for performance, they can be used in a stock rebuild if the crankshaft has been machined to the 0.025 inch undersize specification. For a standard rebuild without machining, you would typically need a standard-size bearing set.

About this part

Product Details

ACL has been making engine bearings for decades, and this Race Series connecting rod bearing set for your 2.4L SRT-4 is one of their staples. These bearings are built for demanding use, helping to keep your engine running smoothly under stress. They are a popular choice when rebuilding or upgrading engines, especially those that see track time or are pushed hard.

This set is a 0.025 inch undersize, meaning it's intended for crankshafts that have been machined down by that amount to restore proper clearances. The Race Series bearings feature a tri-metal construction, which is well-known for its strength and ability to handle high loads. They also have a higher performance overlay to help them withstand the increased heat and friction found in performance applications. ACL uses a special hardening process for these bearings to improve their durability.

When you're rebuilding an engine, getting the bearing clearances just right is critical for longevity and performance. If you've already had your crankshaft measured and machined to a 0.025 inch undersize, this set is what you'll need to put it all back together correctly. Make sure to follow the manufacturer's installation instructions carefully, as proper lubrication during installation is key.
