What does '.25mm undersize' mean for these bearings?

This means the inside diameter of the bearing is slightly smaller than a standard size bearing by 0.25mm. This is used when the crankshaft journals have been machined down (ground) to a smaller size, or if you are replacing existing undersize bearings. It ensures the correct clearance between the bearing and the crankshaft.

What material are these bearings made from?

These ACL bearings feature a tri-metal overlay. This construction is known for its strength and ability to withstand high loads and temperatures, making it suitable for performance V8 engines.

Do I need to buy anything else to install these bearings?

You will need engine assembly lube to properly coat the bearings before installation. It's also critical to ensure your crankshaft journals are clean and measured correctly to confirm the .25mm undersize is appropriate for your build. Always consult your vehicle's service manual for detailed installation procedures.

Product Details

Already running a built 5.7L Hemi? This connecting rod bearing set is the next piece of the puzzle for a strong bottom end. ACL is a well-known name in engine bearings, and this set is made to handle the demands of a performance V8. These bearings are .25mm undersize, which is crucial for ensuring proper clearance and oil film when working with a crankshaft that's been machined or is already running undersize bearings.

When you're building or rebuilding an engine, especially one like the 5.7L Hemi that can see a lot of use, the connecting rod bearings are critical. They sit between the crankshaft and the connecting rod, allowing the rod to spin freely while maintaining a thin film of oil for lubrication. This set from ACL uses a well-built tri-metal overlay material that's known for its strength and ability to handle high loads. Getting the right bearing clearance is key for engine longevity and performance, and these .25mm undersize bearings are designed to help you achieve that precise fit.

This set includes all the necessary connecting rod bearings for your 5.7L Hemi. Make sure to check your crankshaft's condition and measure its journals to confirm that a .25mm undersize bearing is the correct choice for your specific build. Always refer to the manufacturer's installation instructions for proper cleaning, lubrication, and assembly procedures.
