What does '0.040 inch undersize' mean for these bearings?

This means the bearings are manufactured to be 0.040 inches smaller in diameter than standard. This is necessary when the crankshaft journals have been machined down (ground undersize) during an engine rebuild to remove wear or damage. You need to measure your crankshaft journals to ensure this is the correct size for your rebuild.

What other parts are typically needed when installing main bearings?

When replacing main bearings, it's common practice to also replace the connecting rod bearings (also known as rod bearings) at the same time. You will also need new engine oil and an oil filter for the initial fill after assembly.

Does this bearing set come with installation hardware?

This listing is for the crankshaft main bearing set only. It does not include any additional hardware or installation tools. Always refer to your vehicle's service manual for the correct installation procedure and any required specialized tools.

Product Details

ACL has been making engine bearings for decades, and this crankshaft main bearing set for your 1971-1974 Dodge Challenger is one of their staples. These bearings are a critical part of your engine's rotating assembly, supporting the crankshaft as it spins. When you're rebuilding your V8 360 engine, getting the right bearings is key to ensuring smooth operation and longevity.

This particular set is designed to be 0.040 inches undersize, which is important if your crankshaft journals have been machined down during a rebuild. ACL uses well-built materials to create bearings that can handle the pressures and heat inside your engine. They fit right into the factory locations, making installation straightforward for a mechanic or a dedicated DIYer.

When you're putting your engine back together, especially after it's been bored or had its crank ground, using the correct undersize bearings like these from ACL ensures a proper fit and oil clearance. Make sure to check your crankshaft journal measurements to confirm this 0.040 inch undersize is what you need for your specific rebuild.
