What is the difference between standard and undersize bearings?

Standard size bearings are meant for a crankshaft that is still at its original factory diameter. Undersize bearings are used when a crankshaft has been machined down to correct for wear or damage, and they are sized to match the new, smaller diameter of the journals.

Do these bearings come with new seals or gaskets?

This listing is for the crankshaft main bearing set only. Seals and gaskets are typically sold separately, and it's recommended to replace them when performing an engine rebuild.

What is the tensile strength of these bearings?

The ACL 5M1344A-STD main bearings are constructed with materials that offer a tensile strength of 200,000 psi, which is significantly higher than typical stock hardware.

About this part

Product Details

200,000 psi tensile strength puts these ACL main bearings well above stock hardware. When you're rebuilding or refreshing a Chrysler Production V8 engine, especially the 318 cubic inch displacement, using a solid set of main bearings is crucial for engine longevity. These bearings are designed to handle the stresses of daily driving and more demanding use, ensuring your crankshaft spins smoothly within the engine block.

ACL has been making engine bearings for a long time, and this set is built to meet the needs of your engine. They're made with a multi-layer material that balances strength and the ability to conform to the crankshaft journal for optimal oil film retention. This means less friction and wear, which is exactly what you want when you're putting an engine back together. They are a standard size, meaning they're intended for use with an undamaged, factory-spec crankshaft. If your crankshaft has been machined, you'll need to check for undersize bearings.

This set is designed to fit a wide range of Chrysler Production V8 engines from 1974 through 1998, covering popular models like the Dodge Charger, Dakota, Ram 1500, and Plymouth Fury. Make sure to verify fitment for your specific vehicle year and model.
