What does 'undersize 0.50mm' mean for these bearings?

An undersize bearing means it's slightly larger in diameter than a standard bearing. This set is 0.50mm larger, which is used when the crankshaft journals have been machined down to correct for wear or damage. It allows you to achieve the correct oil clearance even after machining.

Why are crankshaft main bearings important?

Crankshaft main bearings support the crankshaft within the engine block. They create a precise gap for oil to flow through, lubricating the surfaces and reducing friction and wear. Proper function is crucial for engine longevity and performance.

Do these bearings come with new seals or gaskets?

This listing is for the crankshaft main bearing set only. Seals, gaskets, and other related engine components are typically sold separately and should be checked for replacement during an engine rebuild.

About this part

Product Details

When you're rebuilding an engine or just replacing worn parts on your 2014-2019 Jeep Grand Cherokee, the crankshaft main bearings are critical. These ACL bearings are built to handle the loads and heat generated by the engine's rotating assembly. They are designed to provide a precise oil clearance between the crankshaft and the engine block, which is essential for proper lubrication and preventing premature wear.

This particular set is an undersize bearing, meaning it's 0.50mm larger in diameter than a standard bearing. This is useful when the crankshaft journals have been machined down to correct for wear or damage. Using the correct undersize bearing ensures you can still achieve the proper oil clearance, even after machining. ACL is known for making well-built engine components, and these bearings are no exception, offering a solid option for your engine build.
