What does '0.75 Oversized' mean for these rod bearings?

This means the bearings are thicker than the standard size by 0.75mm. They are intended for use when the engine's crankshaft journals have been machined down by 0.75mm during an engine rebuild or repair.

Are these bearings sold individually or as a set?

This is a set of rod bearings. It includes all the necessary bearings to replace the rod bearings on your engine's crankshaft.

What is the main purpose of rod bearings in an engine?

Rod bearings are critical components that sit between the crankshaft and the connecting rods. They allow the crankshaft to rotate smoothly within the connecting rods while handling the significant forces generated during engine operation, ensuring proper lubrication and reducing friction.

About this part

Product Details

Doing an engine rebuild on your 2005-2008 Buick LaCrosse with the 3.2L or 3.6L HFV6? These ACL rod bearings are a crucial part of that job. Rod bearings sit between the crankshaft and the connecting rods, allowing them to spin smoothly while handling the immense forces from combustion. When you're rebuilding an engine, especially if the crankshaft has been machined, replacing these bearings with the correct size is essential for proper oil clearance and long-term engine health.

This set from ACL is specifically sized at 0.75mm oversized. This means they are designed to be used when the crankshaft journals have been ground down by 0.75mm, which is a common practice during engine machining to clean up wear or damage. ACL is known for making well-built engine bearings, and this set is no different. They are designed to provide the correct oil clearance needed for the HFV6 engine to run reliably after a rebuild.

When you're putting an engine back together, getting the bearing clearances right is key. Using the correct oversized bearings, like these 0.75mm ones from ACL, ensures that your freshly rebuilt LaCrosse engine will have the proper oil pressure and lubrication it needs to perform well and last.
