ACL MAIN BRG SET - GM HFV6 Engine Crankshaft Main Bearing Set

You get a full set of main bearings in this kit, which means one box handles the whole engine bearing replacement. These ACL main bearings are made for the GM HFV6 engine found in your 2005-2008 Buick LaCrosse. When you're rebuilding or repairing your engine, the main bearings are critical. They sit between the crankshaft and the engine block, allowing the crankshaft to spin smoothly while supporting its weight and the forces from combustion.

This set is a 1.00 undersize bearing set, meaning it's designed to be used when the crankshaft has been machined down by 0.001 inches. This is a common practice during engine rebuilds to ensure a perfect fit and proper oil clearance on a crankshaft that's had some wear or has been resurfaced. ACL is known for making well-built engine components, and these bearings are no exception. They're designed to provide the correct oil clearance and support your engine needs.

When installing these bearings, make sure to follow the manufacturer's instructions carefully, especially regarding cleaning and lubrication. Proper oil clearance is key to engine longevity, so using the correct size bearings and ensuring the crankshaft is prepped properly is essential for a successful engine build.
