What is the difference between standard (STD) and undersize bearings?

Standard (STD) bearings are made to the original factory specifications. Undersize bearings, like -010 or -020, are used when the crankshaft journals have been machined down to remove damage or wear. Always match the bearing size to the crankshaft journal size.

What else might I need when installing connecting rod bearings?

When replacing connecting rod bearings, it's crucial to follow the manufacturer's installation instructions. This typically includes using a torque wrench to tighten the rod caps to the correct specification and ensuring proper lubrication of the bearings and crankshaft journals before assembly.

Are these bearings sold individually or as a set?

This is a set of connecting rod bearings. Typically, engine bearing sets are sold in sets of 4 or 8, depending on the engine's cylinder count, to ensure all rods are fitted with matching bearings.

Product Details

This set of ACL connecting rod bearings is built to meet the original specifications for your 2005-2009 Buick LaCrosse with the 3.8L V6 engine. Connecting rod bearings are critical for maintaining the correct oil clearance between the crankshaft and the connecting rod. This clearance is essential for proper lubrication and to prevent metal-on-metal contact, which can lead to serious engine damage. ACL has been a well-known name in engine bearings for a long time, and these are a solid option for a rebuild or repair.

This set replaces part number 6B1443A and is designed as a standard size (STD) replacement. When you're rebuilding an engine, getting the bearing clearances right is key to a long-lasting build. Make sure to follow the manufacturer's torque specifications and lubrication procedures during installation.
