What is the purpose of connecting rod bearings?

Connecting rod bearings are crucial components that sit between the connecting rod and the crankshaft. They allow the connecting rod to rotate smoothly around the crankshaft while handling high loads, preventing metal-on-metal contact and reducing friction.

When should I replace my connecting rod bearings?

It's highly recommended to replace connecting rod bearings during any engine rebuild or overhaul. They should also be considered if you're experiencing engine knocking noises, or if oil pressure issues arise, as worn bearings are a common cause.

What is the significance of the .660" width?

The .660 inch width refers to the surface area of the bearing that contacts the crankshaft journal. This specific width is designed to match the factory specifications for the Buick V6 engines listed, ensuring proper load distribution and oil film support.

Product Details

Already running a rebuilt or performance V6 engine in your 1978-1987 Buick Regal? This set of connecting rod bearings from ACL is the next piece of the puzzle for ensuring smooth operation and longevity. These bearings sit between your connecting rods and crankshaft, handling the immense forces generated during combustion and rotation. Getting them right is critical for engine health, especially when you're pushing your V6 beyond stock specifications.

ACL has been making engine bearings for a long time, and this set is built to handle the demands of the Buick 181, 204, 231 (even fire), 231 Turbo, and 252 cubic inch V6 engines. They're .660 inches wide, designed to fit precisely where the factory ones go. When you're rebuilding an engine, especially one that's seen a few miles or is being modified, replacing these bearings is a non-negotiable step to prevent premature wear and potential catastrophic failure.

This set is specifically for the 4.1L (252ci) V6 engine found in your Regal, and it's a direct replacement for the original equipment. Make sure you have the correct torque specifications and assembly lube before you begin installation, as proper setup is key to getting the most out of these well-built bearings.
