What is the purpose of connecting rod bearings?

Connecting rod bearings sit between the connecting rod and the crankshaft. Their main job is to reduce friction and wear, allowing the crankshaft to rotate smoothly within the connecting rod while handling the high forces generated during combustion.

What engine sizes does this bearing set fit?

This ACL bearing set is designed for several Buick V6 engine sizes, including the 181ci, 204ci (model years 1989-1990), 231ci (even fire type A, model years 1977-1988), 231 Turbo, and 252ci engines.

Do I need to replace these bearings during a standard tune-up?

Connecting rod bearings are typically replaced during a major engine overhaul or rebuild. They are not part of a routine tune-up, but if you are experiencing knocking noises or have significant engine wear, they may need replacement.

Product Details

You get a full set of connecting rod bearings in this kit, which means one box handles the whole engine rebuild or repair. These bearings are crucial for keeping your Buick Regal's V6 engine running smoothly. They sit between the connecting rod and the crankshaft, allowing the rotating assembly to spin freely while handling the immense forces involved. Without good bearings, you'll quickly run into serious engine damage.

This set from ACL is built for the Buick V6 engines found in your 1978-1987 Regal, covering the 181, 204, 231 (even fire), 231 Turbo, and 252ci displacements. They are .660 inches wide, which is the correct specification for these applications. ACL has been making engine bearings for a long time, and this set is a well-built option for anyone rebuilding or repairing their engine.

When you're putting an engine back together, getting the right bearings is key. Make sure you follow the manufacturer's instructions for installation, including proper lubrication and torque specifications for the connecting rod caps.
