ACL Chevrolet V6 173-191-207 1985-04 Engine Crankshaft Main Bearing Set

Worn-out crankshaft main bearings can lead to excessive engine noise, oil pressure loss, and eventually, catastrophic engine failure. This ACL Main Bearing Set is built to replace the original bearings in your Chevrolet Celebrity, Lumina, or Monte Carlo, helping to restore proper engine function and longevity.

These bearings are made with a tri-metal construction, a popular choice for performance and durability. This material blend offers good embeddability and conformability, which helps them adapt to the crankshaft surface while providing solid wear resistance. The set includes bearings that are 0.010 inches undersize, meaning they are designed to be used with a crankshaft that has been machined down by 0.010 inches to ensure a precise fit and optimal oil clearance.

When you're rebuilding an engine or addressing bearing wear, using a well-built set like this ACL kit is important for ensuring your engine runs smoothly and reliably for miles to come. Always refer to your vehicle's service manual for proper installation procedures and torque specifications.
