ACL Buick V6 204-231 1990-93 Engine Crankshaft Main Bearing Set

Rebuilding the top end of your Buick, Oldsmobile, or Pontiac 3800 V6 engine? These ACL Engine Crankshaft Main Bearing Sets are a crucial part of that process. They sit between the crankshaft and the engine block, allowing the crank to spin smoothly while handling the immense forces generated during combustion. Getting these right is key to a long-lasting engine rebuild.

ACL has been making engine bearings for a long time, and this set is built to handle the demands of your V6. They're made with a specific material composition designed for durability and low friction, which is exactly what you need when you're putting a freshly rebuilt engine back together. This set is a 0.010 inch undersize bearing set, so make sure your crankshaft has been machined to match this size before installation.

When you're doing an engine rebuild, it's important to have all the right parts. This bearing set is designed to fit specific 3800 V6 engines from the early 90s. Always double-check the fitment details to make sure it's the right set for your specific engine code and year.
