Product Details

You get a full set of main bearings in this kit, which means one box handles the critical bottom-end rotating assembly for your engine rebuild. These ACL bearings are built to replace the original equipment, ensuring proper oil clearance and support for your crankshaft. They're a solid option when you're putting a 3800 Series II V6 back together, whether it's for a Buick LeSabre, Park Avenue, Regal, or even a Chevrolet Camaro or Pontiac Firebird from the mid-90s to the mid-2000s.

ACL has been making engine bearings for a long time, and these are well-built for the job. They use a tri-metal construction that's designed to handle the pressures and temperatures inside your engine. This means they'll help maintain consistent oil pressure and reduce friction, which is key for engine longevity. When you're installing these, make sure to follow the manufacturer's torque specifications and use the correct assembly lube to get the best performance and life out of them.

This set is specifically for the standard size crankshaft journal. If your crankshaft has been machined undersize due to wear or damage, you'll need a different bearing size. Always double-check your crankshaft dimensions before ordering to ensure you get the right fitment for your rebuild.
