King Engine Bearings Ford 232 (3.8L) (Size +0.50mm) Main Bearing Set

If you're rebuilding the engine in your 1989-1995 Ford Thunderbird, especially the 3.8L V6, new main bearings are a critical part of the job. These bearings sit between the crankshaft and the engine block, supporting the rotating assembly and ensuring smooth operation. This set from King Engine Bearings is specifically sized at +0.50mm, meaning it's intended for a crankshaft that has been machined down by that amount to correct wear or out-of-round conditions.

King Engine Bearings uses a bimetal construction with an aluminum silicon base. This material is chosen for its good load-carrying capacity and wear resistance, which is exactly what you need in a high-stress environment like the bottom end of an engine. Using the correct oversize bearing ensures a proper fit and oil clearance on a machined crankshaft, which is crucial for oil pressure and the longevity of your rebuild.

When installing these bearings, remember to always refer to the manufacturer's service manual for the correct torque specifications and procedures. Ensuring the crankshaft journals are clean and properly prepared is also key to a successful engine rebuild.
