Product Details

Built with a bimetal construction using an aluminum base, this King Engine Bearings main bearing set is designed for Toyota 2M, 4M, 5M, 5MGE, 7MGE, and 7MGTE engines. These bearings are specifically sized at +0.25mm undersize, making them suitable for engine rebuilding projects where the crankshaft journals have been machined to match this specification. They fit a range of popular Toyota models, including the Celica, Cressida, and Supra, offering a solid option for restoring your engine's bottom end.

The bimetal design with an aluminum base helps manage heat and provides a strong bearing surface for the crankshaft. This construction is a common choice for performance and durability in many engine applications. When rebuilding an engine, using bearings that are the correct size for the machined crankshaft journals is critical for proper oil clearance and long-term engine health. These King bearings are a well-made component for that purpose.
