What does the +0.50mm size mean for these bearings?

The +0.50mm designation indicates that these bearings are 0.50mm undersize. They are intended for use when the engine's crankshaft has been machined down by 0.50mm to remove wear or imperfections. Always confirm your crankshaft's machined size before ordering bearings.

What is the material of these main bearings?

These bearings are made with a bimetal construction, featuring an aluminum silicon base. This material is chosen for its ability to handle the loads and heat generated by the rotating crankshaft.

Do these bearings come with new hardware?

This listing is for the main bearing set only. Hardware such as main cap bolts or crankshaft thrust washers are typically sold separately and should be replaced with new, high-strength fasteners during an engine rebuild.

About this part

Product Details

If you're rebuilding the bottom end of your 1993-1997 Toyota Land Cruiser or 1996-1997 Lexus LX450 with the 1FZFE engine, a fresh set of main bearings is crucial. These bearings sit between the crankshaft and the engine block, supporting the rotating assembly and handling significant loads. This set is specifically sized at +0.50mm, meaning it's intended for a crankshaft that has been machined down by 0.50mm to clean up wear or damage.

King Engine Bearings uses a bimetal construction with an aluminum silicon base for these main bearings. This material choice helps manage heat and wear effectively, providing a solid foundation for your engine's rotating assembly. Because these are an undersize bearing, they are designed to be used only after the crankshaft has been professionally machined to the correct undersize specification.
