What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are slightly larger than standard size. They are intended for use when the engine's crankshaft has been machined undersize by 0.25mm during a rebuild. This ensures the correct oil clearance is maintained.

What is the construction material of these bearings?

These bearings are made with a bimetal construction, featuring an aluminum silicon base. This material is chosen for its wear resistance and ability to handle engine loads.

Are these bearings a direct replacement for the original equipment?

These bearings are designed as a direct fit for the specified Toyota Land Cruiser and Lexus LX450 models. However, due to the +0.25mm sizing, they are intended for engines where the crankshaft has been machined to match this size.

About this part

Product Details

King Engine Bearings is well-known for making solid engine components, and this main bearing set is no exception. If you're rebuilding the bottom end of your 1993-1997 Toyota Land Cruiser or 1996-1997 Lexus LX450 with the 1FZFE engine, these bearings are designed to fit right in.

This set is built with a bimetal construction, using an aluminum silicon base. This type of material is chosen for its good wear characteristics and ability to handle the loads found in an engine's main bearing journals. These bearings are specifically sized at +0.25mm, which is important if you've had your crankshaft ground undersize during a rebuild. Using the correct undersize bearing ensures a proper oil clearance, which is critical for engine longevity.
