What does 'STD Size' mean for these bearings?

STD size means the bearings are manufactured to the original equipment manufacturer's specifications. They are intended for use when the crankshaft journals are not worn beyond their factory tolerances and do not require machining.

What is the advantage of a bimetal bearing with an aluminum silicon base?

Bimetal bearings offer a good balance of strength and conformability. The aluminum silicon base provides good wear resistance and helps to maintain proper oil film thickness, which is essential for reducing friction and wear in the engine.

Do these bearings come with installation instructions?

While these bearings are designed as a direct replacement, it is always recommended to refer to the vehicle manufacturer's service manual for the correct installation procedures and torque specifications.

Product Details

Built with a bimetal construction featuring an aluminum silicon base, this crankshaft main bearing set is specifically made for the Toyota 1FZFE 4477CC engine. These bearings are crucial for maintaining proper oil clearance between the crankshaft and the engine block, ensuring smooth rotation and reducing friction during operation. When you're rebuilding the bottom end of your Land Cruiser or LX450, getting the bearing specs right is key to a long-lasting engine.
