What does a main bearing do?

Main bearings sit between the crankshaft and the engine block. They support the crankshaft, allowing it to spin smoothly while reducing friction and wear. Proper main bearings are essential for engine health and longevity.

What is the tri-metal construction?

Tri-metal construction refers to a bearing material made of three layers. This design typically includes a steel backing for strength, a middle layer for embeddability and strength, and a bearing surface layer that handles direct contact with the crankshaft journal.

Do I need to replace my crankshaft when installing these bearings?

These bearings are designed to fit the factory crankshaft journals. However, it's always recommended to inspect your crankshaft for any damage, wear, or out-of-roundness before installing new bearings. If the journals are damaged, the crankshaft may need to be machined or replaced.

Product Details

The MS2014H main bearing set from Clevite is built with a tri-metal construction, a popular choice for its durability and ability to handle the loads inside your engine. These bearings are crucial for supporting the crankshaft, allowing it to spin smoothly within the engine block. If you're rebuilding the bottom end of your 1993-2005 Lexus GS300, or any of the other compatible Toyota and Lexus models, getting the right main bearings is a key step to ensuring the health and longevity of your engine.

Clevite uses a tri-metal material that offers a good balance of strength and conformability, which helps these bearings adapt to minor imperfections in the crankshaft journal while still providing solid support. This means they can handle the pressures and heat generated during operation, helping to prevent premature wear. This set is designed as a direct replacement, meaning it fits right into the factory location without needing modifications, making your engine rebuild process smoother.

When you're putting an engine back together, especially after a rebuild or if you're addressing oil pressure issues, using well-made bearings like these from Clevite is important. They are a solid option for many Toyota and Lexus applications from the early 90s through the mid-2000s, covering models like the GS300, IS300, SC300, Supra, and Tacoma.
