What is the main benefit of the higher silicon content in these bearings?

The higher silicon content, 60% more than comparable replacements, helps to condition the journal surfaces. This leads to improved resistance against seizing and wear, contributing to a longer lifespan for your engine's connecting rod journals.

Are these bearings a direct replacement for the original equipment?

Yes, these Clevite bearings are designed as a direct replacement for the original equipment on the specified Toyota 1.5L 1NZFE/1NZFXE engines and compatible Chevrolet and Pontiac models. They are intended to fit and function like the factory bearings.

What does 'CB1863A50MM(4)' signify in the part number?

The 'CB' typically indicates Clevite Bearings. The '1863A' is the specific bearing design number, and '50MM' refers to the main journal diameter in millimeters. The '(4)' often denotes that this is a set for a 4-cylinder engine, with each bearing being a specific size.

About this part

Product Details

If you're rebuilding the bottom end of a Toyota 1.5L 1NZFE or 1NZFXE engine, or a compatible Chevrolet Prizm, Pontiac Vibe, or Toyota MR2 Spyder, this Clevite connecting rod bearing set is a solid option. These bearings are built to handle the demands of daily driving and more, carrying on Clevite's tradition of durability.

What sets these bearings apart is their construction. They use a bi-metal aluminum silicon material that contains 60% more silicon than many other bearings you might find. This higher silicon content helps to condition the journal surfaces they run against, which in turn offers better resistance to seizing and wear. This means your engine's connecting rod journals will stay smoother for longer, contributing to overall engine longevity.

This set is designed to fit a range of vehicles, including popular models like the Toyota Corolla and Matrix. When you're putting an engine back together, using well-built bearings like these is key to a reliable rebuild.
