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

The 60% higher silicon content helps to better condition the crankshaft journal surfaces. This leads to improved resistance against seizing and wear, contributing to a longer engine life.

Are these bearings a direct replacement for the original equipment?

Yes, these Clevite connecting rod bearings are designed as direct replacements for the specified GM engines. They are intended to fit right into your engine rebuild without modification.

What does 'BiMetal' refer to in the product description?

BiMetal refers to the construction of the bearing, which typically consists of a steel backing for strength and a bearing material overlay, in this case, an aluminum silicon alloy, for the actual running surface.

Product Details

If you're rebuilding the engine in your classic GM passenger car or truck, getting the right connecting rod bearings is crucial for a long-lasting rebuild. These Clevite BiMetal bearings are made with a lead-free aluminum silicon alloy that's well-built for durability. They carry on Clevite's tradition of dependability for your engine project.

What sets these bearings apart is their composition: they contain 60% more silicon than many other bearings you might find. This higher silicon content helps condition the journal surfaces they run on, leading to better resistance against seizing and wear. This means your engine can run smoother and last longer, especially important when you're putting in the work for a full engine overhaul.

These bearings are designed to fit a range of GM vehicles from the 1960s through the late 1970s, including popular models like the Buick Skylark, Oldsmobile Cutlass, and Pontiac Firebird. Make sure to check the fitment details to confirm they're the right match for your specific application.
