What is the main advantage of the silicon content in these bearings?

The higher silicon content, 60% more than many competitors, helps to condition the crankshaft journal surfaces. This leads to improved seizure and wear resistance, contributing to longer bearing life.

Are these bearings a direct replacement for all 1961-1981 GM V8 engines?

These bearings are designed for specific GM V8 engines within that range, primarily those with 265, 300, 301, 340, and 350 cubic inch displacements. Always verify fitment for your specific vehicle and engine combination.

What material are these Clevite bearings made from?

They are constructed from Clevite's BiMetal material, which is a 100% lead-free aluminum silicon alloy. This composition is chosen for its durability and performance characteristics in engine applications.

About this part

Product Details

If you're rebuilding a classic GM V8 engine from 1961 to 1981, these Clevite connecting rod bearings are a solid option. They're built for a range of popular displacement engines, including the 265, 300, 301, 340, and 350 cubic inch V8s found in vehicles like the Buick Skylark, Oldsmobile Cutlass, and Pontiac Firebird.

Clevite uses a BiMetal construction with 100% lead-free aluminum silicon. This material has 60% more silicon than many other bearings, which helps to condition the journal surfaces they run against. This improved surface conditioning leads to better resistance against seizing and wear, helping your engine last longer.
