About this part

Product Details

If you're rebuilding the bottom end of a classic GM V8 engine from 1961 to 1981, these Clevite connecting rod bearings are a solid option. They're built for engines like the 265, 300, 350, and others, covering a wide range of popular GM passenger cars and trucks from that era. These bearings are crucial for ensuring smooth rotation of your crankshaft and proper oil flow within the engine.

Clevite uses a BiMetal aluminum silicon alloy for these bearings, which is 100% lead-free. What's notable is that they contain 60% more silicon than many other bearings out there. This extra silicon helps to condition the journal surfaces they run against, leading to better resistance against seizing and wear. This means you can expect a more durable rebuild that holds up over time.

This set is designed to fit right into a variety of GM vehicles, including models like the Buick Skylark, Oldsmobile Delta 88, and Pontiac Firebird from the specified years. Make sure to check the full fitment list to confirm compatibility with your specific application.
