What does the +.25mm sizing mean for these bearings?

The +.25mm sizing indicates that these bearings are intended for crankshaft journals that have been machined down by 0.25mm. This is a common step during engine rebuilding to correct wear on the connecting rod journals.

What is the advantage of the tri-metal copper-based material?

The tri-metal copper-based material offers excellent strength and load-carrying capacity. Combined with the enhanced babbitt overlay, it helps provide a durable and reliable bearing surface for the crankshaft.

Are these bearings suitable for heavy towing applications?

These bearings are described as ideal for medium-load engines. For heavy towing or high-performance applications, it's always best to consult with a professional engine builder to ensure the correct bearing specification for your specific use.

About this part

Product Details

Built with a tri-metal copper-based material and an enhanced babbitt overlay, this King Engine Bearings connecting rod bearing set is a solid option for medium-load engines. Specifically, this set is sized at +.25mm, meaning it's designed to fit crankshaft journals that have been machined down by that amount during an engine rebuild. This is a common practice when addressing wear on the connecting rod journals.

King Engine Bearings has been specializing in bearing technology since 1960, focusing on supplying high-quality components. This set is engineered for GM Duramax 6.6L diesel engines, covering a range of model years and vehicles like the Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD. If you're rebuilding the bottom end of your Duramax, these bearings are designed to handle the demands of that engine.
