What does the +1.0mm sizing mean for these bearings?

The +1.0mm sizing means these bearings are designed for a crankshaft that has been machined down by 1.0mm. This is typically done during an engine rebuild to correct wear or damage on the crankshaft journals.

What is the benefit of the bimetal aluminum base construction?

The bimetal construction with an aluminum base offers a good balance of strength and conformability. This helps the bearing withstand engine loads and heat while maintaining proper oil clearance.

Are these bearings suitable for a stock engine rebuild?

Yes, these bearings are suitable for stock engine rebuilds, especially if the crankshaft journals require machining to a +1.0mm undersize. They are designed to provide reliable support for the crankshaft.

About this part

Product Details

These main bearings are built with a bimetal construction, featuring an aluminum base. This design is crucial for handling the loads and heat generated within your Renault's engine. If you're rebuilding the bottom end of your 1983-1987 Renault Alliance, or Encore and LeCar models from the specified years, these bearings are a solid choice for ensuring proper crankshaft support.

The +1.0mm sizing indicates these bearings are intended for use when the crankshaft journals have been machined down by 1.0mm. This is a common practice during engine overhauls to clean up worn or damaged surfaces, and using the correct undersize bearing ensures a precise fit and optimal oil clearance. King Engine Bearings is a well-known name in the performance and racing world, and their attention to material science helps create durable components for your engine.
