What does '0.026 inch undersize' mean for these bearings?

This means the bearings are manufactured to be 0.026 inches smaller in diameter than standard size. This is necessary when the crankshaft journals have been machined undersize during an engine rebuild to correct wear or damage.

What is the material construction of these bearings?

These bearings feature King's XP series tri-metal construction. This design includes a unique overlay material that is known for its strength, durability, and ability to absorb shock loads while reducing friction.

Are these bearings suitable for stock or modified engines?

These bearings are designed for high-performance BMW S65B40A and S85B50A engines. Their robust construction and specific sizing make them a solid option for both rebuilt stock engines and modified applications where increased durability is needed.

About this part

Product Details

These King Engine Bearings are built with a unique overlay material that offers improved strength and durability, especially important for high-performance BMW S65B40A and S85B50A engines. This particular set is machined to be 0.026 inches undersize, which is critical when rebuilding or reconditioning an engine that may have had its crankshaft journals ground down. Using the correct undersize bearing ensures proper oil clearance, which is vital for oil pressure and bearing longevity.

King uses a specialized tri-metal design in their XP series bearings. This construction helps to absorb shock loads and reduce friction, contributing to a longer lifespan for both the bearings and the engine. The precision machining means they fit right into place, making installation straightforward for a mechanic familiar with engine builds.
