What does the +0.75mm size mean for these bearings?

The +0.75mm designation indicates that these bearings are undersize. They are intended for use when the crankshaft journals have been machined down by 0.75mm during an engine rebuild to correct wear or runout. Using the correct bearing size is crucial for proper oil clearance and engine health.

What is the construction of these connecting rod bearings?

These bearings are constructed with a bimetal design, featuring an aluminum base. This type of construction is chosen for its ability to handle heat and wear effectively, making it suitable for the demands of performance engines.

Are these bearings sold individually or as a set?

This product is a connecting rod bearing set, meaning it includes all the necessary bearings for a specific set of connecting rods on your engine. Typically, a set will contain enough bearings for all cylinders.

Product Details

These King Engine Bearings connecting rod bearings feature a bimetal construction with an aluminum base, a design choice that helps manage heat and wear in high-performance BMW engines. They are specifically sized at +0.75mm, meaning they are intended for crankshaft journals that have been machined down by that amount during an engine rebuild. This set is built to fit a wide range of BMW M30, M32, and B35 series engines found in models like the 535i, 635CSi, and 735i.

When you're rebuilding the bottom end of your engine, especially one with a performance heritage like these BMWs, the bearings are critical. King uses a bimetal structure that's well-suited for the demands placed on connecting rod bearings, offering a solid balance of strength and conformability. This particular set is 0.75mm undersize, which is important to note if your crankshaft has already been machined or if you are planning to have it machined to this specific size. Using the correct bearing size is essential for maintaining proper oil clearance, which is key to engine longevity and performance.
