What does the 'STDX' size mean for these bearings?

The 'STDX' designation indicates that these bearings are 0.040 inches undersize compared to the standard size. This is typically used when the crankshaft journals have been machined down to this specific undersize during an engine rebuild or reconditioning process.

Are these bearings sold individually or as a set?

This product is a set of connecting rod bearings. You will receive multiple bearings, enough to service all the connecting rods in your specified BMW engine.

What is the primary function of connecting rod bearings?

Connecting rod bearings are essential components that sit between the connecting rod and the crankshaft. Their main job is to reduce friction and wear by allowing the crankshaft to rotate smoothly within the connecting rod while handling the high loads generated during engine operation.
