What does 'Standard Size' mean for these bearings?

Standard size bearings are designed to fit crankshaft journals that are still within the original factory specifications. If your crankshaft has been previously ground undersize due to wear or damage, you would need a different size bearing set.

What is the advantage of a bimetal bearing with an aluminum base?

Bimetal bearings, especially those with an aluminum base, offer good strength and conformability. This construction helps them manage heat effectively and resist wear, while also allowing them to conform slightly to the crankshaft journal for optimal oil film formation.

Do these bearings come with installation instructions?

While these bearings are designed as direct replacements, it is always recommended to consult your vehicle's specific service manual for detailed installation procedures, torque specifications, and any special assembly requirements.

About this part

Product Details

These King Engine Bearings main bearing set uses a bimetal construction with an aluminum base, a design choice that helps manage heat and wear in NISSAN L20B, Z20, Z22, and Z24 engines. This set is designed as a standard size replacement, meaning it's intended to fit engines where the crankshaft journals are still within their original factory specifications. If you're rebuilding one of these NISSAN engines, whether it's for a 200SX, a D21 pickup, or a Pathfinder from the 80s, getting the right bearings is crucial for oil pressure and the longevity of your crankshaft.

King Engine Bearings is a well-known name in engine components, and this set reflects their focus on providing reliable parts. The bimetal construction is a common and effective approach for main bearings, offering a good balance of strength and conformability to the crankshaft journal. This helps ensure proper oil film thickness, which is essential for preventing metal-to-metal contact and reducing friction during operation. When installing, always ensure the crankshaft journals are clean and within spec, and refer to your engine's service manual for proper torque and assembly procedures.
