ACL 68-89 Nissan 1952cc/2187cc/2389cc 4cyl Standard Size High Performance Rod Bearing Set

200,000 psi tensile strength puts these ACL rod bearings well above stock hardware. If you're rebuilding an engine for a 1968-1989 Nissan with a 1952cc, 2187cc, or 2389cc 4-cylinder engine, these are a solid choice for improved durability. They're made with a tri-metal overlay that's designed to handle higher loads and temperatures than standard bearings, which is crucial when you're pushing an engine harder or dealing with increased performance. ACL has been making bearings for a long time, and they know how to build them to last.

These are standard size bearings, meaning they're meant to be used with a crankshaft that's still within its original specifications. If your crankshaft has been machined undersize due to wear or damage, you'd need a different size bearing. The tri-metal construction is key here; it offers a good balance of strength, conformability to the crankshaft journal, and embeddability for small debris, all while maintaining a strong oil film. This helps protect your engine's rotating assembly under stress.

When you're putting an engine back together, especially one that's going to see more than just daily driving, using good bearings is essential. These ACL bearings are a popular option for many Nissan builds because they offer a noticeable step up in performance and reliability without breaking the bank. Just be sure to follow proper installation procedures, including checking bearing clearances with Plastigage and ensuring your crankshaft journals are clean and smooth.
