What does the .025mm oversize mean for my engine rebuild?

This means the bearings are slightly larger than standard. They are used when the crankshaft journals have been machined down (ground undersize) during a rebuild to ensure proper clearance and oil film.

What is the construction of these ACL rod bearings?

These bearings feature a tri-metal construction. This type of bearing material is known for offering a good balance of strength, conformability, and wear resistance, making it suitable for performance applications.

Are these bearings sold as a set for all connecting rods?

Yes, this is a set of high-performance connecting rod bearings designed for the KA24DE engine. It includes the necessary bearings to replace all connecting rod bearings in the engine.

Product Details

Rebuilding the top end of your Nissan KA24DE engine? If you're looking for a solid set of connecting rod bearings, ACL has you covered. These are designed for the KA24DE 2389cc inline 4-cylinder engine found in popular models like the 240SX, Altima, Frontier, and Xterra. When you're putting an engine back together, especially if it's been modified or is seeing higher mileage, fresh bearings are a critical part of the job.

This set is .025mm oversized, which is important if your crankshaft journals have been ground undersize during a rebuild. ACL is well-known for making durable engine bearings, and this high-performance set uses a tri-metal construction that offers good strength and wear resistance. They're built to handle the demands of a performance engine, providing a reliable interface between the connecting rod and the crankshaft.

When installing these bearings, make sure to follow the manufacturer's lubrication and clearance specifications carefully. Cleanliness is also key during engine assembly to ensure these bearings perform as intended for a long time.
