What is the difference between standard size and undersize bearings?

Standard size bearings are meant to be installed on a crankshaft that is still at its original factory dimensions. Undersize bearings are used when a crankshaft has been machined down to correct for wear or damage.

Do these bearings come with assembly lube?

This set includes the rod bearings themselves. You will need to purchase a high-quality engine assembly lubricant separately to properly coat the bearings and crankshaft journals during installation.

What is the material of these rod bearings?

These ACL rod bearings feature a high-performance overlay material designed for durability and reduced friction, helping to protect your engine's rotating assembly.

Product Details

This ACL rod bearing set is built for the Nissan KA24DE engine, commonly found in models like the 240SX, Altima, and Frontier. Rod bearings are critical components that sit between the connecting rod and the crankshaft, allowing them to rotate smoothly while handling significant loads. Over time, these bearings can wear down, leading to increased friction, oil pressure loss, and potential engine damage. This set is designed as a standard size replacement, meaning it's meant to fit on a crankshaft that hasn't been machined undersize. ACL uses a high-performance overlay material that offers good durability and reduced friction, helping to maintain proper oil clearance and protect your engine's rotating assembly.

When you're rebuilding an engine or addressing bearing wear, using a well-built set like this from ACL is a solid choice. They are designed to handle the demands of daily driving and more spirited use. Make sure to follow proper installation procedures, including cleaning the crankshaft and connecting rods thoroughly and using the correct assembly lube, to ensure these bearings perform as intended.
