What does 0.25mm oversized mean for these bearings?

This means the bearings are designed to fit crankshaft journals that have been machined down by 0.25mm. This is a common step when reconditioning a worn crankshaft to ensure proper oil clearance.

Are these bearings suitable for a stock engine rebuild?

These bearings are 0.25mm undersize, so they are intended for engines where the crankshaft has been machined to accept them. If your crankshaft is still at factory size, you would need a standard size bearing.

Product Details

ACL has been making engine bearings for decades, and this 0.25mm oversized rod bearing set for your Nissan is one of their staples. These bearings are designed for the QR25DE engine found in many popular Nissan models like the Altima, Sentra, Frontier, and Rogue. When rebuilding or refreshing an engine, especially one that's seen a lot of miles, replacing the connecting rod bearings is a critical step to ensure proper oil clearance and long-term health.

This set is 0.25mm oversized, meaning it's intended for crankshaft journals that have been machined down by 0.25mm. This is a common practice when a crankshaft has wear and needs to be reconditioned to factory specifications. ACL uses well-built materials and manufacturing processes to create bearings that meet or exceed OEM standards, providing reliable performance for your engine rebuild.

When you're working on your engine, make sure to have the correct specifications for your crankshaft journals. If you're unsure about the machining process or bearing selection, it's always best to consult with a professional engine builder.
