What does '0.50mm oversized' mean for these rod bearings?

This means the bearings are manufactured to be 0.50mm larger in diameter than standard size. This is typically used when the crankshaft journals have been machined down (ground undersize) during a rebuild, or if you are seeking a slightly tighter oil clearance for performance applications.

Are these bearings suitable for a stock engine rebuild?

While these are high-performance bearings, they can be used in a stock engine rebuild if the crankshaft journals are in good condition and within the acceptable tolerance for the 0.50mm oversized size. However, they are particularly well-suited for performance builds where increased loads are expected.

What is the importance of using the correct oil clearance with these bearings?

Maintaining the correct oil clearance is critical for engine health. It ensures that the oil film between the bearing and the crankshaft is sufficient to lubricate and cool the surfaces, preventing metal-to-metal contact and premature wear, especially under high RPM and load.

Product Details

ACL has been making engine bearings for decades, and this 0.50mm oversized high-performance rod bearing set for your RB25DETT or RB26DETT engine is one of their staples. These bearings are crucial for keeping your engine running smoothly, especially when you're pushing it hard. They sit between the connecting rod and the crankshaft, allowing for smooth rotation while handling the immense forces involved. When you're rebuilding or upgrading an engine, especially one known for performance like the RB series, using well-built bearings is key to longevity and reliability.

This set is specifically designed to be 0.50mm oversized, which is important if your crankshaft journals have been machined down during a rebuild or if you're looking for a slightly tighter tolerance. ACL uses advanced materials and manufacturing processes to ensure these bearings can handle increased loads and higher RPMs. They are built to maintain oil clearance under stress, which is vital for preventing engine damage. If you're working on a performance build or a performance rebuild, these bearings are a solid choice to ensure your engine's bottom end can keep up.

When installing these bearings, always ensure your crankshaft journals are clean and within the specified tolerance for the 0.50mm oversized size. It's also important to use the correct assembly lube and torque specifications as outlined by the engine manufacturer or your performance build guide. Using a quality oil is also paramount for these high-performance bearings to function as intended.
