What does '0.25mm oversized' mean for these rod bearings?

This means the bearings are slightly larger than standard size. They are designed to be used when the crankshaft journals have been machined down by 0.25mm to ensure a clean surface and proper fit. It's important to measure your crankshaft journals to confirm they are within the correct range for these bearings.

Are these bearings suitable for a stock RB25DETT or RB26DETT engine?

While these are high-performance bearings, they are designed for engines that have been modified or are being rebuilt with performance in mind. For a completely stock engine with no machining, standard size bearings might be more appropriate. Always consult your engine build specifications.

What is the overlay plating on these bearings?

The specialized overlay plating is a feature designed to improve the bearing's resistance to wear and maintain its integrity under high stress. This helps ensure consistent lubrication and reduces friction between the bearing and the crankshaft journal.

Product Details

Already running upgraded engine components in your RB25DETT or RB26DETT? These 0.25mm oversized high-performance rod bearings from ACL are the next piece of the puzzle for a robust build. They are designed to handle the increased demands of a performance engine, ensuring reliable lubrication and reduced friction between the crankshaft and connecting rods. This is crucial for maintaining engine health under higher loads and RPMs.

ACL has been a well-known name in engine bearings for a long time, and these are built to last. They use a specialized overlay plating that helps them resist wear and maintain their shape even when the engine is working hard. The 0.25mm oversize is important; it means these bearings are designed to be used when the crankshaft journals have been machined down slightly to clean them up or account for wear. This ensures a proper, snug fit and the correct oil clearance, which is critical for oil pressure and bearing longevity.

When you're rebuilding or significantly upgrading an RB engine, paying attention to the details like bearing size and quality makes a big difference. Make sure to check your crankshaft journal dimensions to confirm they are within the range for these 0.25mm oversized bearings before installation. Proper installation according to manufacturer guidelines is key to achieving the performance and durability these bearings offer.
