What does '0.025 Oversized' mean for these bearings?

This means the bearings are manufactured to be 0.025 inches larger in diameter than standard size. This is necessary when the crankshaft journals have been machined down by 0.025 inches during an engine rebuild to correct wear or damage. Using the correct size bearing ensures proper oil clearance and oil pressure.

What is the benefit of the CT-1 coating?

The CT-1 coating is an advanced surface treatment that helps reduce friction between the bearing and the crankshaft. It also improves oil retention, which is particularly beneficial during engine startup and under high-load conditions, helping to protect the bearing from wear.

Are these bearings suitable for a stock engine rebuild?

These are high-performance bearings with a CT-1 coating and are 0.025 inches oversized. They are best suited for performance engine builds or for rebuilds where the crankshaft journals have been machined undersize. For a stock engine rebuild with unmachined journals, standard size bearings would typically be required.

Product Details

ACL has been making engine bearings for decades, and this high-performance rod bearing set for your Acura or Honda K-series engine is one of their staples. These bearings are built to handle the demands of performance engines, whether you're building a track car or just want a more robust setup for your daily driver. They are 0.025 inches oversized, which is crucial for engines that have had their crankshaft journals machined down during a rebuild. This ensures a proper, snug fit on the crankshaft, which is essential for oil pressure and engine longevity.

What sets these bearings apart is the CT-1 coating. This advanced coating helps reduce friction and improve oil retention, especially during startup when oil pressure is still building. This means less wear on the bearings and the crankshaft, which is especially important in high-performance applications where clearances are tighter and loads are higher. The bearings themselves are well-built with a strong internal structure designed to maintain their shape under stress.

When rebuilding or refreshing a K20A2 or K24A engine, especially if the crankshaft has been reconditioned, using the correct size bearings is critical. These 0.025 inch oversized bearings are designed to work with journals that have been machined down by that amount. Always refer to your engine's service manual for specific installation procedures and torque specifications.
