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

This means the bearings are slightly larger in diameter than standard. They are designed to be used with a crankshaft that has been machined down by 0.25mm to ensure the correct oil clearance and a snug fit 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 rebuild if the crankshaft has been properly machined to the 0.25mm oversized specification. For a completely stock crankshaft, you would typically need standard size bearings.

What is the tensile strength of these bearings?

These ACL rod bearings have a tensile strength of 200,000 psi, which is significantly higher than stock hardware and indicates their suitability for demanding engine builds.

Product Details

200,000 psi tensile strength puts these ACL rod bearings well above stock hardware. If you're rebuilding or refreshing your SR20DE or SR20DET engine, especially for performance applications, these bearings are a solid choice. They're designed to handle the increased loads and stresses that come with a performance build, offering a reliable foundation for your engine's rotating assembly. This set is 0.25mm oversized, meaning they're intended for crankshafts that have been machined down to compensate for wear or to achieve a specific clearance. The 17mm width is specific to the SR20 engine family, ensuring a proper fit.

ACL has been making engine bearings for a long time, and these are well-built for the job. They use advanced materials and manufacturing processes to ensure consistent performance and durability. When you're installing these, remember that proper bearing clearance is critical for oil flow and engine longevity. Make sure your machine shop has set the correct clearances for your specific build, especially since these are oversized.
