What does '0.025mm 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 0.025mm during an engine rebuild. This ensures a fresh surface for the bearings to run on and helps achieve the correct oil clearance.

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 journals have been machined to the correct 0.025mm undersize. For a completely stock rebuild without machining, you would typically need standard size bearings.

What other parts are typically needed when installing rod bearings?

When installing rod bearings, it's essential to have the crankshaft journals properly machined and measured. You'll also need new engine oil and oil filter, and it's often recommended to replace rod bolts as they can be torque-to-yield. Always refer to your vehicle's service manual for specific procedures.

Product Details

Already running headers and a performance cam on your SR20DE or SR20DET? This set of ACL high-performance rod bearings is the next piece of the puzzle for a solid engine rebuild. These bearings are 0.025mm oversized, meaning they're designed to be used when the crankshaft journals have been machined down by 0.025mm to ensure a fresh, tight fit. They are 17mm wide, which is the standard width for these applications, ensuring proper contact area with the crank journals.

ACL has been making engine bearings for a long time, and these are well-built for the demands of a performance engine. They use a tri-metal construction that offers good strength and wear resistance, which is important when you're pushing your engine harder. When you're rebuilding an engine, especially one that's been modified, getting the bearing clearances right is critical for oil pressure and longevity. These bearings help you achieve that precise fit.

When you're rebuilding your SR20, make sure you have all the necessary components. It's always a good idea to check your crankshaft journals for straightness and wear before installing new bearings, and refer to your engine's service manual for the correct oil clearance specifications.
