What does '0.75mm undersize' mean for these rod bearings?

This means the bearings are manufactured to be 0.75mm smaller in diameter than a standard, full-size bearing. They are intended for use when the engine's crankshaft journals have been machined down by 0.75mm during a rebuild.

Are these bearings suitable for a stock, unmachined crankshaft?

No, these bearings are specifically 0.75mm undersize. They should only be used if your crankshaft has been professionally machined down by exactly 0.75mm. Using them on a stock crankshaft will result in incorrect oil clearance and potential engine damage.

Product Details

When you're rebuilding the engine in your 1990-1998 Hyundai Sonata, especially if you're dealing with a V6 2972cc 6G72 engine, getting the right internal components is critical. These ACL rod bearings are designed to be 0.75mm undersize, which is important if your crankshaft journals have been machined down during the rebuild process. Using the correct undersize bearing ensures a proper oil clearance, which is key for engine longevity and performance.

ACL has been making engine bearings for a long time, and they're known for their well-built products. These bearings are made to meet the demands of an engine rebuild, providing a solid foundation for your V6. The 0.75mm undersize means they're meant to be paired with a crankshaft that's been ground down by that amount. Getting the oil clearance just right is one of the most important steps in an engine rebuild, and using the correct undersize bearings helps you achieve that precision.

If you're in the middle of an engine overhaul for your Sonata, these ACL rod bearings are a popular choice. Make sure to confirm your crankshaft has been machined to the correct 0.75mm undersize before ordering, as using the wrong size bearing can cause serious engine damage.
