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

This means the bearings are slightly larger than the standard size. They are intended to be used with a crankshaft that has been machined down by 0.25mm, or to compensate for existing wear on the crankshaft journals. This helps ensure proper clearance for oil flow and bearing function.

Are these bearings sold individually or as a set?

This is a set of rod bearings. Typically, a set includes all the bearings needed for the connecting rods on your engine.

What is the typical application for oversized bearings?

Oversized bearings are commonly used during engine rebuilds. They are essential when the crankshaft journals have been ground undersize to remove damage or to achieve a specific bearing clearance.

Product Details

Already running a built engine? This rod bearing set is the next piece of the puzzle for your 1989-1991 Hyundai Sonata. These bearings are designed to replace your stock rod bearings, and they're sized 0.25mm oversized to help account for wear or to be used with a crankshaft that's been machined to match. ACL has been making engine bearings for a long time, and they're known for making well-built parts that hold up.

When you're rebuilding an engine, especially one that's seen some miles or is being built for more power, getting the bearing clearances just right is critical. These bearings are made to precise tolerances, ensuring they fit correctly and provide the proper oil clearance. Using the correct size bearing, whether it's standard or an undersize/oversize like these, is key to oil pressure and the longevity of your engine build.
