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

This means the inside diameter of the bearing is slightly larger than a standard bearing by 0.25mm. This is typically used when the crankshaft journals have been ground down (undersized) during an engine rebuild, and these bearings help bring the oil clearance back to the manufacturer's specification.

Are these bearings sold individually or as a set?

This is a set of rod bearings. You will receive enough bearings to replace all the connecting rod bearings in your engine.

What is the proper oil clearance for my engine?

Proper oil clearance is crucial for engine health. Always refer to the specific service manual for your 1990-1993 Acura Integra's engine to find the exact recommended oil clearance range for the connecting rod bearings.

Product Details

When you're rebuilding or refreshing the engine in your 1990-1993 Acura Integra, getting the internal clearances just right is key. These ACL rod bearings are designed to be 0.25mm oversized, which is useful if your crankshaft journals have been machined down slightly during a rebuild. They help restore the correct oil clearance between the connecting rod and the crankshaft, which is critical for proper lubrication and engine longevity.

ACL has been making engine bearings for a long time, and these are well-built units. They are made to meet the demands of an engine rebuild, ensuring that the critical surfaces of your connecting rods and crankshaft have the right amount of oil film between them. Using the correct size bearing, whether it's standard or an undersize/oversize like these, is essential for preventing premature wear and ensuring your engine runs smoothly.
