What does '0.25mm undersize' mean for these bearings?

This means the bearings are manufactured to be 0.25 millimeters smaller in diameter than a standard, or '0.00' size bearing. This size is used when the crankshaft journals have been machined down by 0.25mm to remove imperfections or to prepare for a rebuild.

What is the construction of these bearings?

These bearings are made with a bimetal construction, which uses an aluminum base. This type of construction is known for its good load-carrying capacity and ability to manage heat effectively within the engine.

Are these bearings sold individually or as a set?

This product is sold as a set of four main bearings. This is the typical quantity needed for the specified Honda and Acura engines that use this bearing type.

About this part

Product Details

King Engine Bearings is known for making solid engine bearings. If you're rebuilding the engine in your 1996-2004 Acura RL, especially if it has the C32A1, C32A6, or C35A1 engine, this main bearing set is what you'll need. These bearings sit between the crankshaft and the engine block, supporting the rotating assembly and ensuring smooth operation.

This set is built with a bimetal construction, meaning it has an aluminum base. This design helps with heat dissipation and load-carrying capacity. Since this set is 0.25mm undersize, it's intended for crankshafts that have been machined down by that amount during an engine rebuild. Using the correct size bearing is crucial for proper oil clearance and engine longevity.

This is a set of four bearings, which is what you'll typically need for these engines. Make sure to check your crankshaft's condition and machining specifications before ordering to ensure this 0.25mm undersize set is the right fit for your rebuild project.
