What does the 1.25mm undersize mean for these bearings?

The 1.25mm undersize specification indicates that these bearings are intended for use with a crankshaft that has been machined down by 1.25mm (approximately 0.050 inches). This is typically done during an engine rebuild to account for wear or to achieve specific clearances.

What type of engine applications are these bearings best suited for?

These main bearings feature a bimetal aluminum base construction, making them a well-built option for engine rebuilding and repair. They are specifically listed for Opel engine codes like C16SE, X14XE, and Z16LE.

Do these bearings come with installation hardware?

This product is a main bearing set and typically includes only the main bearings themselves. Installation hardware, such as main bearing bolts or seals, are usually sold separately and should be replaced according to your vehicle's service manual.

About this part

Product Details

Built with a bimetal aluminum base, this main bearing set from King Engine Bearings is designed for engine rebuilding. The 1.25mm undersize specification means these bearings are intended for crankshafts that have been machined down by 0.050 inches, which is common when addressing wear or during a performance rebuild.

This set is specifically made for engines like the Opel C16SE, X14XE, and Z16LE, which are found in vehicles like the Chevrolet Aveo. King Engine Bearings uses a tri-metal construction for their performance bearings, but this particular set utilizes a bimetal aluminum base, offering a solid option for many engine applications where a reliable bearing surface is needed. Proper installation is key, so always refer to your vehicle's service manual for correct procedures and torque specifications.
