What does the '+1.0mm' size designation mean for these bearings?

The '+1.0mm' indicates that these bearings are 1.0mm thicker than standard size. They are designed to be used when the crankshaft journals have been machined down by 1.0mm to remove wear or damage, restoring proper clearance.

What is the construction material of these main bearings?

These main bearings are made with a bimetal construction, utilizing an aluminum base. This design is chosen for its oil retention properties and wear resistance, which are important for engine longevity.

Are these bearings a direct replacement for the original equipment manufacturer (OEM) parts?

While these bearings are designed to fit the specified Suzuki and Chevrolet engines, they are an aftermarket part. Always consult your vehicle's service manual to ensure compatibility and proper installation procedures.

About this part

Product Details

If you're rebuilding the engine in your 2007-2013 Suzuki SX4, this main bearing set from King Engine Bearings is a key component. These bearings are designed for the J18K and J20A engines, and this specific set is sized +1.0mm, meaning they are intended for use when the crankshaft journals have been machined down by 1.0mm to clean up wear or damage.

King Engine Bearings uses a bimetal construction with an aluminum base for these main bearings. This material choice helps ensure good oil film retention and wear resistance, which are critical for the health of your engine's rotating assembly. Installing bearings of the correct size is crucial for maintaining proper oil pressure and reducing friction between the crankshaft and the engine block.

When you're doing an engine rebuild, especially if the crankshaft has been machined, using the correct size bearings like these +1.0mm mains is essential for a successful outcome. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
