What is the difference between standard size and undersize bearings?

Standard size bearings are meant for engines where the crankshaft journals are still at their original factory diameter. Undersize bearings are used when the crankshaft has been machined down to remove wear or damage, requiring a bearing with a slightly smaller inner diameter to compensate.

Do these bearings come with new hardware?

This set includes the main bearings themselves. It does not typically include new bolts or other hardware, which should be sourced separately if needed.

What else should I replace when installing main bearings?

When replacing main bearings, it's highly recommended to also replace your engine oil and oil filter. Inspecting and potentially replacing the crankshaft thrust bearing and rear main seal is also good practice during this type of engine work.

About this part

Product Details

This ACL main bearing set is built to replace the worn bearings in your Hyundai G4KC (Theta) 2.4L engine. These bearings are crucial for keeping the crankshaft properly supported and lubricated as it spins. When they wear out, you can get excessive bearing noise, oil pressure loss, and eventually, serious engine damage. This set is standard size, meaning it's meant to be installed in an engine with a crankshaft that hasn't been machined undersize. They are well-built to handle the demands of daily driving and keep your engine running smoothly.

This set includes the main bearings needed for your engine. Always refer to your vehicle's service manual for the correct installation procedure and any other related parts you might need, like new oil and a new oil filter, to ensure a proper repair.
