What does the '0.025 Oversized' mean for these bearings?

The '.025' in the part number indicates that these main bearings are 0.025 inches undersize. This means they are intended for use when the crankshaft journals have been machined down to this specific size during an engine rebuild. It's crucial to match the bearing size to the machined crankshaft journal size for proper oil clearance.

Are these bearings suitable for a stock engine rebuild?

These are high-performance bearings, and the 0.025 inch undersize specification means they are intended for engines where the crankshaft has been machined. If your crankshaft is still at factory specifications, you would need a standard size bearing. Always confirm your crankshaft journal size before ordering.

What is the primary benefit of using ACL bearings?

ACL is known for producing well-built engine bearings that meet strict specifications. Using these bearings helps ensure the correct oil clearance and proper support for the crankshaft, which is vital for engine longevity, especially in performance or rebuilt applications.

About this part

Product Details

You get a full set of high-performance main bearings in this kit, which means one box handles a critical part of your engine rebuild. These ACL bearings are specifically sized at 0.025 inches undersize, designed to be a precise fit for the Hyundai G4KF 2.0T engine found in vehicles like the Genesis Coupe, Sonata, Forte, Optima, and Sportage. When you're rebuilding an engine, especially one with a turbo like the G4KF, getting the main bearings right is crucial for proper oil clearance and crankshaft support. These bearings are well-built to handle the demands of a performance application.

ACL has a solid reputation for making engine bearings, and this set is no exception. They're made to meet the specific requirements of the G4KF engine, ensuring the crankshaft spins smoothly within the block. The 0.025 inch undersize is important – it means these are intended for use when the crankshaft journals have been machined down to match this specific size during an engine rebuild. Using the correct size bearing is key to establishing the right oil film thickness, which protects the crankshaft and bearings from wear under load.

This set is a great choice if you're diving into a performance engine build or a thorough rebuild of your G4KF engine. Make sure to confirm your crankshaft journals have been machined to the 0.025 inch undersize specification before ordering. Proper installation, including cleaning and correct oiling procedures, is essential for the longevity of these bearings.
