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

This means the bearings are manufactured to be 0.025mm smaller in diameter than standard size. This is typically used when the crankshaft journals have been machined undersize to clean up wear or achieve tighter tolerances during an engine rebuild.

What engine families do these ACL bearings fit?

These bearings are designed for Hyundai Theta engines (G4KA, G4KC, G4KD, G4KE, G4KG, G4KJ) and Theta II engines (G4KF, G4KH, G4KL), including the 2.0T variants.

Are these bearings suitable for a stock engine rebuild?

While these are high-performance bearings, they can be used in a stock rebuild if the crankshaft journals have been machined to the 0.025mm undersize specification. For a standard rebuild without machining, you would typically need standard size bearings.

Product Details

When you're rebuilding or tuning a Hyundai G4KF 2.0T engine, getting the right bearings is crucial for longevity and performance. This set from ACL includes connecting rod bearings that are 0.025mm (0.001 inches) undersize. This specific sizing is important for engines that have had their crankshaft journals machined undersize to clean up wear or to achieve a tighter tolerance during a performance build.

ACL has been making engine bearings for a long time, and they're known for well-built parts. These bearings are designed to handle the demands of a performance 2.0T engine, offering a solid option for your rebuild. Using the correct undersize bearings ensures proper oil clearance, which is vital for keeping your engine running smoothly and preventing premature wear, especially when you're pushing the engine harder than stock.

This set is verified to fit a range of Hyundai and Kia models equipped with the G4KA, G4KC, G4KD, G4KE, G4KG, G4KJ (Theta) and G4KF, G4KH, G4KL (Theta II) engines, including the 2.0T variants. Make sure to check the fitment details to confirm compatibility with your specific vehicle. When installing, always refer to the manufacturer's service manual for the correct procedures and torque specifications.
