What does the 0.025mm undersize mean for my engine?

The 0.025mm undersize specification means these bearings are slightly smaller than standard size. This is useful if the crankshaft journals on your engine have been machined down to a smaller diameter during a rebuild to remove wear or damage. It ensures the correct oil clearance is maintained.

What is the main function of rod bearings?

Rod bearings sit between the connecting rod and the crankshaft. Their primary job is to reduce friction and wear by providing a smooth surface for the crankshaft to rotate against, while also maintaining a precise oil clearance to lubricate and cool the components.

Do these bearings come with new hardware?

This product listing is for the rod bearing set only. It does not include any additional hardware. It is recommended to consult the manufacturer's installation guide for any specific hardware requirements or recommendations.

Product Details

ACL has been making engine bearings for decades, and this rod bearing set for your 2008-2015 Mitsubishi Lancer is one of their staples. These bearings are designed for the 4B11T engine, which is common in the Lancer Evolution models. Rod bearings are critical for keeping the crankshaft spinning smoothly within the engine block, and a good set ensures proper oil clearance for longevity and performance.

This particular set is 0.025mm undersize, which is helpful if your crankshaft journals have been machined down slightly due to wear or previous rebuilds. ACL uses well-built materials to create bearings that can handle the demands of a performance engine. They are designed to maintain consistent oil film thickness, which is crucial for reducing friction and heat buildup, especially when you're pushing the engine harder.

When installing these bearings, it's important to ensure your crankshaft journals are clean and within the specified tolerance for the 0.025mm undersize. Always refer to the manufacturer's installation instructions for proper torque specifications and any specific assembly procedures.
