What is the difference between standard and undersize bearings?

Standard size bearings are meant to be used when the crankshaft journals are still within their original factory specifications. Undersize bearings are used when the crankshaft has been machined down to remove damage or wear.

Do these bearings come with installation instructions?

This part does not include installation instructions. It is recommended to refer to the manufacturer's service manual or consult a professional mechanic for proper installation procedures.

What other engine components should I check when replacing main bearings?

When replacing main bearings, it's a good idea to inspect your crankshaft journals for wear or damage, check your connecting rod bearings, and ensure your oil pump is functioning correctly to maintain proper oil pressure.

Product Details

This ACL main bearing set is built for the 4B11T engine found in the Mitsubishi Lancer. Main bearings are critical for keeping your crankshaft spinning smoothly within the engine block. When they wear out, you can experience increased engine noise, oil pressure issues, and eventually, severe engine damage. These are designed as a high-performance replacement, meaning they're made with materials and tolerances that can handle more stress than stock bearings, which is important if you're pushing your Evo X harder.

This set includes standard size bearings, so they're a direct replacement if your crankshaft is still within factory specifications. If you've had your crankshaft machined undersize, you'll need a different bearing size. Always check your engine's condition before ordering parts.
