ACL 08+ Mitsubishi 4B11T Evo X Std Size High Perf w/ Extra Oil Clearance Main Bearing Se

Already running a built 4B11T engine for your Evo X? These ACL main bearings are the next piece of the puzzle. They're designed to handle the increased stress and heat that comes with a performance engine, offering a solid foundation for your build. ACL has been making engine bearings for a long time, and these are well-built for the job.

What sets these apart is the extra oil clearance. This is crucial for high-performance applications because it allows for a bit more oil flow around the crankshaft. This helps keep things cooler and better lubricated, especially under heavy load or at higher RPMs. They are standard size, meaning they're meant to be used with a crankshaft that hasn't been machined undersize. If your crankshaft has been reconditioned to standard size, these are what you'll need.

When you're rebuilding or heavily modifying an engine like the 4B11T, using quality bearings is essential for longevity and performance. These ACL bearings are a popular choice for a reason, offering a good balance of performance and reliability for your Lancer.
