What is the difference between standard size and undersize rod bearings?

Standard size bearings are meant to be used with the original, factory-spec crankshaft journals. Undersize bearings, like those marked -010 or -020, are used when the crankshaft has been machined down to correct for wear or to achieve a specific clearance.

Do these bearings come with installation instructions?

While specific instructions are not included with this listing, it is critical to refer to the manufacturer's official installation guide. Proper lubrication and torque specifications are essential for the longevity of these high-performance bearings.

What else might I need when installing rod bearings?

When replacing rod bearings, it's common practice to also replace the main bearings and check the crankshaft for straightness and wear. You'll also need assembly lube and potentially new rod bolts if they are stretch-to-yield.

About this part

Product Details

Already running a built engine or planning for one? This rod bearing set from ACL is a key component for ensuring your 4G94 2.0L inline 4 engine can handle increased power. These are standard size bearings, meaning they're designed to fit the original crankshaft journals without modification, making them a straightforward replacement during an engine rebuild or upgrade. ACL has been making engine bearings for a long time, and these are well-built for performance applications.

When you're pushing an engine harder, the demands on the rod bearings increase significantly. These ACL bearings are made with a high-performance overlay material that helps them withstand higher loads and temperatures compared to stock bearings. This means better protection for your crankshaft and connecting rods, especially if you've already upgraded other engine components like pistons or cams. They are designed to maintain oil clearance within specification under stress, which is crucial for preventing premature engine wear.

If you're rebuilding your Lancer's engine for more power, or just want the peace of mind that comes with using a solid component during a standard rebuild, this ACL rod bearing set is a popular choice. Make sure to follow the manufacturer's installation instructions carefully, as proper lubrication and torque are critical for bearing longevity.
