What is the difference between Race Series and standard main bearings?

Race Series bearings are built with a tri-metal material and a stronger overlay to withstand higher loads and stresses commonly found in performance or rebuilt engines. Standard bearings are designed for everyday driving conditions.

Are these bearings a direct fit for my engine?

These are standard size (STD) main bearings, meaning they are a direct replacement for your original bearings if your crankshaft journals are within factory specifications. If your crankshaft has been machined or is out of spec, you may need undersize bearings.

What else might I need when installing these main bearings?

During an engine rebuild, you'll typically need new main bearing bolts, assembly lube to coat the bearings before installation, and potentially a torque wrench to ensure proper tightening according to manufacturer specifications.

About this part

Product Details

When you're rebuilding or upgrading your Hyundai or Kia V6 engine, especially if you're pushing it hard, a solid set of main bearings is crucial. These Race Series main bearings from ACL are built to handle the extra stress that comes with performance driving. They're made with a tri-metal material that offers good embeddability and a strong overlay for durability under high loads. The standard size means they're a direct replacement for your original bearings, assuming your crankshaft journals are still within factory specifications.

If you're already running an upgraded engine or planning to, these bearings are a smart choice to ensure your bottom end stays strong. They're designed to work with your existing crankshaft and block, making them a straightforward component to install during an engine rebuild. Just be sure to check your crankshaft journals for any wear or damage before installing, as these are standard size bearings.
