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

The Race Series bearings feature a tri-metal construction with a high-performance overlay. This design allows them to handle higher loads and temperatures compared to standard bearings, making them suitable for more demanding engine use.

Do these bearings come with installation hardware?

This set includes the conrod bearings themselves. It is recommended to refer to the manufacturer's installation instructions for any specific hardware or lubrication requirements.

Can I use these bearings if my crankshaft has been machined?

These are standard size bearings, intended for use with a factory-spec crankshaft. If your crankshaft has been machined, you would typically need undersize bearings. Always verify your crankshaft specifications before ordering.

About this part

Product Details

ACL has been making engine bearings for decades, and this Race Series conrod bearing set for your BMW M4 is one of their staples. These bearings are designed for engines that see more demanding use, whether that's spirited street driving or track time. They are a direct replacement for your stock rod bearings, fitting right into place without modification.

The Race Series bearings feature a tri-metal construction with a high-performance overlay. This design helps them handle higher loads and temperatures compared to standard bearings. They are manufactured to standard size, meaning they're intended to be used with a factory-spec crankshaft. If you're rebuilding your engine or looking for an improved bearing solution for your N20B20 or N26B20 engine, these are a solid option.

When installing these bearings, it's important to follow the manufacturer's recommended clearance specifications and lubrication procedures. Proper installation is key to ensuring their longevity and performance. If you've already got other engine upgrades, these bearings can be a good way to ensure your bottom end can handle the extra stress.
