What is the main advantage of ACL Race Series bearings?

The Race Series bearings are built for performance applications. They feature a tri-metal construction that offers a strong load-carrying capacity and good conformability, which is important for handling the stresses of modified or high-output V8 engines.

What does 'Standard Size' (STD) mean for these bearings?

Standard size bearings are meant to be used with a crankshaft that is within its original factory specifications. If your crankshaft has been machined undersize due to wear or repair, you would need a different size bearing set.

Are these bearings suitable for a daily driver with a stock engine?

While these bearings are well-built and reliable, they are specifically designed for performance applications. For a stock, daily driver engine, standard OEM-style replacement bearings might be a more appropriate choice unless you plan on modifying the engine for increased performance.

Product Details

ACL has been making engine bearings for decades, and this Race Series connecting rod bearing set for your Chevrolet V8 is one of their staples. These bearings are built for performance applications where durability and precise oil clearance are critical. They are designed to handle the increased stresses that come with modified or high-output V8 engines, ensuring your engine's rotating assembly stays properly lubricated and supported.

The Race Series bearings feature a tri-metal construction, which is a popular choice for performance builds. This construction offers a good balance of strength and conformability, allowing the bearing to adapt to the crankshaft surface while maintaining a strong load-carrying capacity. The standard size (STD) means they are intended to be used with a crankshaft that has not been machined undersize. It's important to ensure your crankshaft journals are within the manufacturer's specified tolerances for roundness and taper before installing these bearings.

When you're building or rebuilding a performance V8, the connecting rod bearings are a key component. This set from ACL is a solid option for those looking for reliable performance without breaking the bank. Make sure to follow the manufacturer's installation instructions carefully, paying close attention to lubrication and torque specifications to get the most out of these bearings.
