What does 'undersize' mean for these bearings?

The 'undersize' designation, in this case 0.025 inch, means these bearings are designed to fit crankshaft journals that have been machined down by 0.025 inches. This is common during engine rebuilds where the crankshaft may have been ground to remove imperfections.

Are these bearings suitable for daily driving or just racing?

While labeled 'Race Series,' these bearings are well-built and can offer improved durability for daily drivers, especially those who push their vehicles. They are designed to handle more stress than standard bearings, offering a solid option for performance-oriented builds or heavy-duty use.

What else might I need when installing these connecting rod bearings?

You'll need to ensure your crankshaft journals are clean and properly measured for the 0.025 inch undersize. It's also critical to have the correct torque wrench to tighten the connecting rod bolts to manufacturer specifications, and often new rod bolts are recommended.

Product Details

ACL has been making engine bearings for decades, and this Race Series connecting rod bearing set for your 2005 Ford F-150 is one of their staples. These bearings are crucial for keeping your V8 engine running smoothly, as they sit between the crankshaft and connecting rod to reduce friction and wear. If you're rebuilding your engine or looking to improve its performance and durability, a fresh set of high-quality bearings is a smart move.

This particular set is designed for the Race Series, meaning they're built to handle more demanding conditions than standard bearings. They are 0.025 inches undersize, which is important if your crankshaft journals have been machined down during a rebuild. ACL uses well-built materials and precise manufacturing to ensure these bearings offer solid performance and longevity, helping to protect your engine's rotating assembly under stress.

When installing these bearings, make sure your crankshaft journals are clean and within the specified tolerance for the 0.025 inch undersize. It's always a good idea to refer to your vehicle's service manual for the correct installation procedures and torque specifications.
