What does 'undersize 0.025 inch' mean for these bearings?

This means the bearings are manufactured to be 0.025 inches smaller in diameter than standard size. They are used when the engine's crankshaft journals have been machined down (ground) to remove wear or damage, and this undersize dimension matches the ground journal size.

What is the main advantage of ACL Race Series bearings?

The Race Series bearings feature a special overlay material that offers improved resistance to fatigue and wear. This makes them a popular choice for builders who need a more robust bearing solution for engines that will be operated under higher stress or with more aggressive tuning.

Do these bearings come with installation instructions?

While this kit includes the main bearings, detailed installation procedures and torque specifications are not included. It is essential to consult your vehicle's specific service manual for proper installation to ensure correct oil clearance and engine longevity.

About this part

Product Details

You get a full set of race series main bearings in this kit, which means one box handles the critical bottom-end engine rebuild. These ACL bearings are built for performance applications, helping to keep your engine running smoothly under demanding conditions. They are specifically made to be 0.025 inches undersize, which is important when you're rebuilding an engine that has had some wear on the crankshaft journals.

ACL has been making engine bearings for a long time, and their Race Series is a popular choice for builders who want a well-built part that can handle more stress than stock. These bearings use a special overlay material that's designed to resist fatigue and wear, especially important if you're pushing your engine a bit harder or if the engine has higher mileage. When installing, make sure your crankshaft journals are clean and within the specified tolerance for the 0.025 inch undersize; this ensures a proper oil clearance and long life for your engine build.

This set is designed to fit a range of Holden, Opel, and Pontiac 4-cylinder engines from 1982 onwards, including your Daewoo Leganza, Nubira, and Suzuki Reno. Always refer to your vehicle's specific service manual for detailed installation procedures and torque specifications to ensure a correct and lasting engine rebuild.
