What does the '.25' size designation mean for these bearings?

The '.25' indicates that these bearings are 0.25 undersize. This means they are intended for use with a crankshaft that has been machined down by 0.00025 inches. This is a common practice during engine rebuilding to ensure proper oil clearance on a freshly ground crankshaft.

Are these bearings suitable for a stock engine rebuild?

Yes, these are high-performance bearings, but they are well-built and can be used in a stock engine rebuild. They offer improved strength and durability over standard bearings, which can be beneficial for engine longevity.

What other parts are typically needed when installing main bearings?

When installing main bearings, it's standard practice to also replace the connecting rod bearings. You'll also need new engine oil and an oil filter. Always refer to the manufacturer's service manual for specific installation procedures and torque specifications.

Whether you're restoring a Toyota Celica, Corolla, Matrix, or even a Lotus Elise or Exige, getting the main bearings right is crucial for engine longevity and performance. This set from ACL is a high-performance option designed to handle the demands of a rebuilt or performance-tuned engine.

ACL has been making engine bearings for a long time, and this set is built to be a solid option for your build. They're made with a specific material composition that's known for its strength and ability to handle higher loads and temperatures than stock bearings.
