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

This means the bearings are made to fit a crankshaft that has been machined down by 0.025 millimeters. This is common when a crankshaft has been worn or damaged and needs to be resurfaced to a smaller diameter. You must use the correct size bearing to match the machined crankshaft for proper oil clearance.

Are these bearings suitable for a stock engine rebuild?

Yes, these are a well-built option for a stock engine rebuild, especially if the crankshaft has been machined to the 0.025mm undersize specification. They are part of ACL's Race Series, which focuses on durability and performance for various engine builds.

What other parts might I need when installing main bearings?

When replacing main bearings, it's highly recommended to also replace the connecting rod bearings, oil pump, and all engine seals. You'll also need a quality engine oil that meets your vehicle manufacturer's specifications for proper lubrication and cooling.

Product Details

When you're rebuilding or refreshing a Honda J35 V6 engine, getting the crankshaft main bearings right is crucial for long-term health and performance. This set from ACL is specifically made for the J35 engine, which you'll find in many Acura and Honda vehicles. These are the main bearings, which support the crankshaft and allow it to spin smoothly within the engine block.

ACL's Race Series bearings are well-built with a focus on durability and performance. This particular set is 0.025mm undersize, meaning it's intended for a crankshaft that has been machined down to match this size. Using the correct undersize bearing is essential for proper oil clearance, which is key to preventing premature wear and ensuring the engine runs as it should. They're a solid option if you're looking for reliable components for your J35 build.

It's important to note that these bearings are designed for a machined crankshaft. Always refer to your vehicle's service manual for the correct oil clearance specifications and installation procedures. If your crankshaft doesn't require an undersize bearing, you'll need to select the standard size set.
