What does '1.0mm oversize' mean for these bearings?

This means the bearings are slightly larger than standard size. They are intended for use when the engine's crankshaft has been machined down (ground) by 1.0mm to remove wear or damage. Always verify your crankshaft journal size before ordering bearings.

What is the construction of these main bearings?

These bearings feature a bimetal construction with an aluminum base. This design is chosen for its durability and ability to handle the heat generated during engine operation.

Are these bearings a direct replacement for all LX3 engines?

These bearings are specifically for General Motors LX3, 85ci, and 98ci engines, and are sized 1.0mm oversize. It's crucial to confirm your engine's specific requirements and crankshaft condition before installation.

About this part

Product Details

What you get in this box is a set of main bearings for your General Motors LX3, 85ci, or 98ci engine. Specifically, these are sized 1.0mm oversize, which is important if you're rebuilding an engine that has had its crankshaft ground down to this size. These bearings are made with a bimetal construction, meaning they have an aluminum base. This type of construction is common for main bearings because it offers good wear characteristics and helps manage heat.

If you're rebuilding the bottom end of your engine, main bearings are a critical component. They sit between the crankshaft and the engine block, supporting the crankshaft and allowing it to spin smoothly. Using a set of well-built bearings like these from King Engine Bearings is a solid option for ensuring your engine's longevity after a rebuild. Remember to always check your crankshaft journals for the correct size and condition before installing new bearings.
