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

A 1.0mm undersize bearing set means the bearing's inner diameter is slightly larger than standard. This is because the crankshaft journals have been machined down by 1.0mm to remove wear or damage. These bearings are specifically made to fit that machined crankshaft.

What is the construction of these main bearings?

These bearings are made with a bimetal construction, utilizing an aluminum silicon base. This material is chosen for its durability and performance in supporting the crankshaft.

Do I need to machine my crankshaft to use these bearings?

Yes, these are a 1.0mm undersize bearing set. They are intended for use when the crankshaft journals have been machined down by 1.0mm to address wear or damage. If your crankshaft is still at standard size, you would need a standard size bearing set.

Product Details

If you're rebuilding the bottom end of your 2009-2013 Suzuki Grand Vitara or Kizashi with the J24B engine, a fresh set of main bearings is essential. These bearings sit between the crankshaft and the engine block, supporting the rotating assembly and ensuring smooth operation. King Engine Bearings offers this set specifically for the J24B, helping you get your engine back in reliable running order.

This set features bimetal construction with an aluminum silicon base, a common and well-tested material for engine bearings. It's important to note that these are a 1.0mm undersize set. This means they are designed to be used when the crankshaft journals have been machined down by 1.0mm to clean up wear or damage. Using the correct size bearing is critical for proper oil clearance and engine longevity.
