About this part

Product Details

This is a main bearing set for your Opel C25XA or X25XA engine, which is found in the 1997-2001 Cadillac Catera, as well as certain Saab models. These bearings are a critical part of your engine's rotating assembly, supporting the crankshaft and ensuring it spins smoothly within the engine block. This particular set is sized at +0.50mm, meaning it's intended for engines where the crankshaft journals have been machined down by 0.50mm during a rebuild or repair.

King Engine Bearings uses a bimetal construction with an aluminum silicon base for these bearings. This material choice helps manage heat and wear effectively, providing a solid foundation for your engine's crankshaft. Because these are main bearings, they are designed to handle the significant loads placed on the crankshaft during operation. They fit right into the specified engine applications, making them a straightforward replacement part for a rebuild.
