What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are designed for an engine where the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilds to ensure proper oil clearance with worn or resurfaced crankshafts.

What is the construction of these main bearings?

These main bearings feature a bimetal construction with an aluminum silicon base. This material combination is chosen for its balance of wear resistance and strength, suitable for supporting the crankshaft.

Are these bearings a direct replacement for all Saturn models listed?

Yes, these bearings are designed as a direct replacement for the main bearings in the specified Saturn SC1, SL1, SL, and SW1 models within their respective year ranges. Always confirm your specific engine's needs before installation.
