What does the '+.002' size mean for these bearings?

The '+.002' or '+0.50mm' indicates that these bearings are slightly smaller than standard size. They are designed to be used when the engine's crankshaft has been machined down by 0.002 inches to correct for wear. This ensures a proper fit and oil clearance on a reconditioned crankshaft.

What is the material of these main bearings?

These bearings feature a bimetal construction with an aluminum silicon base. This material is chosen for its ability to withstand the high loads and temperatures found within an engine's main bearing journals.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings required for your engine's crankshaft installation.

About this part

Product Details

These main bearings are built with a bimetal construction, using an aluminum silicon base. This material choice is key for handling the stresses inside your engine. They are a +.002 inch (or 0.50mm) undersize version, meaning they're intended for crankshafts that have been machined down to compensate for wear. This is a common step when rebuilding an engine to bring it back to proper specifications.

This set is specifically made for Chevrolet engines with 121ci or LN2 134ci displacements. They are designed to fit right into the 1990-1991 and 1995-2002 Chevrolet Cavalier, as well as the Beretta and Corsica from the same early years. If you're working on a Chevrolet S10 or GMC Sonoma from the mid-90s to early 2000s with these engine sizes, these bearings will also be the correct fit.
