About this part

Product Details

This is a King Engine Bearings main bearing set, specifically sized 0.75 inches oversized. It's built for GMC 2.4L I4 Ecotec engines, commonly found in a range of GM vehicles like the Chevrolet Cavalier, Pontiac Grand Am, and Oldsmobile Alero. Main bearings are critical for keeping your crankshaft supported and spinning smoothly within the engine block. When they wear out, you can experience low oil pressure and knocking noises, so replacing them is key to engine health.

These bearings are constructed with a bimetal design, featuring an aluminum silicon base. This material choice helps manage heat and wear, offering a solid option for rebuilding or repairing your engine. Because these are oversized by 0.75 inches, they are intended for use when the crankshaft journals have been machined down to match this specific size during an engine rebuild. Always ensure your crankshaft is properly machined to the correct undersize before installing these bearings.
