King Engine Bearings GMC 2.4L (146cu) I4 Ecotec Main Bearing Set - (Size 1.0 Oversized)

If you're rebuilding the bottom end of your engine, getting the main bearings right is crucial for smooth operation and longevity. This main bearing set from King Engine Bearings is built for GMC 2.4L Ecotec engines, fitting a range of vehicles like the Chevrolet Cavalier, Pontiac Sunfire, and Buick Skylark.

These bearings are constructed with a bimetal aluminum silicon base, a well-built material that handles the stresses of engine rotation. This set is specifically sized at 1.0 oversize, meaning it's intended for crankshafts that have been machined down to accommodate this larger bearing size during an engine rebuild. Proper installation of these bearings ensures the crankshaft is supported correctly, reducing friction and wear.
