King Engine Bearings Chevrolet 121Ci/Ln2 134Ci (Size +0.75mm) Main Bearing Set

If you're rebuilding the bottom end of a 1992-2003 Chevrolet Cavalier, or a similar GM vehicle from that era, this King Engine Bearings Main Bearing Set is what you'll need. These bearings are specifically made for medium-load engines and are designed to be a direct replacement for your stock main bearings, but with an important size difference: they are 0.75mm undersize. This means they are intended for crankshafts that have been machined down by 0.75mm to correct for wear or to achieve a specific clearance.

King specializes in bearings, and this set is constructed from a bi-metal aluminum material. It features a lead-free composite that's environmentally safe and ideal for the demands of these types of engines. When you're putting an engine back together, getting the bearing clearances just right is critical for oil pressure and long-term durability. Using a set like this, sized for a machined crankshaft, ensures you can achieve those proper clearances.
