About this part

Product Details

If you're rebuilding the bottom end of your Cummins V903 V8 engine, this Clevite main bearing set is a solid option. These bearings are designed to replace the factory originals, ensuring proper crankshaft support and oil clearance. This particular set is 0.020 inches undersize, meaning it's intended for crankshafts that have been machined down to that specification to correct wear or runout.

Clevite is known for making well-built engine components, and these main bearings are no exception. They are constructed with durable materials to handle the stresses of a large displacement V8 engine. Proper installation is key; ensure your crankshaft journals are clean and within the specified tolerance for this bearing size. Using the correct oil viscosity is also important for longevity.
