Clevite GMC Truck Diesel 500 CID Eng 4.252in Bore Piston Pin Bushing

Clevite is a well-known name for engine bearings and related components, and this piston pin bushing is no exception. It's a crucial part for the health of your engine's connecting rod assembly. This bushing sits inside the connecting rod and allows the piston pin (wrist pin) to pivot smoothly, which is essential for transferring power from the piston to the crankshaft without excessive wear or friction. If you're rebuilding or repairing the engine in a GMC truck or diesel vehicle, especially one with a 500 CID engine and a 4.252-inch bore, this bushing is a key component to get right.

This particular bushing is designed to fit a wide range of vehicles, including popular models like the Chevrolet C1500, Chevrolet C2500, and AM General Hummer from various years. Ensuring the piston pin has a solid, well-lubricated surface to rotate against prevents premature wear on both the pin and the connecting rod itself. When installing, make sure the connecting rod bore is clean and free of debris to allow for proper seating and function.
