Key your Duramax crank shaft in your own driveway with your own tools. Empire Performance Engineering specifically designed this crank shaft pin kit to fix the all too common shearing of factory dowel pins. This kit can be used on stock or heavily modified vehicles. It has a very simple procedure that can be done by your average skilled mechanic.
Due to Duramax's crank shaft poor design process of keying drive gears a random light vibration can found during idle. This is found after dampers spin on the crank shaft snout by shearing factory key. If you were to continue driving with this issue it can raise concerns in regards to harsh harmonics to balancing of the crank shafts.
This tool and procedure will put your mind at ease towards maintaing good harmonics and balancing of the crank shaft. All this without losing durability and reliability.
