The nut holding the drive sprocket on your oil pump can become loose over time.
There are countless stories of oil pump nuts coming loose and causing a no oil pressure situation costing thousands in repairs or replacement.
This oil pump nut has a hole EDM'd (Electrical Discharge Machined) on the flat to allow it to be safety wired to the oil pump sprocket.
The kit includes one oil pump nut and a longer than needed length of safety wire to secure it. It's a small price to pay for peace of mind.
