Ford Racing forged crankshaft sprocket for 2015–2017 Mustang GT 5.0L is a high-strength forged steel sprocket intended for race applications. It is substantially stronger than the factory powdered-metal sprocket and is specified to help avoid sprocket failure under increased horsepower, higher RPM, or when belt-mounted power adders are used, protecting the engine from related timing-system damage.
