Granatelli Motor Sports, or GMS, is a maker of high quality performance components for many different makes and models of vehicles, including GMC Sierra trucks, ranging from 2007-2017 exterior parts like bumper accessories to 1999-2017 exhaust components, with lots more besides. With very skilled design and engineering departments at their disposal, GMS makes practical and effective components that produce real-world power boosts, such as their 2007-2017 mass air meters and performance MAF sensors. Their 2007-2017 bumpers components include 2” hitch receivers with built-in winch towers that make winching a boat or vehicle onto your Sierra’s trailer straightforward and effective. GMS’s flanges with V-clamps provide a method of solidly attaching sections of tubing together when you’re custom-building an exhaust system, are part of their 2007-2017 exhaust accessories range. Granatelli’s components come with a 90-day warranty against defects so that you can install and use them with confidence.
