Collection: 3.75-Inch Billet Aluminum Hose Clamps

Here you will find 3.75-inch Billet Aluminum Hose Clamps from Granatelli Motor Sports, designed to deliver a secure, precise seal for high-performance plumbing throughout your vehicle. These universal-fit hose clamps are available in multiple finishes and colors, including blue, red, standard, yellow, and black, making it easy to match your engine bay’s style while maintaining professional-grade function. Designed to clamp evenly and reliably, they help prevent leaks and hose blow-off on applications such as coolant hoses, intake tubing, intercooler piping, turbocharger connections, and radiator outlets. Hose clamps should be replaced if you notice corrosion, stripped fasteners, uneven clamping pressure, or recurring leaks, especially after engine upgrades or increased boost and heat. Granatelli chose billet aluminum, which is precision-machined from a solid block of aluminum rather than cast, resulting in superior strength, consistent tolerances, lighter weight, and excellent corrosion resistance. Combined with Granatelli’s decades of racing and engineering experience, these Granatelli billet aluminum hose clamps offer reliable holding power, clean aesthetics, and long-term durability, making them a smart upgrade for both street and track builds.
