Granatelli Motor Sports - 4.00-Inch Billet Aluminum Hose Clamps

Engineered for both performance and style, Granatelli Motor Sports 4.00-inch billet aluminum hose clamps are a premium upgrade for any automotive build where reliability matters. Designed to securely seal large-diameter hoses, these universal-fit clamps are ideal for use on intake systems, intercooler piping, radiator hoses, boost tubes, and other high-performance fluid or air connections. Precision-machined from billet aluminum, a solid block of aluminum is CNC cut to exact tolerances. These clamps offer superior strength, consistency, and corrosion resistance compared to stamped or cast alternatives, which is exactly why Granatelli chose billet for this application. Available in multiple finishes, including blue, red, gold, black, and standard aluminum, they not only hold firm under heat, vibration, and pressure, but also add a clean, professional look under the hood. It’s time to replace hose clamps if you see corrosion, stripped hardware, uneven clamping, leaks, or if you’re upgrading components where failure isn’t an option. Backed by Granatelli Motor Sports’ decades-long reputation for racing innovation and high-performance engineering, these 4.00-inch billet aluminum hose clamps deliver the strength, precision, and confidence enthusiasts expect on the street, at the track, or anywhere in between.
