Granatelli Motor Sports - 3.50-Inch Billet Aluminum Hose Clamps

Upgrade your setup with 3.50‑inch Billet Aluminum Hose Clamps from Granatelli Motor Sports. Precision‑machined, universal‑fit clamps designed to deliver a secure, reliable seal across a wide range of performance and street applications. Available in multiple finishes and colors, including blue, red, standard, yellow, and black, these clamps let you match form with function under the hood. Built to firmly secure intake tubes, intercooler couplers, coolant hoses, and other 3.5-inch connections, they help prevent boost leaks, coolant seepage, and hose blow‑off caused by heat, pressure, and vibration. If you’re noticing cracked hoses, slipping connections, corrosion, or inconsistent boost or cooling performance, it’s a clear sign it’s time to replace worn clamps. Granatelli chooses billet aluminum, a solid block of aluminum precisely CNC‑machined—for its superior strength, lightweight properties, and excellent resistance to corrosion compared to stamped or cast alternatives. The result is a clamp that tightens evenly, looks great, and holds up in demanding environments like turbocharged builds, high‑RPM engines, race cars, off‑road vehicles, and custom projects. Trusted by enthusiasts and professionals alike, Granatelli’s billet aluminum hose clamps combine durability, performance, and clean aesthetics in a universal solution that simply works.
