Just like our high-torque worm gear clamps, Mishimoto's Constant Tension Worm Gear Clamps are an effective solution to a wide range of clamping needs. Where this 3.27in - 4.13in (83mm - 105mm) constant tension worm gear clamp excels, however, is in high-temperature applications. The spring on the adjustment bolt allows the clamp to exert continuous pressure through a wide range of temperatures to ensure your parts stay clamped as strong as the day you installed them. This 3.27in - 4.13in (83mm - 105mm) constant tension worm gear clamp is made from stainless steel to weather any environment and ensure a tight seal for years to come. Our constant tension worm gear clamps are also available in a wide variety of other sizes to suit everything from coolant lines to intake pipes. Like all Mishimoto products, this 3.27in - 4.13in (83mm - 105mm) constant tension worm gear clamp is backed by our Mishimoto Lifetime Warranty.
