StopTech Cryo-Stop High-Performance Brake Rotors are engineered to provide improved cooling and superior durability. These rotors undergo a specialized cryogenic treatment that stress-relieves the metal, resulting in a significantly longer service life and increased resistance to thermal warping. Featuring a G3000 metallurgy and a protective E-coat finish to prevent corrosion, these rotors are an ideal upgrade for heavy-duty use or performance driving. This part (120.44146CRY) is a single front brake rotor. For a complete axle set, please order two units. Part Number included: 120.44146CRY (1pc).
