Probe Industries Main Web Girdles are categorized into two distinct series, Dominator and Street Fighter for the performance usage level in mind. Main Web Girdles are manufactured to assist in strengthening the main webs of Ford passenger car engine blocks in high horsepower applications. In our experience using a Probe Industries Main Girdle greatly decreases, or eliminates, flex in both the main webs and the main caps. This reduces the requirement of replacing the main caps in all but the most violent applications. Available for Big Block Ford, Small Block Ford and 4.6L Ford applications.
