Strengthen a Factory Block to Handle the Horsepower of an Aftermarket Block up to 500+ HP
Main girdles are made of high-strength steel that expands at the same rate as the block to prevent the binding that occurs when using a different metal like aluminum. Valley girdles eliminate engine distortion and cracking by securing both sides of the lifter valley.
