2005-2010Ford Mustang X5 Ball Jointsby Steeda Autosports Steeda\’s X5 balljoints are designed to raise the roll center of your S197 Mustang which becomes lower as a result of lowering with lowering springs. Raising the roll center eliminates the issues associated with the lower roll center, making for a great improvement in handling by reducing body roll and improving the front tire contact patch without increasing spring rate or roll bar rate. Steeda balljoints are made in the USA by a respected name-brand supplier to Ford, GM and Daimler Chrysler. Except for their custom length, they are the same materials and construction that has been extensively tested in Panther applications, that is, police cars and other severe duty applications, where they have demonstrated durability that exceeds current production \”regular\” balljoints. They meet Ford\’s standards for friction, wear, and durability. Steeda\’s X5 ball joints change the bump steer geometry. Steeda highly recommends a bump steer kit be used in conjunction with the X5 balljoints.
