Mustang Ball Joints Extended Length 05-10 Ford Mustang S197 J&M Products

Mustang Extended Length Ball Joints 2005 2010 S197 J&M Products / Ingalls Engineering extended length ball joints are designed to raise the roll center back up after lowering your S197 Mustang. These extended length ball joints are a direct replacement for the factory ball joints and go in the same location as those that came with factory suspension. Raising the roll center makes for a great improvement in handling by reducing body roll, brake dive, and increased front tire contact patch without the need of increasing spring rate or roll bar stiffness.
The roll center of a vehicle is the notional point at which the cornering forces in the suspension are reacted to the vehicle body. There are two definitions of roll center. The most commonly used is the geometric (or kinematic) roll center; the Society of Automotive Engineers uses a force-based definition.
The location of the geometric roll center is solely dictated by the suspension geometry, and can be found using principles of the instant center of rotation. The SAE’s definition of the force based roll center is, the point in the transverse vertical plane through any pair of wheel centers at which lateral forces may be applied to the sprung mass without producing suspension roll.
The lateral location of the roll center is typically at the center-line of the vehicle when the suspension on the left and right sides of the car are mirror images of each other.
The significance of the roll center can only be appreciated when the vehicle’s center of mass is also considered. If there is a difference between the position of the center of mass and the roll center a moment arm is created. When the vehicle experiences angular acceleration due to cornering, the size of the moment arm, combined with the stiffness of the springs and anti-roll bars (anti-sway bars in some parts of the world), dictates how much the vehicle will roll. This has other effects too, such as dynamic load transfer.
Detaials:

• Mustang Extended Length Ball Joints 2005 2010 S197
• Improves braking and vehicle control
• Better handling for more stable predictable cornering
• Better suspension geometry
• larger tire contact patch under cornering and braking
• Due to the change in bumpsteer J&M highly recommends the use of a bumpsteer kit with these extended ball joints.
• Please Note: 18 Inch wheels are required for clearance
