Boss Comp S197 Ford Mustang Front Lower Control Arms w/ Ball Joints

Boss Comp S197 Mustang Front Lower Control Arms w/ Ball Joints

Boss Competition front lower arms use high-durometer urethane bushings and longer ball joints. Reduced compliance maintains alignment under braking/cornering, while the ball-joint geometry improves grip and reduces understeer and roll.

Designed for heavy loading and reportedly tested at Daytona above 150 mph/about 241 km/h.

Longer ball joints require at least 18-inch wheels with sufficient clearance.
