The 1979-1998 Mustang BBK Gripp Rear Control Arm Kit eliminates deflection for firmer launches and much improved handling characteristics. These control arms eliminate deflection in 2 ways. The strong boxed steel tubing is much less flexible than the bent sheet steel factory control arms and polyurethane bushings are a higher durometer (stiffer), which cuts down on bushing deflection. The addition of the BBK upper control arm helps further eliminate deflection, keeping the rear axle squared to the chassis for maximum handling performance.
