Maximum Motorsports Extreme-Duty series Adjustable Rear Lower Control Arms for the 1999-2004 Mustang improve traction and handling by reducing the unwanted deflection allowed by the stock soft rubber bushings and flexible stamped steel control arm.
Fits 1999-2004 Mustang with solid rear axle. Includes spring perch and swaybar mount.
Well suited for Mustangs:
Why should I use the Extreme-Duty control arms instead of the Heavy-Duty series? Mustangs with over 400 rwhp, and even those with less power that are launched hard from a standing start, may overload urethane bushings, leading to premature failure of the bushing. When you hit your Mustang's throttle pedal, all of the forces accelerating your car pass from the rear axle housing through the lower control arms and their bushings; that's what moves your Mustang forward. The harder the car accelerates on launch, the greater the forces on the lower control arm bushings. Higher forces lead to a shorter lifespan of urethane bushings. The oversized spherical bearings used in the MM Extreme-Duty adjustable ride height control arms are robust enough for a Mustang with 600 HP launching on slicks.
What if my Mustang has over 600 rwhp? MM's Drag Race series control arms are rated at 1,000 ft-lb of torque at the rear wheels.
Better by design

Does NOT fit
Can I use the MMRLCA-33 in a street or road racing application? Yes. The spherical bearings transmit only a little more noise and vibration than do urethane bushings. Spherical bearings allow all of the articulation needed for proper suspension movement, so there is no binding to hurt handling.
