- Direct replacement for the stock lower control arm.
- Tubular steel construction is over three times stiffer than the stock control arm.
- Large 2" diameter round steel tube provides maximum stiffness.
- Engineered design prevents binding of suspension movement.
- Large Teflon-lined spherical bearings at each end allows freedom of motion for both pivoting and angularity, preventing unwanted deflection while still allowing the angularity required for proper articulation.
- Spherical bearings prevent damage to the torque-boxes by easily allowing the suspension to move as needed.
- Greatly reduces axle wind-up.
- Moderate change in NVH.
- Swaybar mounting brackets are 3/16" thick steel, shaped to increase their strength, and are welded on both sides.
- Powdercoated black
- Spring perch location on non-adjustable arms does not change ride height.
- Available with adjustable height spring perch
Rear lower control arms with spherical bearings at each end:
- Precisely locate the rear axle
- Do not deflect fore-and-aft
- Reduce axle wind-up
- Reduce wheel hop
- Do not cause suspension binding
- Stop torque-box damage
- Improve traction!
Muscle Mustangs and Fast Fords magazine tested the MM Extreme-Duty Rear Lower Control Arms in the January 2003 issue, as part of their test of the MM Street & Strip Box. They found the car's 60-foot times to be remarkably consistent, varying only .02 seconds over the course of 10 runs.
To adjust, or not to adjust...
Extreme Duty control arms are available in two styles: Ride height adjustable or non-adjustable.
Adjustable Extreme Duty control arms
- Allows easy changes to ride height, both up and down.
- Raise the rear ride height by up to 2 inches.
- Lower the rear ride height by as much as 1 inch.
- Adjust ride height without the need to jack the car off the ground.
- Improve traction by fine-tuning the instant center location and anti-squat geometry by changing the ride height.
- Aids with adjusting the corner-weights.
- Available in both series: Heavy-Duty and Extreme-Duty.
