Adjustable Rear Lower Control Arms
The easy adjustment of MM's Adjustable Control Arms allows raising the rear ride height by up to 2 inches, or lowering it as much as 1 inch. A heavy-duty weight-jack bolt, similar to those used in NASCAR, makes this possible. The spring perch design allows easy ride height changes, with the car still on the ground. Road racers and autocrossers can set not only the ride height, but also corner weights, for optimum handling. A car can be fully loaded up with gear for a road trip, and then have the rear ride height adjusted back up to normal, to avoid bottoming out. These control arms are available with mounts for a factory-style rear swaybar, or without any swaybar mounts, for use with MM's Adjustable Rear Swaybar.
Urethane Bushings
The MM Heavy-Duty Rear Lower Control Arms utilize specially designed 3-piece urethane bushings at the chassis end. These bushings have a hard center section to prevent fore and aft deflection, and softer outer sections to allow the angular motion necessary to prevent bind. This design, with softer outer urethane sections, prevents torque-box damage due to binding of the lower control arms. At the axle end, they use a high quality Teflon-lined spherical bearing to precisely locate the rear axle. Unlike the other bushing types listed above, a spherical bearing allows freedom of motion for both pivoting and angularity. As with the 3-piece urethane bushings, this freedom of motion improves handling over other styles of bushings, and prevents damage to chassis components.
MM places the 3-piece urethane bushing at the chassis end, rather than at the axle end, for two reasons. First, this reduces the amount of noise, vibration, and harshness (NVH) that is transmitted into the chassis. Second, because the spring is mounted to the control arm and the chassis, it is best to keep the control arm and chassis from getting too far out of line with each other. If the spherical bearing is placed at the chassis end of the control arm and the urethane at the axle end, the control arm will tend to stay in alignment with the axle. This would cause the spring to arc sideways with body roll, and change the effective wheel rate.

Product Note
The Adjustability Range Is .90" Below And 2.00" Above The Point At Which The Rear Springs Lower Your Mustang. Bushing Lubrication
- The suspension bushings included with this part can only be lubricated with PTFE grease, also referred to as "Marine Grease". PTFE grease is a very sticky, opaque grease that is water proof and will not degrade the bushing material. If lubed properly at installation, these bushings will not need to be lubricated again. Use of any other grease on these bushings will cause the bushing to fail and any bushing warranty to be voided.
- If these control arms will be installed on an early model Fox Body Mustang with the small rear sway bar, you must transfer over the factory sway bar bracket and attach it to the bracket on the new lower controls or upgrade to a larger sway bar.
- Due to the use of spherical bushings within this product, you will experience an increase in noise, vibration, and harshness.
