OEM Control Arms vs. SSM Control Arms

Many older muscle cars (such as Ford Fox-bodies and GM A-bodies/G-bodies ) have rear suspension systems that use control arms or trailing arms to secure the rear end axle housing to the vehicle. These control arms are basically designed to perform one simple function, to hold the rear axle housing in place, under your car. There are two upper-arms and two lower-arms attached to the axle housing, and also to the body of your car. They will flex and twist to allow for a soft, comfortable, smooth, and forgiving ride for your daily street driving. The axle housing can only move sideways a very small amount, but can move freely move up and down with the shocks and springs.
These OEM trailing arms or control arms are made from very thin stamped steel formed into a U-shape with only three sides. They have soft rubber bushings pressed inside the ends, at their attachment points to your vehicle. These soft bushings will compress and absorb body roll and chassis flex as you drive which guarantees that you and your passengers are getting a nice smooth ride even on rough roads.
This type of OEM control arm/trailing arm will not work under the hard accelerations and high RPM launches demanded in performance-handling. They will flex, bend, twist and distort under the pressure. This then will allow the rear axle to move around side-to-side and up and down because of its thin-steel, three-sided design with soft rubber OEM bushings. All of these different movements of the control arms cause the rear axle housing to shift left and right and bounce around, breaking tire traction and creating “Wheel-Hop”. This of course, causes your precious HP and torque to go up in smoke. Tire Smoke! These OEM trailing arms and control arms are just NOT strong enough for performance demands.

They have the control arms available to solve your OEM traction issues. Southside Machine (SSM) products will meet your performance demands with their engineered heavy-duty rear upper control arms.
