Installing CPP stamped steel control arms lead image

Have you ever been on the floor of your garage with your old car on jack stands? If so, you’ve probably noticed a few problem areas. It seems that 50-plus years of service can take a toll on certain components. Your factory stamped steel control arms are no exception. It was the same with our 1964 Chevelle project car; we had some serious wear. So we began disassembling the car to swap the original drum brakes for a Classic Performance Products (CPP) disc brake system.

Suspension upgrades and installs are typically a “can of worms” because you’ll eventually replace every component under the car by the time you reach a stopping point. Such is the case with our Chevelle four-door sedan, as we noticed severe ball joint sloppiness and lots of crumbly, dry rubber where the control arm bushings are supposed to live. It would’ve been silly to reassemble the car with those ailing components beneath it, so we grabbed our favorite screwdriver and peeled open the can of worms.

Why Use CPP Stamped Steel Control Arms?

Ball joint replacement can be a pain, no matter how many times you perform the task. Endless grinding, chiseling, and cutting the rivets that hold the upper ball joint in place. Even the control arm bushings call for a lot of patience. It usually requires an air chisel to remove them and a hydraulic press to install the new bushings. Then, by the time we paid for the ball joints and bushings, and then spent the time disassembling and installing the new parts, we would be way ahead of the game by simply buying new control arm assemblies. You know, stamped steel control arm assemblies that are already loaded up and ready to bolt into place.

CPP offers new control arm assemblies for many makes and models, including our early GM A-body. Installation is still labor intensive. The tight fitment of the lower control arms requires special care. And. what’s more, the splined upper control arm bolts can cause a headache if not properly removed. But, for the money and the time invested, we were very happy with the complete assembly.

For our build we wanted something that was budget-friendly and mild-mannered. Because of that we went with the stamped steel control arms with rubber bushings. Of course, CPP also offers tubular control arms with billet cross shafts and self-lubricating plastic bushings that are guaranteed not to squeak.

Install Tech Tips

Installing the control arms requires some simple hand tools. But, you can make life a lot easier by using a 1/2 inch impact with some 11/16- and 3/4-inch sockets. You’ll need a floor jack, a few blocks of wood, a good rubber mallet, and some grease to lubricate the bushings. After the new control arms are installed and the rest of the front suspension and steering system is completed, we’ll have the suspension aligned. Then, it’ll be time to enjoy the tight feeling of a brand-new front suspension. Safety, comfort, and longevity is what we strive for with our 1964 Chevelle project. CPP control arms saved a lot of time to get us one step closer to that goal and being on the road again.
