Bushing damage generally occurs over time due to wear and tear. Frame damage can result from rust, extreme flexing, or breakage from a forceful impact or collision.

There are three primary types of damage to a control arm: frame damage, bushing damage, and ball joint damage. Vehicles regularly driven in a harsh manner or on unpaved surfaces will have a more rapid decline in control arm function, which could negatively impact handling, comfort, and safety. Much of this wear is dependent on the type of driving that occurs over the life of a vehicle. The control arm is engineered to take on a great deal of stress and impact, but it is ultimately a wear-and-tear component with a limited lifespan. Some cars with independent rear suspensions may have control arms at the rear wheels, but this is not a typical setup. Vehicles with MacPherson-type suspension systems will only have a lower control arm, and a strut will replace the upper arm. However, there are exceptions to having a conventional upper/lower control arm layout. This architecture makes for a more substantial assembly, ensuring balanced wheel control and stability. Many vehicles have an upper and a lower control arm for each front wheel, connecting to the highest and lowest steering knuckle points. The ball joint allows the steering knuckle to pivot and gives the wheels the ability to turn while the vehicle is in motion. The bushings also reduce overall noise, vibration, and harshness (NVH) while making the vehicle's ride quality softer and more comfortable.Īt the steering knuckle end, the control arm connects via ball joint to allow smooth wheel movement in all directions. These bushings guard against metal-on-metal contact when the arm is moving up and down with the wheels. These components have connection points at each end for attaching a wheel's steering knuckle to the vehicle frame.Īt the frame or body, the control arm connects to a hinge by bolts and bushings. Cast aluminum control arms are intended for lighter weight applications.Ĭontrol arms are typically A-shaped, L-shaped, or wishbone-shaped, but designs differ from vehicle-to-vehicle based on suspension geometry. Steel and iron control arms deliver strength, sturdiness, and the ability to resist damage. They are comprised of either stamped steel, cast iron, or cast aluminum as their primary material. For this price you can’t find a better quality tubular control arm.Found on virtually all road-going suspension systems, control arms are located at the front axle at each of the two front wheels.

Performance ball joints featuring forged housings, full spherical pins and CV style dust boots are then installed and custom free moving spherical bearing mount sway bar end links wrap up the lower arms. Both upper and lowers receive non wearing greasable Delrin bushings, urethane bump stops, and grade 8 hardware. This allows two different base camber settings during alignment. The upper arms are assembled with strong and corrosion free 304 stainless steel cross shafts that feature a special offset machining process. All plate components are laser cut and CNC formed for exact tolerances, TIG welded to the tubing, and then the assemblies are powder coated gloss black.

120 wall while lowers are 1.50″ diameter. Uppers are constructed of 1.25″ diameter. But those aren’t the only benefits, read on for all the features of these great control arms.ĬAD designed tubular Control Arms are constructed from CNC mandrel bent DOM tubing. Our tubular control arms do just that, ball joint pivot points have been relocated to increase caster, promote more stability at speed, and aid in increasing camber gain. The first step to upgrading your suspension is changing the factory geometry to be more friendly to blasting curves.

Now the number of Pro Touring builds has increased exponentially over the last decade, why wouldn’t it when you find your car can move quick in a straight line and handle the curves at the end of the road. In the middle of the prime of the Pro Street movement in the 1990’s a few guys were pushing their cars towards better handling and the Pro Touring segment was born. For years we’ve all been driving our muscle cars the way they were designed, with lots of power and usually in a straight line.
