ADDCO is primarily a performance company that provides aftermarket and OEM products to the performance auto industry. They design and manufacture tubular and solid sway bars (swaybars), also known as anti-sway bars. ADDCO was one of the first companies to use polymers in their stabilizer bushings. ADDCO makes solid sway bars to a diameter of 2 1/8" and tubular bars to 3"

Anti-sway bars are intended to limit body roll and keep all 4 tires planted to the pavement. When the body rolls it loads the outside side of the car taking weight off the inside. This caused the front end to push and not turn. ADDCO anti-sway bars fix this problem.
