ADDCO Manufacturing Company, Inc. produces the world’s broadest line of automotive anti-sway bars and associated components. In addition to being the recognized leader in aftermarket suspension parts, we are a proven, high quality provider to the OEM market, offering the responsive and cost-effective service that only a lean, flexible, state-of-the-art manufacturer can provide.

ADDCO was started in 1961, utilizing American craftsmen to provide performance products that no one else was making at the time.

Having won numerous SEMA design awards since, this tradition has continued.

Now based in South Florida, we have introduced cutting edge CNC technology and advanced production management.  The machinery and methods that we use to produce the bars may have changed.  But, the people making them are, at the core, the same.
