About Manufacturer

MADNESS Autoworks is your One Stop Shop for customizing, accessorizing and servicing your favorite ride.

After spending over a decade customizing countless vehicles and working with many local and international suppliers we have been fortunate to be able to offer a very large inventory of products to our fellow enthusiasts. However, at times we have found that what was available was not good enough or perhaps other options were also needed. When this happens we either design and manufacture the product ourselves or tap one of our manufacturing partners and ask them to assist and make a product to our specs.

Over the years that we have been in business we have formed a number of partnerships with our most trusted manufacturing partners and suppliers to help us produce products that we felt were needed and not available. At times we have also invested in infrastructure, manufacturing equipment and have recruiting some of the best talent that could help us design and build superior products and make them available to our fellow drivers.

Our goal at MADNESS is to provide top quality products that has been tested and used in our own vehicles and have proven to last and provide a good value for the investment. We do not design and build our products to be the cheapest, we design then to be the best value for the money and stand behind them the same way we stand behind our work.
