The only award winning Shield Manufactured in the U.S.A.
Our shields are designed by an actual master tech for vehicles. We have never had a single theft of catalytic converters in 4 years of business. We are trusted by Toyota, Dodge, Chevrolet and Ford dealerships, as well as, Fleets. We also have our own proprietary security bolts that come standard with the shields at no cost to the customer! We use Aluminum because it gums up a blade, on the sawzall, and becomes a melted mess on the blade and the shield. We have seen a couple tries of thieves trying to get through the shields with a sawzall and they gave up. One of our dealers who preloads new vehicles with our shields had a thief try to cut, crowbar, anything they possibly could to get the shield off. Theyt couldn't do it. The thieves got so mad they destroyed the actual truck, but it still had its CATs. We are so confident in our product that we offer 100% MONEY BACK GUARANTEE if our product fails in keeping your Catalytic Converters Safe. Trust ADD Automotive to be there for you always.
Did you lose or misplace your security bit? Did you purchase a used vehicle with the ADD A CAT Catalytic Converter Shield already installed? Or maybe you would just like to have an extra one just in case.
Here at ADD Automotive, we’ve been in the automotive catalytic converter shield business for the last 4 years. We manufacture and sell corrosion-resistant, durable Catalytic Converter Shields ADD Automotive. Our fully custom-designed product will not void your vehicle’s warranty and does not require any parts modification for installation. We also provide fully custom, American-made, proprietary security bolt fasteners when you purchase a shield. It also functions as a skid plate for your vehicle.
These are available in certain models of Toyota, Lexus, Ford, Chevy, Ram, GMC, and Isuzu. They are made of a high-grade aluminum that works to both dissipate heat and resist corrosion. The shield can end up paying for itself in the long term, as it can get you a discount on your monthly car insurance rate. In 4 years of business, no thief has been able to get through our shields to steal our customer’s converter.
