Catalytic Converter Shields for Toyota, Lexus, Ford, Dodge/Ram, Chevrolet, GMC, Isuzu

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.

You can order online or call ADD Automotive for a quote at 281-608-2894. We can send them to you anywhere in the United States. Installing the shield should take you less than 30 minutes. Just place the adhesive rubber bumper in a suitable location and tighten the security bolts.

You can stop in to have them installed at our Kingwood, Texas location any day from 7:30 a.m. to 5 p.m. or at our Downtown Houston location Monday to Friday from 8 a.m. to 2 p.m. Please make an appointment before visiting either location.

Insurance Discounts

Did you realize that once you purchase a shield and get it installed you can take your receipt of your purchase to your insurance company and receive a discount on your auto insurance? Make sure to tell the insurance company you now have a shield protecting your converters and they will give you that discount.

We offer protectors for many models from 2003 to 2025. Contact us today at 281-608-2894 to get a quote.
