Description

Miller CAT Anti‑Theft Cat Shield | Fits Nissan Frontier 2022–current | Ultimate Protection

The sinking feeling of starting your truck and hearing a deafening roar is one no Nissan Frontier owner should experience.

Catalytic converter theft is more than an inconvenience. It's a costly violation that can leave your truck disabled for weeks and hit you with a repair bill in the thousands. 

Thieves target the Nissan Frontier for a reason: its ground clearance provides easy access to the valuable catalytic converters underneath. They can steal them in under 60 seconds, leaving you stranded.

The MillerCat Nissan Frontier 2022+ Cat Shield is the definitive solution, providing robust, precision-engineered armor that gives you the peace of mind to park anywhere with confidence.

The MillerCat Cat Shield creates a tough, time-consuming barrier, it turns your truck from an easy target into a protected fortress.

Industry Recognized: SEMA Award-Winning Design & Engineering

Key Benefits of the MillerCat Shield

  • A Multi-Layered Defense System

    Our solution combines a thick aluminum shield with our proprietary tamper-resistant hardware. This forces thieves to not only get through the shield but also deal with fasteners they don't have the tools for. This complexity is your best defense, encouraging them to move on to an easier target.

  • Preserves Vehicle Integrity & Performance

    What is the best cat shield design? One that protects without compromise. Our extensive ventilation cutouts are computer-designed to maintain critical airflow, preventing heat from being trapped around your catalytic converter and transmission. This protects your vehicle's sensitive components and ensures long-term reliability.

  • Lightweight Yet Robust Protection

    We use premium, high-strength 5052 aluminum, the same grade trusted in aerospace and marine applications. This gives you a shield that's incredibly tough and rigid against cutting tools, yet lightweight enough that it won't affect your Frontier's fuel economy, handling, or suspension.

Frequently Asked Questions

+ Why is the Nissan Frontier a target for catalytic converter theft?

Like many trucks, the Frontier's factory ground clearance makes it easy for thieves to slide underneath quickly without a jack. Our cat shield closes this window of opportunity by creating a robust barrier that requires too much time and effort to bypass.
+ Do I need special tools for the security hardware?

The kit includes one proprietary driver bit that fits the tamper-resistant screws. This special bit is required for installation and removal, providing a crucial layer of security that standard screwdriver or socket sets do not have.
+ Will this shield cause any rattling or vibration noises?

No. The shield is precision CNC cut and formed based on a 3D scan of the Frontier's underbody, ensuring a perfect fit. When installed correctly to the factory points, it becomes a rigid part of the vehicle with no rattling or vibration.
+ Does the shield interfere with oil changes or other maintenance?

The shield is designed specifically to protect the catalytic converters and does not block access to the oil drain plug, oil filter, or transmission service points. Routine maintenance can be performed without removing the shield.
+ Can a determined thief still cut through the aluminum?

No security device is 100% theft-proof. The goal of a cat shield is deterrence. Our thick aluminum shield makes cutting extremely loud, difficult, and time-consuming. This added time and noise dramatically increases the thief's risk of being caught, which is why they will almost always move on to an unprotected vehicle.

California Residents

Prop 65 Warning- Product may contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov

Proposition 65 is a California law passed in 1986. Its goals are to protect drinking water sources from toxic substances that may cause cancer and birth defects and to reduce or eliminate exposures to those chemicals generally, for example in consumer products, by requiring warnings in advance of those exposures.

The regulation requires the State of California to revise and republish yearly a list of chemicals known to the State of California to cause cancer or birth defects or other reproductive harm. The current list contains over 900 naturally occurring and synthetic chemicals. This regulation also requires manufacturers to place warnings on products that contain any of the chemicals listed by the State of California. No other states require warnings of this nature, and products with Prop 65 warning language are legal to sell in all states. Detailed information regarding requirements for compliance to the California Prop. 65 is can be found at: www.P65Warning.ca.gov

Solid and waterproof tent!

We have been on multiple trips with this tent. Its stable and comfortable with a good space for 2+ person to sleep in. Easy to setup and can be taken down under 10 minutes. The tent is waterproof and windproof and can be used during the winter season. Its worth the money and we are overall satisfied with our tent.

Love it!

Looks great and very easy to install. Fits perfectly with no cutting on my Colorado 5 1/2 ft bed. As I unfolded the cover for the first time and each panel locked in place perfectly, I thought, Wow, that was easy.
