Description

Juggernaut 2019+ GMC Sierra 1500 Transmission Skid Plate & Cat Shield

Transmission & Catalytic Converter Protection. Bolt-On Installation. Made in the USA.

Two of the Most Expensive Targets, Covered by One Plate

The transmission pan and catalytic converters hang low and exposed on the 2019-current Sierra 1500, right where rocks, road debris, and steep breakover angles find them first. A cracked pan means a tow and a four-figure repair; the cats are an even bigger problem, since thieves can cut them out in under two minutes in a parking lot.

Aluminum can't rust the way steel plates do — every scratch on steel armor is where corrosion starts, especially with road salt. Ours is 1/4" 5052 aluminum, powder-coated black, CNC plasma-cut and press-brake formed in our Wheat Ridge, Colorado shop.

Why Choose Juggernaut Protection?

The Pain: The transmission pan and catalytic converters hang low and exposed, right in the strike path of rocks and road debris — and cats are an easy theft target.
The Juggernaut Solution: This plate shields both — impact protection underneath and a solid deterrent between a sawzall and your converters.

Service without pulling the plate.

Powder-Coated Black

A durable black finish adds abrasion resistance on top of aluminum's natural corrosion resistance.

Bolt-on installation using factory mounting points — no holes, no modifications.

Made in the USA

Designed, cut, and finished in Colorado. Backed by a lifetime warranty.

Cat Theft Deterrent

Covering the converters makes them far harder to access and cut out.

Frequently Asked Questions

+ What does this plate protect?

The transmission pan and catalytic converters — two of the most expensive and most targeted parts under the truck.

+ Can I still change my oil?

Yes — a removable oil drain access panel lines up with the drain plug, so oil changes don't require dropping the plate.

+ Does this also fit the Chevy Silverado?

Yes — this is the same plate used on our Chevy Silverado 1500 listing, since the two trucks share the same underbody geometry.

+ Will this fit with a suspension lift?

Not with a 4"+ lift — aftermarket drop brackets and crossmembers interfere with the factory mounting points this plate uses.

+ Can I buy this as part of a package?

Yes — pair it with the Engine and Transfer Case skids, or get all three at a discount in the Sierra 1500 Skid Plate Package.

+ Does adding a skid plate void my vehicle warranty?

No — under the Magnuson-Moss Warranty Act, bolt-on aftermarket parts can't void your factory warranty on their own.

Prop 65

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
