Description

Juggernaut 2020-current GMC Sierra 2500HD/3500HD Transmission Skid Plate & Cat Shield

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

Two Vulnerable Targets, One Plate

This plate shields both the transmission pan and the catalytic converter — two of the most expensive, most exposed components hanging beneath the 2020-current Sierra 2500HD and 3500HD. A cracked transmission pan means a fluid leak and a tow; a stolen or damaged catalytic converter is a repair bill that runs into the thousands.

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: An exposed transmission pan and catalytic converter are two of the costliest things to damage or lose on the trail or in a parking lot.
The Juggernaut Solution: One plate that shields both, backed by a full 1/4" aluminum construction on 3/16" steel brackets.

Dual Protection

Helps Deter Cat Theft

Adds a physical barrier that slows down would-be catalytic converter thieves.

Full 1/4" Aluminum Plate

Lighter than steel and immune to the rust that eats away at steel armor over time.

3/16" Steel Mounting Brackets

Heavy-duty brackets hold the plate firmly to factory mounting points.

No Drilling Required

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

Gas & Diesel Compatible

Made in the USA

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

Frequently Asked Questions

+ What does this plate protect?

Both the transmission pan and the catalytic converter.

+ Does this really help with catalytic converter theft?

It adds a physical barrier over the converter that slows thieves down significantly — no shield can guarantee prevention, but it's a meaningful deterrent.

+ Does this fit my Chevy Silverado HD too?

This specific listing is for the GMC Sierra 2500HD/3500HD — we use the same plate on our Chevy Silverado 2500HD/3500HD listing, so check that listing if you drive a Silverado.

+ 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.

+ 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
