Rock Tamers GMC Trim Plates

The Rock Tamers GMC Trim Plates (RT320) are stainless steel bowtie accessory mudflap trim plates designed specifically for GMC vehicles. These complementary trim pieces enhance the appearance of your truck while protecting the lower fascia from road debris, salt spray, and mud accumulation—critical concerns for boaters and off-road enthusiasts who expose their vehicles to harsh marine and coastal environments. Sold as a complete pair, they integrate seamlessly with factory mudflap systems on compatible GMC models.

Constructed from stainless steel, these trim plates resist corrosion from saltwater exposure, a significant advantage for coastal vehicle owners who contend with accelerated oxidation and rust formation. The material's durability ensures that trim remains intact through years of exposure to UV radiation, road salt, and washing cycles. Installation adds minimal weight at 0.55 lbs, avoiding any measurable impact on vehicle handling or payload capacity. The 20-inch length accommodates the standard GMC bowtie profile, providing full coverage across the lower trim area where mud and debris typically accumulate.

These trim plates are suited for GMC truck owners who prioritize both aesthetics and functional protection. Boaters who trailer their vehicles to coastal launches benefit from the corrosion resistance, while off-road users appreciate the added defense against trail debris. The stainless steel finish maintains its appearance without regular polishing, reducing maintenance overhead compared to painted alternatives. Made in the U.S.A., the RT320 represents a straightforward, cost-effective upgrade for owners seeking to protect their investment and extend the service life of their truck's lower body panels.
