Product Description

Upgrade your trailer with this heavy-duty molded plastic step fender engineered for durability and a clean, professional look. Designed to fit 8"–12" trailer tires, this fender measures 21.8" long, 7.1" wide, and 6.4" high, making it ideal for small utility, boat, jet ski, and cargo trailers. The high-strength HDPE construction is lightweight yet impact-resistant, offering long-lasting protection against water, sun exposure, and road debris. The UV-stable silver finish, made with Silver Polyethylene, maintains its color and resists fading over time. A reinforced, ribbed step surface adds convenience for light foot use when the fender is properly supported and mounted, while the molded arch and integrated backing skirt help shield your trailer and cargo from splash, dirt, and gravel. Built in the USA to dependable manufacturing standards, this fender provides reliable performance and an easy bolt-on installation using standard trailer hardware or brackets (not included).
