The SYT4000 Poly Fender is manufactured using a proprietary material and thermoformed using proprietary technology. Designed with a unique outer lip, SYT fenders provide superior control of spray and debris off the tires. That means clean, damage-free freight and a safer environment for you and other drivers on the road. When dented or crushed they bounce back into shape. The material is extremely durable, impervious to salt and corrosion, and can withstand temperatures ranging from -100º F to 197º F.
SYT never stops innovating. They go head-to-head with shiny metal fenders that bend and break. You get the remarkable shine and reflection of a metal fender combined with the durability and advantages of the standard SYT Poly Fenders. SYT fenders are also offered in a unique carbon fiber look! This new look adds a distinctive style to any truck and trailer.
