Description

Roadmaster anti-sway bars are engineered to enhance vehicle stability and cornering performance, particularly for heavy-duty applications like RVs, SUVs, pickup trucks, and Sprinter vans. They are designed to mitigate body roll and sway caused by external factors such as wind, passing vehicles, and uneven road surfaces. Key product attributes include: Thicker Diameter: Compared to original equipment (OE) bars, Roadmaster anti-sway bars feature a thicker diameter. This design choice significantly increases torsional roll stiffness—approximately 30% for every 1/8-inch increase in diameter—leading to up to 90% greater resistance to body sway. High-Grade Alloy Construction: The sway bars are manufactured from 4140 "chromoly" steel, an alloy of chrome and molybdenum. This material is chosen for its superior strength and durability compared to the standard 1020-grade spring steel often used in stock anti-sway bars. Polyurethane Bushings: The pivot points utilize polyurethane bushings, which offer several advantages over traditional rubber bushings. Polyurethane is resistant to degradation from gas, oil, and ozone corrosion, exhibits greater abrasion resistance, and maintains structural integrity under heavy loads. Durable Powder-Coated Finish: Each anti-sway bar is treated with a baked-on powder coating. This process applies charged pigment particles to the metal surface, which then fuses during baking to create an extremely durable and protective finish. American Manufacturing: Roadmaster emphasizes that its products are "Made in the USA," handcrafted by American workers, and built to withstand rigorous use, reflecting over 50 years of manufacturing experience.
