Description

This is a vehicle-specific anti-sway bar designed to improve handling stability and tracking, especially on curves, for motorhomes, SUVs, pickup trucks, or Sprinter vans. Made of 4140 "chromoly" steel, it is stronger and more durable than standard 1020 grade spring steel. It features polyurethane bushings, impervious to gas, oil, and ozone corrosion, more resistant to abrasion, and capable of handling heavier loads. The bar is powder-coated for extreme durability and is thicker in diameter than stock bars, increasing torsional roll stiffness by approximately 30% for every 1/8" increase in diameter, offering up to 90% more resistance to sway. Although the URL suggests Ford F-550, a specific year range could not be confirmed.
