  • Bigger is Better - Roadmaster anti-sway bars are thicker than OEM and replacement bars. Every 1/8" increase in diameter results in over 30 percent sway improvement. On average Roadmaster Anti-Sway Bars provide over 90 percent more resistance to sway
  • A High-Grade Alloy - Made from 4140 Chromoly steel (a chrome and molybdenum alloy) which is considerably stronger and more durable than standard spring steel used by most others
  • A Better Pivot Point - Polyurethane bushings are impervious to gas, oil and ozone corrosion, more resistant to abrasion, and doesn't buckle under heavier load weights. OEM and most after market bars use rubber which simply doesn't last
  • Stop Sway - Better handling, less fatigue, higher performance
  • Stops Windbuffet - Increased confidence, less fatigue
