ROADMASTER ANTI-SWAY BARS ARE BUILT TO OFFER SIGNIFICANTLY MORE RESISTANCE TO SWAY THAN STOCK BARS.

Bigger is better - Roadmaster anti-sway bars have a thicker diameter than stock bars (often, a quarter to three-eighths of an inch more). Each incremental increase in diameter has an exponential effect on performance - on average, torsional roll stiffness is increased by 30 percent with every eighth-of-an-inch increase in diameter. In plain English, RSS anti-sway bars offer up to 90 percent more resistance to sway.

A high-grade alloy - RSS anti-sway bars are made of 4140 "chomoly" steel (a chrome and molybdenum alloy) which is considerably stronger and more durable than the standard spring steel (a 1020 grade) used in many stock anti-sway bars.

A better pivot point - RSS anti-sway bars have polyurethane bushings, which, unlike the rubber used in stock bushings, is impervious to gas, oil and ozone corrosion, is more resistant to abrasion, and doesn't buckle under heavier load weights.

EACH KIT COMES COMPLETE WITH HEAVY-GAUGE MOUNTING HARDWARE, EASY-TO-FOLLOW INSTRUCTIONS, AND THE BUSHING LUBRICANT.
