Features
The Roadmaster 1139-178 Sway Bar Kit is an excellent solution to poor handling. Adding a set of custom anti-sway bars to your suspension system results in an immediate improvement in handling stability and tracking, especially on the curves.
What was beyond your control just yesterday, is suddenly within it – cornering with confidence, quicker maneuvering, and a remarkably level ride over uneven terrain, all without launching the dishes out of the cupboard. Even after eight or 10 hours at the wheel you arrive fresh, instead of fatigued, which means you can start enjoying the Grand Canyon, the Grand Tetons, or the grandkids right away.
Bigger is Better – RSS 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% with every 1/8" increase in diameter.
High-Grade Alloy – RSS anti-sway bars are made of 4140 "chromoly" steel (a chrome and molybdenum alloy) which is considerably stronger and more durable than the standard spring steel used in many stock anti-sway bars.
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.
Baked-on Finish – Every anti-sway bar is powder-coated. In this process, charged particles of pigment are baked into the surface of the sway bar. They fuse to the metal to form an extremely durable finish.
• High-grade alloy 4140 Cromoly steel
• Polyurethane bushings
• Thicker diameter reduces sway
• Baked-on powder-coat for great looks and superior protection
