  • Improves Handling & Stability: 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
  • 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 (a 1020 grade) 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
  • Vehicle Compatibility: Fits 2006-2019 F53 & F550 Class A; Rear sway bar AUX 1 1/2 inch for coaches between 18,001-21,999 lbs GVW with shock mounts with two holes and parallel to the ground; No Thor Outlaw; Chassis model year may vary from RV model year
