ARB’s line of side rails, side steps and rock sliders will help reduce this damage, while at the same time improve access to your truck. The manufacturing process utilizes steel tube formed into shape using an internal mandrel bender, ensuring consistency and even wall thickness across all sections. This is then securely fastened to the vehicle's chassis, and with the exception of rock sliders, an integrated step system attaches to these to complete the assembly. SIDE RAILS AND STEPS A complete ARB side rail & integrated step system provides the ultimate protection for off road driving, as well as allowing for easier access to your 4x4 through the fitting of tread plate steps featured on most models. PROTECTION STEPS ARB protection steps offer your 4x4 similar benefits to conventional side steps, such as improved vehicle access and a reduction in stone chips caused by road debris. Unlike most other brands of steps, they act as a structurally sound barrier between your vehicle and rock ledges encountered in off road driving, and are far less likely to sustain damage. ROCK SLIDERS + Designed specifically for the Jeep Wrangler and FJ Cruiser, ARB rock sliders are built with high quality steel for optimal strength.
