Bolder All-Terrain Capabilities. Upgrade your Trail Boss for better ground clearance and reinforced off-road performance while maintaining smooth on-road ride quality. This Rough Country 4-Inch Suspension Lift Kit with Adjustable Vertex Coil-Overs and V2 Monotube Shocks enables you to accommodate 35x12.50 tires on your truck for enhanced performance. This suspension system is designed to perfectly fit your truck’s new design with aggressive angles and head-turning styling. This kit features heavy-duty lift knuckles, adjustable Vertex coil-overs, V2 monotube shocks, crossmembers, skid plate, rear lift blocks, and U-bolts.
Smoother and Comfortable Ride. The high-performance Vertex and V2 Shock absorbers feature a monotube design with an external reservoir for increased oil capacity and damping sensitivity. Each shock is furnished with a massive 2.50-inch diameter piston and a high-flow, 22mm chrome hardened piston rod. The zinc-plated finish with a laser-etched “RC” logo reinforces corrosion resistance and offers extra visual appeal. Additionally, the 8-stage adjustable damping system allows you to conveniently set your preference from a smooth highway ride to extreme off-roading.
Premium Components for Proper Alignment. Rough Country engineered this 4-Inch Suspension Lift System with heavy-duty crossmembers and lift knuckles. It also includes differential and sway bar brackets — all with laser-cut construction for the best possible fit on your truck. In addition, these components are reinforced by a powder-coated finish to resist corrosion and withstand harsh outdoor elements.
Aggressive Stance. The rear lift kit in this 4-Inch Suspension Lift Kit includes a pair of rear blocks and U-bolts. Using this kit raises the rear of your vehicle and prevents sagging. It also maintains your truck’s factory rake, especially useful when hauling or towing. The included brackets exhibit high strength and excellent structural rigidity. Each component is built with reliable all-terrain durability for a precise fit and long-lasting functionality.
Professional Installation Recommended. Installing this 4-Inch Suspension Lift Kit requires mechanical expertise. The components install with some drilling and trimming required. It also includes all the necessary hardware for a hassle-free process.
