Construction & Design

The Tuff Country lift kit is crafted from high-strength steel components to ensure maximum durability and resistance to wear. Each part is precision-engineered to fit seamlessly with your truck’s existing suspension system, preserving factory alignment and geometry. The SX8000 shocks feature advanced valving technology and robust construction to absorb impacts and provide a smooth, controlled ride both on and off the road.

All components undergo rigorous quality control and are finished with corrosion-resistant coatings to withstand harsh environments and extend service life. This combination of durable materials and thoughtful engineering results in a lift kit that performs reliably under heavy loads and challenging terrain.

Installation & Fitment

Installation of the Tuff Country 4.5in Arm Lift Kit requires replacing the factory shocks with the included SX8000 shocks to ensure proper suspension travel and performance. This kit is not compatible with Off-roadster models, which come with a factory lift. Additionally, trucks equipped with two-piece rear drive shafts will need to install a carrier bearing drop (part #20824) to accommodate the lift.

The lift kit is designed for direct bolt-on installation using factory mounting points, minimizing the need for modifications. Professional installation is recommended to ensure safety and optimal performance. After installation, a wheel alignment is necessary to maintain proper handling and tire wear.
