Construction & Design

Tuff Country’s 6-inch lift kit is constructed with high-strength steel components that are precision-engineered for durability and reliability. The coil springs are designed to handle increased suspension travel without binding, a common issue with lesser kits. The tubular low-profile radius arms included in the performance version are fabricated to maintain the factory suspension geometry, which preserves handling characteristics and prevents premature wear on suspension components.

The SX8000 shocks feature advanced valving technology to deliver consistent damping performance across a variety of terrains, ensuring your Ram maintains composure whether cruising highways or tackling off-road trails. Every component is finished with corrosion-resistant coatings to withstand harsh environments and extend the life of your lift kit.

The kit is available in two configurations: a standard version that includes radius arm drop brackets and a performance version featuring replacement tubular radius arms for enhanced suspension geometry and ride quality.
