Description
Balanced 6-Inch Lift with Restored Geometry. This Tuff Country Six-Inch Suspension Lift raises the front and rear by six inches using forged control arms up front and four-inch blocks in back, restoring proper suspension angles and ride height. The monotube shocks matched to the lift height deliver consistent damping over rough terrain and loaded hauling, while the extended brake lines and track bar drop bracket maintain full wheel articulation.
Durable Components for Heavy-Duty Use. Forged steel control arms resist bending under load, and the heavy-duty blocks and U-bolts secure the rear assembly against shifting. Powder-coated finishes protect metal parts from corrosion, ensuring long-term reliability even in harsh conditions.
Installation. This product bolts to factory suspension and frame mounts with supplied hardware—no cutting or welding required.
Application. This Tuff Country Six-Inch Suspension Lift Kit fits 2011–2019 Four-Wheel-Drive Sierra 3500 HD Models.
