Description
Aggressive Lift and Suspension Performance. This Rough Country 3.50-Inch Knuckle Suspension Lift Kit with Adjustable Vertex Coil-Overs and Vertex Shocks equips your truck for the most rugged adventures that you can find for your vehicle. It improves steering control, clearance, and suspension articulation so you can conquer the most brutal roads with superb handling. This kit also provides an aggressive stance by leveling its front with its rear, giving your truck a more muscular and intimidating look than before.
High-Performance Vertex Shocks. The front Vertex Coil-over Shocks and rear Vertex reservoir shocks included in this lift kit come with an 8-stage damping system. It provides superb flexibility, remarkable shock damping capability, and smoother ride quality. Featuring a massive design, these shocks come with large pistons that carry more fluid than OE shocks to ensure better heat dissipation. Their monotube construction also features a 22mm chrome-hardened piston rod and a honed steel body with a 3-stage seal system to guarantee leak-free compressions. Finally, these shocks’ zinc-plated finish with a double clear coat and CNC-machined billet aluminum accents adds excellent protection against corrosion and gives your truck a more striking appeal than ever.
Premium Lifted Knuckles. The lifted knuckles included in this Lift Kit are engineered to deliver superb performance in lifted applications. They offer increased clearance, which promotes excellent upper arm ball joint angle and remarkable ride quality. These knuckles are also made from durable material for lasting strength and superior steering performance on uneven roads.
High-Quality Spacers and Blocks. This Suspension Lift Kit comes with spacers, lift blocks, and U-bolts that are made of highly durable materials. They are specially engineered to provide accurate geometry and rock-solid off-road suspension performance.
Professional Installation Recommended. This Suspension Lift Kit is equipped with components that attach to OE mounting points. However, this kit’s installation will require some disassembly and cutting. As such, AmericanTrucks highly recommends professional installation to ensure satisfaction.
Limited Lifetime Replacement Warranty. To ensure customer satisfaction, Rough Country provides a lifetime warranty for most of this Knuckle Suspension Lift Kit’s components against material or workmanship defects from the original date of retail purchase.
