ICON Stage 2 0-2 inches Lift Suspension System for 2011–2019 GM 2500/3500 HD

Part Number: K78102

Summary: The ICON Stage 2 suspension system provides a 0-2 inches lift height designed specifically to optimize the ride quality of 2011–2019 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks. This system features V.S. 2.5 Series Piggyback shocks and Tubular Delta Joint Upper Control Arms to overcome the harshness typically associated with heavy-duty torsion bar front ends. By integrating the high-articulation Delta Joint, this stage achieves a significant 2 inches increase in wheel travel over the OEM configuration while maintaining full towing capacity.

Features

• V.S. 2.5 Series Shocks: Vehicle-specific tuned 2.5 inches diameter shocks provide superior damping and control to ensure optimum ride quality on and off-road.
• Delta Joint Technology: The patented Delta Joint provides high-angle articulation with the durability of a sealed ball joint to ensure long-term reliability and increased wheel travel.
• Piggyback Reservoirs: External reservoirs increase oil volume and surface area to provide cooler operating temperatures and consistent damping during heavy use.
• Increased Wheel Travel: Optimized suspension geometry provides a 2 inches increase in wheel travel over stock to ensure better performance on uneven terrain.
• System Durability: 6061 aircraft-grade aluminum CNC machined components and one-piece impact-extruded aluminum cylinders provide excellent corrosion resistance to ensure a consistent finish and longevity.
• Installation: A 100% bolt-on design provides a straightforward fitment process with no drilling, cutting, or welding required to ensure a factory-clean install.
