ICON 01-16 GM HD 6-8in Rear 2.5 Series Shocks VS PB - Pair

ICON is known for making serious suspension components for trucks and Jeeps, and their 2.5 Series shocks are a popular choice for folks looking to improve their vehicle's handling both on and off the pavement. This particular pair, part number 77727P, is built for the rear of 2001 and newer GM HD trucks that have been lifted between 6 and 8 inches. They're designed to give you a smoother ride around town while also providing the control you need when you hit the trails.

What sets these shocks apart is their vehicle-specific tuning and construction. ICON uses a one-piece impact-extruded aluminum cylinder, which helps with corrosion resistance and keeps things looking good. Inside, a one-piece digressive piston is valved specifically for these GM HD trucks, meaning it's set up to work best with your suspension geometry. The piggyback reservoir design helps dissipate heat, reducing shock fade during long stretches of rough terrain or high-speed driving. Plus, ICON's internal “Bump Zone” adds about 20% more damping force as the shock nears full compression, helping to prevent harsh bottom-outs and keep your suspension controlled when it's working hard.

These shocks are also fully rebuildable and revalveable, meaning you can service them down the road to keep them performing like new. They use a nitrogen-charged monotube design and come with application-specific mounting hardware, including PTFE-lined spherical bearings for smooth movement. Installation is designed to be a bolt-on affair, with no cutting or welding required. This pair is built for a range of GM HD trucks, including models like the Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD, giving you a solid upgrade for your lifted rig.
