What is ICON's "Bump Zone" technology?

ICON's internal "Bump Zone" is a design feature within the piggyback reservoir manifold. It's engineered to increase damping force by 20% as the shock absorber approaches its full compression point. This helps prevent harsh impacts when bottoming out and offers better control during rapid suspension compression.

Are these shocks compatible with a lifted truck?

Yes, these rear shocks are specifically designed for 0-2 inches of rear lift on the 2019+ GM 1500 platform. They are configured in both length and damping tune to work with this lift range.

What does it mean that these shocks are rebuildable and revalveable?

Rebuildable means you can disassemble the shock to replace worn internal components like seals and O-rings, extending the life of the shock. Revalveable means you can change the internal valving shims to alter how the shock responds to different terrain or driving conditions, allowing for custom tuning.

Product Details

The 6061 aircraft grade aluminum construction of these ICON 2.5 Series rear shocks is a solid starting point for improving your 2019-2023 Chevrolet Silverado 1500's suspension. These shocks are built with a nitrogen-charged monotube design and feature a piggyback reservoir, which helps dissipate heat and reduce shock fade during extended use, especially off-road. ICON specifically tunes the valving for your truck, aiming for a balance of outstanding off-road performance and a comfortable street ride.

A notable feature is ICON's internal "Bump Zone." This design choice, integrated into the piggyback reservoir manifold, effectively increases damping force by 20% as the shock nears full compression. This helps prevent harsh bottom-outs and provides better control when the suspension is compressing rapidly. The one-piece digressive piston design further contributes to this tailored performance, ensuring the shocks react appropriately to varying terrain. These shocks are also 100% rebuildable and revalveable, meaning you can service them and adjust their tuning to your preferences over time.

Included with these rear shocks are PTFE lined spherical bearings and application-specific mounting hardware, ensuring a direct fit for your Silverado 1500 or Sierra 1500. The one-piece impact extruded aluminum cylinders offer good corrosion resistance, and the premium 5WT shock oil is chosen for consistent damping across a wide temperature range. If you're looking to lift your truck between 0 and 2 inches, these shocks are designed to work with that setup.
