ICON 59704P-CB 2.5 Series Piggyback Shocks for 2007-2021 Toyota Tundra, Pair

ICON Vehicle Specific (V.S.) 2.5 Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. These shocks are configured specifically for each application in both length and damping tune. Like all ICON'S Shock Absorbers, V.S. 2.5 Series shocks are 100% rebuildable and 100% revalveable. For piggyback and specific remote reservoir applications, ICON'S unique use of a 6061 billet aluminum manifold a few inches below the top cap of the shock creates an internal Bump Zone that when used creates an additional 20% of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. If you are looking for a more user defined tune, consider looking into the Compression Damping Control Valve (CDCV) or the Omega Series bypass shocks. 2007-2021 TOYOTA TUNDRA SECONDARY 2.5 VS PIGGYBACK SHOCK PAIR

Upgrade your 2007-2021 Toyota Tundra with the ICON 2.5 Series Vehicle Specific piggyback shock pair, part number 59704P-CB. Designed and tuned specifically for the Tundra platform, these shocks provide controlled suspension performance during off-road driving while maintaining a smooth, composed ride on the street. Vehicle-specific lengths and damping calibrations help optimize handling, ride quality, and suspension control for demanding driving conditions.
The nitrogen-charged monotube design uses a piggyback reservoir to improve heat dissipation and help reduce shock fade during extended or aggressive use. ICON’s internal Bump Zone, created through a 6061 billet aluminum manifold positioned below the shock top cap, adds up to 20% more damping force as the shock approaches full compression. This additional control helps manage high-velocity suspension movement and reduce harsh bottom-outs. The one-piece digressive piston and application-specific valving deliver predictable performance across varied terrain.
Built for long-term serviceability, the ICON 59704P-CB shocks feature a CAD-plated 1026 DOM steel body, chrome-plated induction-hardened shock shafts, premium 5WT shock oil, PTFE-lined spherical bearings, and CNC-machined 6061 aircraft-grade aluminum components. The shocks are fully rebuildable and revalveable, allowing future maintenance or damping adjustments as your vehicle setup and driving needs change. Piggyback and remote reservoir ICON 2.5 Series shocks can also be upgraded with the available Compression Damping Control Valve (CDCV) for more user-defined tuning.
