ICON 57721CP-CB 2.5 VS Piggyback CDCV Rear Shocks for 2007-2021 Toyota Tundra with 6-Inch Lift, Pair

ICON Vehicle Specific (V.S.) 2.5 Aluminum 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 Aluminum 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. The ICON CDC Valve is an externally adjustable valve that restricts oil flow into the reservoir which creates 10 levels of compression damping force ranges. If you are looking for a more user defined tune, consider looking into the Omega Series bypass shocks. 2007-2021 TUNDRA 6" LIFT REAR 2.5 VS PIGGYBACK CDCV SHOCK PAIR

• One piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road

• One-piece impact extruded aluminum cylinders offer excellent corrosion resistance and consistent finish
• Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range
• Remote reservoir design improves heat dissipation to reduce shock fade during prolonged use
• PTFE lined spherical bearings and application specific mounting hardware
• 7/8” diameter induction hardened, chrome plated shock shaft
• Nitrogen charged monotube design with piggyback reservoir
• 6061 aircraft grade aluminum CNC machined components
• 100% Revalveable
• 100% Rebuildable

ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks are engineered for the 2007-2021 Toyota Tundra with a 6-inch lift, delivering controlled off-road performance and a comfortable street ride. This pair of rear shocks uses vehicle-specific length and damping calibration to match the application. The nitrogen-charged monotube design, piggyback reservoir, and remote reservoir-style architecture improve heat dissipation, helping reduce shock fade during extended or demanding use. The ICON 57721CP-CB shocks are also 100% rebuildable and revalveable for long-term serviceability and tuning flexibility.
The integrated ICON CDC Valve provides 10 levels of high-resolution compression adjustment through an easily accessible control knob. This allows drivers to fine-tune damping for changing terrain, load conditions, and driving preferences. ICON’s internal Bump Zone is created by a 6061 billet aluminum manifold positioned below the shock top cap. When engaged during high-velocity compression, it adds approximately 20% more damping force to help control suspension movement and reduce harsh bottom-outs.
Each shock features a one-piece digressive piston with application-specific valving, a durable impact-extruded aluminum cylinder, and premium 5WT shock oil for consistent damping across a broad temperature range. PTFE-lined spherical bearings and application-specific mounting hardware support precise suspension movement and secure installation. The 7/8-inch induction-hardened, chrome-plated shaft provides strength and durability, while CNC-machined 6061 aircraft-grade aluminum components offer corrosion resistance and a consistent finish. This rear shock pair is designed for lifted Tundra applications and is intended for enthusiasts seeking adjustable, rebuildable suspension performance.
