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. 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 TUNDRA 6" LIFT REAR 2.5 PIGGYBACK SHOCK PAIR
  • All ICON 2.5 Series Piggyback and Remote Reservoir shocks can be upgraded to ICON’s Compression Damping Control Valve (CDCV)
  • One piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road
  • ICON’s internal “Bump Zone” increases damping by 20% to provide more control as the shock approaches full compression
  • 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% Rebuildable
  • 100% Revalveable

Upgrade the suspension performance of your lifted Toyota Tundra with the ICON 57721P-CB 2.5 Aluminum Series piggyback rear shocks. Designed specifically for 2007-2021 Tundra models equipped with a 6-inch lift, this matched pair uses application-specific shock length and damping to deliver controlled handling off-road while maintaining a smooth, composed ride on pavement. The nitrogen-charged monotube design and piggyback reservoirs help manage heat during extended or demanding driving conditions, reducing shock fade and maintaining consistent performance.
Each ICON 2.5 Series shock features a one-piece digressive piston with vehicle-specific valving for balanced ride quality and suspension control. ICON’s internal Bump Zone increases damping by approximately 20% as the shock approaches full compression, helping control high-velocity suspension movement and reduce harsh bottoming. One-piece impact-extruded aluminum cylinders provide corrosion resistance and a consistent finish, while premium 5WT shock oil supports reliable damping across a broad range of operating temperatures.
The ICON 57721P-CB shocks are built for long-term service and future tuning. PTFE-lined spherical bearings, application-specific mounting hardware, a 7/8-inch induction-hardened chrome-plated shaft, and CNC-machined 6061 aircraft-grade aluminum components provide durability in demanding environments. The shocks are fully rebuildable and revalveable, and they can be upgraded to ICON’s Compression Damping Control Valve for additional user-adjustable tuning. This rear shock pair is an appropriate choice for Tundra owners seeking improved suspension control, durability, and off-road capability after installing a 6-inch lift.
