Icon Vehicle Dynamics 77703P 2.5 VS PB Rear Reservoir Shock Lift 0-2" Chevrolet Silverado/GMC Sierra 1500 19-26 Pair

ICON Vehicle Specific (V.S.) 2.5 Aluminum Series Shocks

ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks are engineered to deliver excellent off-road performance while maintaining a smooth on-road ride. Each shock is configured for the specific vehicle application in both length and damping tune. Piggyback and remote reservoir designs incorporate a 6061 billet aluminum manifold to create an internal “Bump Zone” that increases damping and helps prevent harsh bottom outs under high-velocity compression. These shocks are fully rebuildable and revalveable, with optional compression-adjustable models available.

Key Features

• Internal "Bump Zone": increases damping by 20% to provide added control as the shock approaches full compression
• Remote reservoir design: improves heat dissipation to reduce shock fade during prolonged use
• Premium 5WT shock oil: ensures consistent damping across a wide temperature range
• Nitrogen-charged monotube: monotube design with piggyback reservoir for reliable performance
• One-piece digressive piston: vehicle-specific valving for superior performance and ride quality on and off-road
• 7/8" induction-hardened, chrome-plated shaft: durable shock shaft construction
• PTFE-lined spherical bearings: with application-specific mounting hardware
• 6061 aircraft-grade aluminum CNC components: precision-machined parts for strength and consistency
• One-piece impact-extruded aluminum cylinders: excellent corrosion resistance and consistent finish
• Upgradeable: 2.5 Aluminum Series piggyback reservoir shocks can be upgraded with ICON compression adjusters (CDCV, CDXS, or CDEV)
• 100% Rebuildable
• 100% Revalveable
