Description Shipping information Reviews

Two-shock front pair for 2.5-inch lift on the 2018–2023 Jeep Wrangler JL or 2020–2023 Jeep Gladiator JT. These front shocks use remote reservoirs. For a JT Mojave application, confirm the supporting ICON 611070 front misalignment spacer kit before installation; it is not included with these shock pairs. These are replacement shock pairs, not a lift kit or a complete four-shock set.

Fixed Damping is not externally adjustable. Manual CDCV uses a knob with 10 levels of compression adjustment. Electronic CDEV uses ICON Intelligent Control (IIC). The CDEV option requires a compatible IIC installation kit, part 23502, sold separately. If your vehicle already has a compatible IIC system, do not buy a duplicate controller kit. Fixed and manual CDCV options do not require IIC.

Supplier-listed service parts and add-on accessories are separate purchases unless expressly listed as included. Exact variant applications are shown below; coverage differs between some configurations.

Fixed Damping · 27821P

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 Percent rebuildable and 100 Percent 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 Percent 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) shocks.

Features and Benefits:

  • ICON's internal InchBump Zone Inch increases damping by 20 Percent to provide more control as the shock approaches full compression
  • Remote reservoir design improves heat dissipation to reduce shock fade during prolonged use
  • Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range
  • Nitrogen charged monotube design with remote reservoir
  • One piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road
  • 7/8 Inch diameter induction hardened, chrome plated shock shaft
  • PTFE lined spherical bearings and application specific mounting hardware
  • 6061 aircraft grade aluminum CNC machined components
  • One-piece impact extruded aluminum cylinders offer excellent corrosion resistance and consistent finish
  • 100 Percent Rebuildable
  • 100 Percent Revalveable
  • All ICON 2.5 Series Piggyback and Remote Reservoir shocks can be upgraded to ICON's Compression Damping Control Valve (CDCV)

Electronic CDEV · 27821EP

ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks with CDEV 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.

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 Percent of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity.

Like all ICON'S Shock Absorbers, V.S. 2.5 Aluminum Series shocks with CDEV are 100 Percent rebuildable and 100 Percent revalveable.

Features and Benefits:

  • Compression Damping Electronic Valve (CDEV) is an electronically controlled valve that meters the flow of oil to regulate the amount of damping force that is created by the shock when compressed. This infinitely variable valve can react in less than 40ms and has the ability to make extremely precise adjustments for varying terrain. CDEV's hydraulic circuits are also custom tailored per application to create the highest resolution and dynamic range allowable for each specific vehicle. Powered by ICON Intelligent Control and proprietary ICON mobile app, the system uses information from the onboard G-force sensor and Gyroscope to perform calculations based on algorithms and user-defined settings to predict terrain and adjust shock settings via the CDEV accordingly.
  • ICON's CDE Valve technology allows for in vehicle adjustment of compression damping settings and active adjustment via the ICON Intelligent Control (IIC)
  • ICON's internal InchBump Zone Inch increases damping by 20 Percent to provide more control as the shock approaches full compression
  • One-piece, hard anodized, impact extruded aluminum cylinders offer excellent corrosion resistance and consistent finish
  • Remote reservoir design improves heat dissipation to reduce shock fade during prolonged use
  • Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range
  • Nitrogen charged monotube design with remote reservoir
  • One-piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road
  • 7/8 Inch diameter induction hardened, chrome plated shock shaft
  • PTFE lined spherical bearings and application specific mounting hardware
  • 6061 aircraft grade aluminum CNC machined components
