ICON 59910P Omega Series 2.5 VS Remote Reservoir Rear Shocks for Toyota FJ Cruiser, 4Runner and Lexus GX

ICON Omega Series Bypass 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 length but allow the user to customize the ride characteristics to their liking through adjustment of the bypass valves. Like all ICON shock absorbers, Omega Series shocks are 100% rebuildable and 100% revalveable. ICON’s 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 a significant increase in damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. The ICON Bypass Valve is an externally adjustable valve that restricts oil flow through the bypass tube and provides 28 settings of compression and rebound adjustment with no tools required. 2007-2014 FJ CRUISER/2003-UP 4RUNNER/2003-UP GX470/460 1-3" LIFT REAR OMEGA 2.5 VS REMOTE RESERVOIR SHOCK PAIR TECH NOTE: Will not fit models with factory rear air suspension. Vehicles equipped with rear air suspension require rear coil conversion, ICON part number 56110, and rear coil springs, ICON part number 52700 or 52800.

• One piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road
• Internal “Bump Zone” increases damping force to provide more control as the shock approaches full compression
• Hand adjustable bypass valves with 28 detented settings at quarter turn increments for precise suspension tuning
• 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
• 6061 aircraft grade aluminum CNC machined components
• Bypass tubes are replaceable in the event of damage
• 100% Revalveable
• 100% Rebuildable

Upgrade rear suspension control with the ICON Omega Series 2.5 VS remote reservoir shock pair, part number 59910P. Designed for 2007–2014 Toyota FJ Cruiser, 2003 and newer Toyota 4Runner, and 2003 and newer Lexus GX 470/GX 460 models with 1–3 inches of lift, these shocks provide enhanced off-road performance while maintaining a controlled, comfortable ride on the street. Application-specific length and valving deliver dependable suspension behavior across varied terrain, while externally adjustable bypass valves let you fine-tune compression and rebound without tools.
The ICON Bypass Valve provides 28 detented adjustment settings for precise tuning across the full adjustment range. A 6061 billet aluminum manifold creates an internal Bump Zone that increases damping force as the shock approaches full compression, helping control high-velocity suspension movement and reduce harsh bottom-out events. Remote reservoirs improve heat dissipation during prolonged or demanding use, helping minimize shock fade and maintain consistent performance. Premium-grade 5WT shock oil supports reliable damping across a broad temperature range.
The Omega Series features a one-piece digressive piston with vehicle-specific valving, one-piece impact-extruded aluminum cylinders, CNC-machined 6061 aircraft-grade aluminum components, and a 7/8-inch induction-hardened chrome-plated shock shaft. PTFE-lined spherical bearings and application-specific mounting hardware support accurate fitment and long-term durability. Replaceable bypass tubes provide serviceability in the event of damage, and the shocks are fully rebuildable and revalveable for continued customization and maintenance.
This ICON 59910P shock pair does not fit vehicles equipped with factory rear air suspension. Those applications require a rear coil conversion using ICON part number 56110 along with ICON rear coil springs, part number 52700 or 52800. Verify vehicle year, model, suspension configuration, and lift height before installation.
