ICON 59923P Omega 2.5 Series Rear Bypass Shocks with Remote Reservoir Pair for 2007-2021 Toyota Tundra

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. 2007-2021 TUNDRA RXT REAR 2.5 OMEGA BYPASS REMOTE RESERVOIR SHOCK PAIR

Upgrade the suspension performance of your 2007-2021 Toyota Tundra with the ICON Omega Series 2.5 rear bypass shock pair, part number 59923P. Designed specifically for the Tundra application, these shocks provide controlled, predictable damping during off-road driving while maintaining a smooth, comfortable ride on the street. Application-specific valving and a one-piece digressive piston help deliver consistent suspension performance across changing terrain and driving conditions.
The externally adjustable ICON Bypass Valve provides 28 detented compression and rebound settings in quarter-turn increments, allowing precise tuning without tools. An internal Bump Zone, formed by the 6061 billet aluminum manifold positioned below the shock top cap, adds damping force as the shock approaches full compression. This helps reduce harsh bottoming and improves control during high-velocity suspension movement. The remote reservoir design increases heat dissipation, helping minimize shock fade during extended off-road use.
Built for long-term serviceability, the ICON 59923P shocks feature one-piece impact-extruded aluminum cylinders, 6061 aircraft-grade aluminum components, premium 5WT shock oil, and a 7/8-inch induction-hardened chrome-plated shaft. PTFE-lined spherical bearings and application-specific mounting hardware support durable, precise operation. Replaceable bypass tubes help simplify service in the event of damage, while the fully rebuildable and revalveable design allows the shocks to be maintained and customized throughout their service life.
