ICON 2007-2022 Toyota Tundra 2.5 Series Shocks VS IR Coilover Kit | 58650

Product Description:
The ICON V.S. 2.5 Series Internal‑Reservoir Front Coilover Kit (SKU ICOK58650) is a vehicle‑specific upgrade engineered for front suspension applications on the 2007–2021 Toyota Tundra and 2008–2022 Toyota Sequoia.

Technical Features:

• Adjustable ride height providing approximately 1″ to 3″ of lift above stock when installed correctly on the specified vehicles. 

• Large 2.5″ diameter shock body with 7/8″ induction‑hardened chrome‑plated shaft and corrosion‑resistant CAD‑plated finish designed for durability and heat dissipation. 

• Internal nitrogen‑charged reservoir design (250 psi) to help maintain damping consistency and reduce cavitation during sustained or heavy duty use. 

• Vehicle‑specific tuning of lengths and valving for the Tundra/Sequoia platform to support larger wheel/tire combinations (e.g., up to 35″ recommended) while maintaining proper front geometry.

• Billet‑machined upper mount and PTFE‑lined spherical bearing help ensure smooth articulation and reduce unwanted compliance in the front end. 

Technical Considerations:
This kit is designed as a front‑end upgrade and does not include rear shocks, control arms or full suspension system components. The installer must assess compatibility with rear components, tires/wheels, and the overall vehicle build. The increased lift and altered front geometry may affect driveshaft angles, brake‑line clearance, steering geometry, and electronic system calibration. Proper installation includes full alignment (caster, camber, toe), attention to ride‑height matching, and verification of clearance under full suspension travel.

Expert FAQ:

1. What exactly is the lift range this kit supports?
   The kit supports approximately 1″ to 3″ of front lift over stock for the applicable 2007–21 Tundra and 2008–22 Sequoia models. 

2. What benefits does the internal reservoir shock provide versus a standard monotube?
   An internal reservoir increases oil and gas volume within the shock, improving heat capacity and reducing cavitation during heavy use, which results in more consistent damping performance and better control of the front end under load.

3. Does this kit include rear suspension components or rear shocks?
   No — this SKU is focused on the front coilover assembly only. Rear suspension upgrades (shocks/springs/control arms) must be addressed separately for balanced performance. 

4. Will larger tires or aftermarket wheels cause issues with this kit?
   Larger tires (such as 35″ diameter) are frequently supported when paired with this kit and proper clearance trimming. However, oversized wheels/tires, significant offsets, or other non‑stock components may require additional modifications for clearance and suspension geometry. 

5. What installation or maintenance steps should be taken after install?
   After installation, it’s critical to perform a full alignment, check all mounting hardware for correct torque, verify that shock body mounting clearance and travel are unobstructed, and inspect periodically for leaks, wear at bushings/spherical bearings, and full shock articulation under load.
