ICON V.S. 2.5 Series Extended Travel Front Coilover Kit for 2000-2006 Toyota Tundra and 2001-2007 Toyota Sequoia

The ICON V.S. 2.5 Series Extended Travel Front Coilover Kit with Internal Reservoir is a vehicle-specific front suspension upgrade for the 2000–2006 Toyota Tundra and 2001–2007 Toyota Sequoia, delivering 0–2.5 inches of lift height adjustability through a 2.5-inch diameter shock body with an internal reservoir. This kit fits both the Tundra (2000–2006) and Sequoia (2001–2007) and is sold as a front coilover set; rear shocks are sold separately.

Vehicle-Specific Valving for Real-World Performance

ICON tunes shock length and damping valving specifically for the Tundra and Sequoia platform rather than adapting a universal shock to fit. That vehicle-specific calibration means the damping curve matches the actual sprung weight, geometry, and use patterns of these trucks, translating to predictable handling on pavement and composed, controlled suspension movement on dirt and trail. The 2.5-inch shock body provides increased piston surface area over the stock unit, which gives the shock more fluid volume to work with and more consistent damping force across a wider range of inputs.

Internal Reservoir for Consistent Damping

The internal reservoir separates the shock's oil and nitrogen charge, reducing heat-induced fade during sustained off-road use. Where a standard monotube or twin-tube shock can cavitate or lose damping consistency on repeated hard compressions, the reservoir design maintains fluid separation and keeps damping response stable. The shock body is CAD-plated for corrosion resistance, the shaft measures 7/8-inch diameter, and CNC-machined 6061 aircraft-grade aluminum components are used throughout. FK rod end bearings replace rubber bushings at the mounting points, reducing deflection and extending service life. The shocks are fully rebuildable and re-tunable.

Adjustable Lift and Larger Tire Clearance

The threaded collar design allows lift height to be set anywhere from 0 to 2.5 inches above stock, so the final ride height can be dialed in after installation rather than fixed at purchase. ICON's own technical notes confirm OEM wheels and tires fit at the supported lift range. For aftermarket fitments, ICON identifies 17x8.5-inch wheels with 4.75-inch backspace, 18x9-inch wheels with 5.00-inch backspace, and 20x9-inch wheels with 5.00-inch backspace as compatible. Recommended aftermarket tire size is 33x11.50 inches; larger tires may fit but fender trimming or other modifications will be required.

Features

• 0–2.5-inch lift adjustability: threaded collar allows on-vehicle height tuning after installation
• 2.5-inch shock body with internal reservoir: increased piston area and fluid separation for consistent damping
• Vehicle-specific length and valving: tuned for the Tundra/Sequoia platform, not a universal application
• 6061 aircraft-grade aluminum CNC components: CAD-plated shock bodies with 7/8-inch diameter shafts
• FK rod end bearings: reduced deflection and longer service life versus rubber bushings
• Fully rebuildable and re-tunable: serviceable in the field or at a shop without replacing the entire unit

Specifications

Who This Is For and Isn't

This kit suits 2000–2006 Toyota Tundra and 2001–2007 Toyota Sequoia owners who want adjustable front lift between 0 and 2.5 inches, improved off-road wheel travel, and a rebuildable shock they can retune as their build evolves. It is appropriate for overlanding, trail driving, and daily use where a more capable front suspension is the goal.

These extended-travel coilovers require aftermarket front upper control arms and are not compatible with stock front upper control arms. Owners who want to retain OEM upper control arms should consider the standard-travel version, ICON part number 58620. Rear shocks, a spanner wrench, bump stop spacer kit, and the optional 700 lb/in expedition coil spring are not included and are sold separately. This kit covers the front suspension only.

Common Questions

Do these coilovers work with stock front upper control arms?

No. The ICON V.S. 2.5 Series Extended Travel coilovers require aftermarket front upper control arms. The extended shock travel exceeds the range of the OEM upper control arm. Owners who want to keep stock upper control arms should use the standard-travel version, ICON part number 58620, instead.

What lift height can I set with this kit?

The ICON V.S. 2.5 Series Extended Travel coilovers are adjustable from 0 to 2.5 inches of lift over stock. Lift height is set via the threaded collar and can be adjusted after installation. ICON notes that indicated heights are based on a stock-equipped vehicle.

Will my OEM wheels and tires still fit after installation?

Yes. ICON confirms OEM wheels and tires fit within the supported lift range of this coilover kit. For aftermarket fitments, ICON recommends 17x8.5-inch, 18x9-inch, or 20x9-inch wheels with specific backspacing, and a maximum tire size of 33x11.50 inches without fender modification.

Are rear shocks included in this kit?

No. This kit covers the front suspension only. ICON recommends pairing these coilovers with ICON 2.0 or 2.5 Aluminum Series rear shock absorbers to balance vehicle control front to rear, but those rear shocks are sold separately.

Can these shocks be rebuilt or retuned later?

Yes. The ICON V.S. 2.5 Series coilovers are fully rebuildable and re-tunable, meaning the valving and internals can be serviced or adjusted without replacing the entire shock. This makes them a long-term investment for builds that evolve over time.

Is a heavier-duty spring available for a more heavily equipped vehicle?

Yes. ICON offers a 700 lb/in expedition coil spring as an optional upgrade for more heavily equipped Tundra and Sequoia builds. This spring is sold separately and is not included with the coilover kit.

Does this product carry a California Proposition 65 warning?

Yes. This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm. This warning applies to California residents.
