ICON Stage 1 Suspension System for 2000-2006 Toyota Tundra, 0-2.5" Lift

The ICON Stage 1 Suspension System for the 2000–2006 Toyota Tundra is a complete bolt-on front and rear upgrade that raises ride height 0–2.5 inches and increases wheel travel and damping ability over stock. The system ships as one 2.5 VS Internal Reservoir coilover kit for the front and two 2.0 VS NR monotube shocks for the rear, tuned together for balanced on-road and off-road performance.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Tuned Front-to-Rear Balance

The front 2.5 VS Internal Reservoir coilover uses vehicle-specific valving and an internal reservoir that dissipates heat during sustained off-road use, helping the shock maintain consistent damping when trail conditions demand repeated compression cycles. The rear 2.0 VS Aluminum Series monotube shocks carry the same vehicle-specific tuning philosophy, so the truck's front and rear damping characteristics work together rather than fighting each other over rough terrain.

Height-Adjustable Without Compromise

The coilover's threaded body allows ride height adjustment across the full 0–2.5 inch lift range without removing the shock from the vehicle. ICON notes that lift heights indicated are for a stock-equipped vehicle; a 700 lb/in Expedition coil is available separately for heavier-equipped builds. OEM wheels and tires fit within the lift range; ICON's own aftermarket wheel recommendations are 17×8.5 with 4.75" backspace, 18×9 with 5.00" backspace, or 20×9 with 5.00" backspace. The largest recommended tire without fender modification is 33×11.50".

Bolt-On Construction

Every component in the Stage 1 system installs without drilling, cutting, or welding. CNC-machined 6061 aircraft-grade aluminum components, a corrosion-resistant CAD-plated coilover body, 7/8" shaft FK rod end bearings, and 5/8" polished chrome rear shafts are the same hardware ICON uses across its performance lineup. ICON states the shocks are fully serviceable, and a bump stop spacer kit is available separately to increase threads showing beyond the maximum recommendation.

Specifications

Who This Is For and Isn't

This system suits 2000–2006 Toyota Tundra owners who want a bolt-on lift of up to 2.5 inches with improved damping for mixed on-road and off-road driving, and who want to run aftermarket wheels up to 20 inches or tires up to 33×11.50" without fender modification.

This system fits only the 2000–2006 Toyota Tundra and does not fit any other model year. It does not include a spanner wrench, bump stop spacer kit, or Expedition-rate coil spring, each of which is sold separately. Tires larger than 33×11.50" will require fender trimming or other modifications.

Common Questions

What vehicles does this suspension system fit?

The ICON Stage 1 Suspension System is designed specifically for the 2000–2006 Toyota Tundra. It does not fit earlier or later Tundra generations, and ICON does not list any other make or model as compatible with this kit.

Does installation require cutting, drilling, or welding?

No. The ICON Stage 1 system for the 2000–2006 Tundra is a 100% bolt-on kit. ICON states that no drilling, cutting, or welding is necessary for installation.

Will OEM wheels and tires still fit after installing this system?

Yes. ICON confirms OEM wheels and tires are compatible with this Stage 1 system. The largest recommended aftermarket tire without fender modification is 33×11.50"; larger tires may fit but will require fender trimming or other modifications per ICON's application notes.

What is included in the Stage 1 kit?

The Stage 1 kit includes one 2.5 VS Internal Reservoir front coilover kit (part 58620) and two 2.0 VS NR rear monotube shocks (part 56504). A spanner wrench, bump stop spacer kit, and Expedition-rate coil spring are not included. Each is sold separately.

Can the lift height be adjusted after installation?

Yes. The front coilover's threaded body allows ride height adjustment across the full 0–2.5 inch range. ICON notes that stated lift heights are based on a stock-equipped vehicle; a heavier build may require the optional 700 lb/in Expedition coil, sold separately.
