ICON Vehicle Dynamics 2007-2021 Toyota Tundra 1-3" Lift Stage 1 Suspension System

The ICON Vehicle Dynamics Stage 1 Suspension System for 2007–2021 Toyota Tundra raises ride height 1–3" and replaces both front and rear damping with vehicle-specific tuned shocks, a 100% bolt-on upgrade that requires no drilling, cutting, or welding. The system ships as two assemblies: a 2.5 VS Internal Reservoir coilover kit for the front and a pair of 2.0 VS Internal Reservoir shocks for the rear.

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 for the Tundra

The front 2.5 VS coilovers carry an internal reservoir that keeps fluid temperatures lower under repeated compression cycles, preserving consistent damping when the terrain gets rough. Vehicle-specific valving means the shock tune was developed for the Tundra's weight and geometry rather than adapted from a universal calibration. The result is damping that works with the truck's factory behavior rather than against it.

The rear 2.0 VS Aluminum Series shocks use the same vehicle-specific valving approach to balance the truck's front-to-rear performance. A 5/8" polished chrome shaft and 6061 aircraft-grade aluminum CNC-machined components keep unsprung weight in check while resisting corrosion on the trail.

Adjustable Lift Without Sacrificing OEM Fitment

The coilover's threaded body allows lift height to be set anywhere in the 1–3" range, so the system can accommodate OEM wheels and tires at the lower end of the adjustment or larger aftermarket combinations at the upper end. ICON notes that OEM wheels and tires fit the system as configured. A CAD-plated coilover shock body and FK rod end bearings are included to extend service life and minimize deflection under load.

Features

• 2.5 VS Internal Reservoir Coilover (front): vehicle-specific tune, internal reservoir, CAD-plated body, 7/8" shaft, FK rod end bearings
• 2.0 VS Aluminum Series Shocks (rear, ×2): vehicle-specific valving, 5/8" polished chrome shaft, 6061 aluminum construction
• 1–3" adjustable lift: threaded coilover body, set to application without swapping components
• 100% bolt-on installation: no drilling, cutting, or welding required
• Fully serviceable shocks: both front and rear units can be rebuilt
• No change to towing capacity: increased wheel travel and ride quality over stock

Specifications

Who This Is For and Isn't

This system suits 2007–2021 Toyota Tundra owners who want 1–3" of lift with a measurable improvement in on- and off-road damping, and who prefer a bolt-on install that retains OEM towing capacity.

Above 2.5" of lift, factory upper control arms will not align properly; an aftermarket UCA is recommended for lifts in the 2.5–3" range. The recommended 35×12.50" tire size requires fender trimming. This system does not fit the Sequoia (the front coilover kit lists Sequoia compatibility for 2008–2022, but the complete Stage 1 system is validated for Tundra only).

Common Questions

Do I need new upper control arms with this system?

At lifts up to 2.5", the factory upper control arms on the 2007–2021 Toyota Tundra align correctly with this Stage 1 system. Beyond 2.5" of lift, the application notes for this system state that factory UCAs will not align properly and an aftermarket upper control arm is recommended.

Will my OEM wheels and tires still fit after installation?

Yes. ICON confirms OEM wheels and tires fit the 2007–2021 Tundra Stage 1 system. For larger aftermarket fitments, ICON recommends specific ICON Alloys wheel sizes; the recommended 35×12.50" tire size requires fender trimming.

What tools or modifications does installation require?

The Stage 1 system is a 100% bolt-on upgrade for the 2007–2021 Toyota Tundra. No drilling, cutting, or welding is required for the base install. Fender trimming is required if running the recommended 35×12.50" tire size.

What is included in the Stage 1 kit?

The kit includes one 2.5 VS Internal Reservoir front coilover assembly (part 58650, covering 2007–2021 Tundra) and two 2.0 VS Internal Reservoir rear shocks (part 56506). A spanner wrench for coilover preload adjustment is available separately.

Are the shocks rebuildable?

Yes. Both the front 2.5 VS coilovers and the rear 2.0 VS shocks in this Stage 1 system are fully serviceable, meaning they can be disassembled and rebuilt rather than replaced as a sealed unit.
