ICON Vehicle Dynamics Stage 9 2.5 Suspension System for 2023-2026 Toyota Sequoia TRD Pro

The ICON Vehicle Dynamics Stage 9 2.5 Suspension System is a complete front-and-rear suspension upgrade for the 2023-2026 Toyota Sequoia TRD Pro, delivering 1-2.5" of adjustable front lift and 2" of rear lift while retaining the truck's stock billet aluminum front upper control arms. The system pairs 2.5 Series CDEV remote reservoir front coilovers with dual-rate rear coil springs, billet aluminum rear lower links, and 2.5 Aluminum Series CDEV remote reservoir rear shocks for balanced, electronically managed damping at all four corners.

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.

Active Damping That Reads the Road

Each shock in the Stage 9 system carries ICON's Compression Damping Electronic Valve (CDEV), an electronically controlled valve that meters oil flow to regulate damping force during compression. The valve reacts in less than 40ms and adjusts continuously across its full range, so the Sequoia's suspension responds to changing terrain without driver input. ICON Intelligent Control (IIC) drives those adjustments using onboard G-force sensors and a gyroscope, processing vehicle movement data against user-defined settings through the ICON mobile app. Note: an iOS device is required to run the IIC app.

TRD Pro Compatibility Without Sacrificing Travel

The front coilovers use a vehicle-specific shock length engineered to work with the Sequoia TRD Pro's stock billet aluminum upper control arms, so there is no need to replace or modify OEM components to gain lift. The larger 2.5" shock body and increased piston area over stock components maximize wheel travel within the constraints of the OE upper control arms. Adjustable collars allow front ride height to be set anywhere in the 1-2.5" lift range over stock, giving owners flexibility to dial in stance and clear tires up to 35" (minor fender trimming and modifications may be required).

Rear Components Built for Level Stance and Hard Use

Dual-rate rear coil springs use a softer rate at ride height and a firmer overload rate as the suspension compresses, providing on-road comfort alongside resistance to bottoming out. These springs are designed to deliver 2" of rear lift on a stock Sequoia TRD Pro, leveling the stance front to rear. The billet rear lower links are CNC machined from 6061 aluminum, anodized for corrosion resistance, and fitted with PTFE-lined FK rod ends for increased articulation and reduced deflection; on-vehicle length adjustment is available through ICON's double adjuster system. The 2.5 Aluminum Series rear shocks add an internal Bump Zone that generates an additional 20% of damping force at the end of travel to control hard bottom-outs, and remote reservoirs keep operating temperatures lower during sustained hard use.

Features

• CDEV at every corner: electronically controlled compression damping valve reacts in under 40ms for continuous terrain-responsive adjustment
• IIC app control: ICON Intelligent Control uses onboard G-force sensor and gyroscope data to make near-instant damping changes; iOS device required
• TRD Pro UCA compatibility: vehicle-specific front coilover length designed for use with stock Sequoia TRD Pro billet upper control arms
• 1-2.5" adjustable front lift / 2" rear lift: lift heights based on a stock-equipped vehicle; added accessories will alter the lift range
• Billet 6061 aluminum rear lower links: CNC machined, anodized, with PTFE-lined FK rod ends and ICON double adjuster for on-vehicle pinion angle adjustment
• Fully rebuildable shocks: all ICON shock absorbers in this system are rebuildable and re-tunable

Specifications

Who This Is For and Isn't

This system suits 2023-2026 Toyota Sequoia TRD Pro owners who want electronically managed lift and leveling while keeping the truck's stock billet upper control arms, and who want the ability to run tires up to 35" with a level front-to-rear stance for mixed on- and off-road use.

This system is designed for the Sequoia TRD Pro specifically and is not compatible with non-TRD Pro Sequoia trims. It does not include a differential drop kit (ICON part 55156, recommended for TRD Pro installations) or a skid plate spacer kit (required if the diff drop is installed); those are sold separately. An iOS device is required to use the IIC app; Android is not supported. ADAS recalibration is required after installation. Lift heights are for a stock-equipped vehicle and will vary with added accessories or cargo weight.

Common Questions

Does this system work with the Sequoia TRD Pro's stock front upper control arms?

Yes. The Stage 9 system's front coilovers use a vehicle-specific shock length engineered for compatibility with the stock billet aluminum upper control arms on the 2023-2026 Toyota Sequoia TRD Pro, so the OEM front UCAs do not need to be replaced to install this system.

What lift height does this system provide?

The Stage 9 system provides 1-2.5" of adjustable front lift and 2" of rear lift over stock on a stock-equipped 2023-2026 Toyota Sequoia TRD Pro. Adding accessories or cargo weight will alter the actual lift achieved.

Is the differential drop kit included?

No. For Sequoia TRD Pro installations, ICON recommends the ICON differential drop kit (part 55156), which is sold separately. If the differential drop kit is installed, the ICON skid plate spacer kit (part 55164) is also required and sold separately.

What app or device is needed to control the CDEV system?

The ICON Intelligent Control (IIC) system is managed through the ICON mobile app, which requires an iOS-operated device. Once the system is configured, it operates automatically without driver input using onboard G-force and gyroscope data.

Does installation require any recalibration of vehicle safety systems?

Yes. Installing the Stage 9 suspension system on the 2023-2026 Toyota Sequoia TRD Pro requires recalibration of the vehicle's Advanced Driver Assistance Systems (ADAS) after installation is complete.
