ICON Stage 4 2.5 Suspension System Tubular for 2023-2026 Toyota Sequoia TRD Pro

The ICON Vehicle Dynamics Stage 4 2.5 Suspension System (Tubular) 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 factory billet aluminum front upper control arms. The system pairs VS 2.5 Series remote reservoir front coilovers with dual-rate rear coil springs, tubular DOM rear lower links, and 2.5 Aluminum Series rear remote reservoir shocks for balanced, rebuildable performance on- and off-road.

TRD Pro UCAs Kept, Performance Raised

Most aftermarket suspension systems for the Sequoia require replacing the factory front upper control arms. This Stage 4 system uses a vehicle-specific coilover length and valving that works directly with the stock TRD Pro billet aluminum UCAs, preserving the OEM geometry investment while adding a larger 2.5" shock body and increased piston area. The result is maximum wheel travel without overstressing factory components, a meaningful difference for buyers who want improved capability without discarding parts that came on the truck.

Remote Reservoirs Front and Rear

Both the front coilovers and the rear 2.5 Aluminum Series shocks carry remote reservoirs. The added oil volume and heat-dissipation surface area resist the overheating and cavitation that cause damper fade under sustained hard use: washboard roads, repeated water crossings, or loaded highway miles in summer heat. The rear shocks also incorporate an internal Bump Zone that adds 20% of damping force at the end of travel to resist hard bottom-outs, a practical benefit when the Sequoia is loaded with passengers or gear.

Rear End Rebuilt for Level Stance and Articulation

The dual-rate rear coil springs use a softer primary rate for on-road comfort and a firmer overload rate for bottoming resistance, producing 2" of rear lift on a stock TRD Pro. That 2" of rear lift levels the stance front to rear when the front is set at its full 2.5" adjustment. The tubular rear lower links, made from 1-3/4" x .313-wall DOM steel tubing with a multi-stage black powder coat, add PTFE-lined FK rod ends for increased articulation and reduced deflection, plus multi-durometer bushings that require no periodic greasing.

Features

• Adjustable front lift: 1-2.5" of front ride height adjustability over stock
• TRD Pro UCA compatible: vehicle-specific coilover length designed for stock billet aluminum front upper control arms
• Remote reservoirs front and rear: increased oil volume and heat dissipation on all four corners
• Rear Bump Zone: internal feature on 2.5 Aluminum Series rear shocks adds 20% damping force at end of travel
• Tubular DOM rear lower links: 1-3/4" x .313-wall tubing, PTFE-lined FK rod ends, multi-durometer bushings, black powder coat
• Fully rebuildable: 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 1-2.5" of adjustable front lift and a level rear stance while keeping the factory billet aluminum front upper control arms. It is appropriate for buyers who use the Sequoia both on-road and off-road and want rebuildable, remote-reservoir damping on all four corners.

This system is designed exclusively for the Sequoia TRD Pro and is not compatible with non-TRD Pro Sequoia trims. Lift heights are based on a stock-equipped vehicle; adding accessories or cargo weight will alter the achieved lift range. Advanced Driver Assistance Systems (ADAS) require professional recalibration after installation. An ICON differential drop kit (part 55156) is recommended for TRD Pro fitment but is not included; if the diff drop is installed, the ICON skid plate spacer kit (part 55164) is also required and sold separately.

Common Questions

Will this system work with the factory front upper control arms on the Sequoia TRD Pro?

Yes. The ICON Stage 4 2.5 Suspension System (Tubular) for the 2023-2026 Toyota Sequoia TRD Pro uses a vehicle-specific coilover length engineered to retain and work with the stock billet aluminum front upper control arms. Replacing the factory UCAs is not required.

What lift heights does this system provide?

The Stage 4 2.5 system provides 1-2.5" of adjustable front lift and 2" of rear lift over stock on a stock-equipped Sequoia TRD Pro. Adding accessories or cargo weight to the vehicle will alter the achieved lift range.

Do the shocks need to be replaced if they wear out, or can they be serviced?

All ICON shock absorbers included in this Stage 4 system are fully rebuildable and re-tunable, so worn seals, fluid, or valving can be serviced rather than requiring full shock replacement.

Is a differential drop kit required for installation on the Sequoia TRD Pro?

An ICON differential drop kit (part 55156) is recommended for the Sequoia TRD Pro installation but is not required and is not included in this system. If the differential drop kit is installed, the ICON skid plate spacer kit (part 55164) is also required and must be purchased separately.

Does installation require any recalibration of vehicle safety systems?

Yes. Installing the ICON Stage 4 2.5 Suspension System on the 2023-2026 Toyota Sequoia TRD Pro requires professional recalibration of the vehicle's Advanced Driver Assistance Systems (ADAS) after installation is complete.
