ICON 2023-2025 Toyota Sequoia, 3-4.5" Lift, Stage 4 Suspension System, Tubular (K53234T)

ICON 2023-2025 Toyota Sequoia 3-4.5" Lift Stage 4 Suspension System (Tubular)

The ICON Vehicle Dynamics Stage 4 Suspension System (K53234T) is a high-performance, fully engineered suspension upgrade designed for the 2023–2025 Toyota Sequoia. Built for maximum off-road capability and refined on-road comfort, this system delivers increased wheel travel, superior damping control, and aggressive stance capability for up to 35” tires. Featuring ICON 2.5 Series threaded-body coilovers, tubular upper control arms, sway bar drop kit, and dual-rate rear coil springs, this system is designed for enthusiasts who demand top-tier articulation, strength, and overland-ready durability. 

3”–4.5” Adjustable Front Lift for Maximum Stance and Clearance

The ICON 2.5 Series front coilovers provide adjustable lift from 3” to 4.5” over stock, allowing precise tuning for ride height, tire fitment, and suspension geometry. This adjustability supports larger wheel and tire combinations while maintaining proper alignment and improved off-road articulation.

2.5 Series Internal Reservoir Coilovers for High-Performance Damping

The front suspension utilizes ICON’s 2.5 Series internal reservoir coilovers, engineered to dissipate heat more effectively and maintain consistent damping under heavy loads and extreme terrain. This design significantly increases wheel travel while delivering a controlled, predictable ride in all conditions.

Tubular Upper Control Arms with Delta Joint PRO

This system includes heavy-duty tubular upper control arms designed to correct suspension geometry after lifting and improve overall front-end strength. Equipped with ICON’s Delta Joint PRO, they provide high articulation, reduced bind, and improved alignment range for enhanced durability and performance. 

Sway Bar Drop Kit for Improved Suspension Travel

The included sway bar drop brackets reduce preload and binding in the factory sway bar links, allowing the suspension to cycle more freely. This results in smoother articulation and improved off-road performance without overstressing OEM components. 

Dual-Rate Rear Coil Springs for Load Handling and Comfort

The rear suspension features dual-rate coil springs engineered for a balance of comfort and load-carrying capability. A softer initial rate improves ride quality during daily driving, while a firmer secondary rate provides stability under load and improved bottom-out resistance for overland applications.

ICON 2.0 Aluminum Series Rear Shocks

Rear damping is handled by ICON 2.0 Aluminum Series nitrogen-charged monotube shocks with internal reservoirs, specifically tuned for the Sequoia platform. These shocks provide balanced front-to-rear performance, improved stability, and consistent damping across varying terrain conditions.

Maximum Wheel Travel and Reinforced Suspension Geometry

This Stage 4 system is engineered to significantly increase wheel travel while maintaining drivetrain reliability and corrected suspension geometry. The combination of long-travel coilovers and upgraded control arms allows for up to 40% increased front travel compared to stock.
