The ICON Vehicle Dynamics Stage 4 complete suspension system for the 2023-2025 Toyota Sequoia builds upon the ICON threaded-body V.S. 2.5 Series Coilovers with the addition of adjustable billet aluminum front upper control arms. This system offers improved on- and off-road performance as well as improved alignment specs with front-end lift and leveling for a proper stance and fitment of up to 35" tires. To compliment the internal reservoir coilover shock and billet control arm combo, a sway bar drop kit for the front of the truck is included along with dual rate coil springs and our proven 2.0 nitrogen charged monotube shocks with internal reservoirs for the rear. This Stage 4 system features the 2023-2025 Toyota Sequoia VS 2.5 Series internal reservoir front coilovers. These adjustable coilovers allow up to 3-4.5” of lift height adjustability over stock when using the ICON billet aluminum front upper control arms, allowing the use of larger, more aggressive wheel and tire combinations. ICON’s Vehicle-specific shock length and valving along with the larger 2.5” shock body and increased piston area over stock components yield the maximum travel possible (up to 40% increase over stock) along with superior ride quality and suspension performance both on- and off-road. The included ICON billet aluminum upper control arm kit is designed to improve the overall performance of the 2023-2025 Toyota Sequoia with corrected front-end geometry, increased on-vehicle camber and caster adjustment, and improved suspension component clearance. Additionally, replacing the OE ball joint with the all-new, serviceable, and rebuildable ICON Delta Joint PRO allows for full bump and droop travel of the front suspension while eliminating bind. The included sway bar drop brackets help minimize sway bar link bind through the suspension travel range. This helps the suspension move more freely and allows for the full range of wheel travel without overstressing any OE components. The dual-rate rear coil design provides a softer ride height spring rate with a firmer overload rate that combine to deliver on-road comfort with excellent bottoming resistance and superior off-road performance. Designed for shorter rear ride heights, these coil springs yield 2" of rear lift over stock on a non-TRD Sequoia or 0” of rear lift height on a Sequoia equipped with the TRD Off-Road package, allowing for level a stance front to rear. Rounding out the Stage 4 suspension system are V.S. 2.0 Aluminum Series rear shocks specially tailored for the 2023-2025 Sequoia. The 2.0 Aluminum Series shocks are a high-quality upgrade for the everyday street driver and weekend warrior looking for improved on and off-road performance. Their pairing with the ICON 2.5 Series front coilovers results in balanced vehicle control from front to rear and an excellent overall driving experience for your Sequoia.
