ICON Stage 9 Suspension System 2023-2026 Toyota Sequoia 3-4.5" Lift Tubular CDCV TRD

The ICON Vehicle Dynamics Stage 9 is a complete suspension system for the 2023–2026 Toyota Sequoia, delivering 3–4.5" of front lift and 4" of rear lift on non-TRD models (1–2.5" front and 2" rear on TRD Off-Road and TRD Pro trims) through five matched component kits: VS 2.5 Series CDCV remote reservoir front coilovers, a tubular upper control arm kit with Delta Joint PRO, a sway bar drop kit, 2.5 Aluminum Series CDCV rear remote reservoir shocks, and TRD dual-rate rear coil springs.

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.

Ten-Setting Compression Damping on Every Shock

Every shock absorber in the Stage 9 system (front coilovers and rear shocks alike) carries an externally adjustable Compression Damping Control Valve (CDCV). The CDCV restricts oil flow into the remote reservoir across 10 discrete settings, letting the driver dial from a soft street tune to a firm off-road setting without removing a wheel. That range matters on a vehicle as capable as the Sequoia: the same system that absorbs freeway expansion joints comfortably can be stiffened for high-speed desert running or rock crawling without swapping components.

Geometry Correction Built Into the Control Arms

The included tubular steel upper control arm kit corrects front-end geometry, adds caster, and improves suspension component clearance for the 2023–2026 Sequoia platform. The OE ball joint is replaced by the ICON Delta Joint PRO, a serviceable, rebuildable joint with 90 degrees of total articulation (U.S. Pat. 10,731,700), which allows full bump and droop travel without bind. The included sway bar drop brackets reduce bind in the OE sway bar links through the full travel range, so no stock component is overstressed at the new ride height.

Remote Reservoirs and Increased Travel Front and Rear

The VS 2.5 Series front coilovers use a 2.5" shock body and increased piston area to deliver up to 40% more wheel travel than stock. Remote reservoirs on both the front coilovers and rear shocks increase oil volume and heat-dissipation surface area, resisting cavitation and damper fade under sustained hard use. 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. The dual-rate rear coil springs pair a softer ride-height rate with a firmer overload rate for on-road comfort and off-road bottoming resistance.

Features

• CDCV on all shocks: 10 externally adjustable compression damping settings, front and rear
• VS 2.5 Series front coilovers: 2.5" body, remote reservoir, up to 40% more travel than stock
• Tubular UCAs with Delta Joint PRO: corrected geometry, added caster, 90° articulation, rebuildable (U.S. Pat. 10,731,700)
• 2.5 Aluminum Series rear shocks: remote reservoir, internal Bump Zone for 20% additional end-travel damping
• Dual-rate rear coil springs: 4" rear lift (non-TRD) or 2" rear lift (TRD Off-Road / TRD Pro)
• Fully rebuildable and re-tunable: all ICON shock absorbers are serviceable

Specifications

Who This Is For and Isn't

The Stage 9 system suits 2023–2026 Toyota Sequoia owners on 4WD models who want adjustable lift, significantly increased wheel travel, and tunable compression damping for mixed street and off-road use, including fitment of up to 35" tires. TRD Off-Road and TRD Pro owners should note the lower lift range (1–2.5" front, 2" rear) this system produces on their trims; buyers wanting shorter rear ride heights on non-TRD models should consider kit K53239T instead.

This system is not compatible with Sequoia models equipped with Load-Leveling Rear Height Control Air Suspension or Adaptive Variable Suspension (AVS). Installation on 4WD models without the TRD Pro package requires either the ICON Differential Drop Kit (Part 55156) or Toyota TRD axles to avoid front axle damage. Sequoias equipped with the TRD aluminum skid plate also require Part 55164. Advanced Driver Assistance Systems (ADAS) must be professionally recalibrated after installation.

Common Questions

What lift height does this system produce on a TRD Off-Road or TRD Pro Sequoia?

On a 2023–2026 Toyota Sequoia equipped with the TRD Off-Road package or TRD Pro, the Stage 9 system produces 1–2.5" of front lift and 2" of rear lift over stock. Non-TRD trims achieve 3–4.5" of front lift and 4" of rear lift over stock, because the TRD suspension package starts from a higher baseline ride height.

Is this system compatible with Sequoias that have air suspension or Adaptive Variable Suspension?

No. The ICON Stage 9 system for the 2023–2026 Toyota Sequoia is not compatible with vehicles equipped with Load-Leveling Rear Height Control Air Suspension or Adaptive Variable Suspension (AVS). Buyers with either of those factory systems should not order this kit.

Does a 4WD Sequoia need any additional parts beyond what is included in the kit?

On 4WD Sequoia models without the TRD Pro package, ICON recommends adding the ICON Differential Drop Kit (Part 55156) or Toyota TRD axles to prevent front axle damage. TRD Pro models do not require this additional step. Sequoias with a factory TRD aluminum skid plate also require Part 55164 as a separate purchase.

What compression damping adjustment does the Stage 9 system offer?

The ICON Stage 9 system equips every shock absorber, both the VS 2.5 Series front coilovers and the 2.5 Aluminum Series rear shocks, with an externally adjustable CDCV that provides 10 settings of compression damping force ranging from soft to hard, without requiring shock removal.

Does installation require recalibration of driver assistance systems?

Yes. Installing the ICON Stage 9 suspension system on a 2023–2026 Toyota Sequoia requires professional recalibration of Advanced Driver Assistance Systems (ADAS) after the install is complete. This applies regardless of trim level.
