ICON Stage 9 2.5 CDXS Suspension System for 2022-2026 Toyota Tundra

The ICON Vehicle Dynamics Stage 9 2.5 Series CDXS Suspension System is a complete front-and-rear upgrade for the 2022–2026 Toyota Tundra, delivering 2–3.5" of front lift over stock (range varies by sub-model and engine; see application notes below) and up to 40% more front wheel travel than stock components. The system ships as four assemblies: 2.5 VS CDXS remote-reservoir front coilovers, tubular upper control arms with Delta Joint PRO, a sway bar drop kit, and 2.5 Aluminum Series CDXS remote-reservoir rear shocks.

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.

Dual-Speed Compression Damping Front and Rear

Every shock absorber in the Stage 9 system carries ICON's Compression Damping Dual Speed (CDXS) valving, which independently controls high-speed and low-speed compression force. Ten detented positions on each adjustment knob let a driver dial handling response and overall aggressiveness separately, tightening low-speed damping for cornering without sacrificing the high-speed compliance that absorbs sharp trail hits. Having matched CDXS tuning front and rear means a single adjustment session can balance the whole vehicle rather than chasing a compromise between mismatched components.

Remote Reservoirs and Increased Travel

The 2.5" front coilovers and rear shocks both use remote reservoirs to increase shock oil volume and heat-dissipation surface area. Under sustained hard use (repeated high-speed whoops or long rocky descents), this delays the onset of damper fade that results from overheating and cavitation. The larger 2.5" shock body and increased piston area over stock yield up to 40% more front wheel travel. The rear shocks add an internal Bump Zone that generates an additional 20% of damping force at the end of stroke to resist hard bottom-outs.

Corrected Geometry and Reduced Bind

The included tubular upper control arms are built with corrected front-end geometry and additional caster, and they replace the OE ball joint with ICON's rebuildable Delta Joint PRO (U.S. Pat. 10,731,700), which provides 90 degrees of total articulation and eliminates bind through full bump and droop travel. The sway bar drop brackets reposition the sway bar attachment point to reduce link bind across the suspension travel range, allowing the full wheel travel without overstressing OE sway bar components. All ICON shock absorbers in this system are fully rebuildable and re-tunable.

Features

• CDXS front coilovers (2.5 VS, remote reservoir): 10-position independent hi/low-speed compression adjustment, 2.5" shock body, vehicle-specific valving
• Tubular upper control arms with Delta Joint PRO: corrected geometry, added caster, 90° articulation, serviceable and rebuildable ball joint (U.S. Pat. 10,731,700)
• Sway bar drop kit: reduces OE sway bar link bind through full suspension travel
• 2.5 Aluminum Series CDXS rear shocks (remote reservoir): 10-position hi/low-speed adjustment, internal Bump Zone for 20% additional end-stroke damping
• Tire clearance: supports fitment of up to 35" tires (minor fender trimming and modifications may be required)
• Fully rebuildable: all shock absorbers are rebuildable and re-tunable

Who This Is For and Isn't

The Stage 9 system suits 2022–2026 Toyota Tundra owners who want a complete, tunable front-and-rear suspension upgrade with matched CDXS damping, corrected geometry, and clearance for up to 35" tires, whether the primary use is overlanding, high-speed desert running, or daily driving with occasional trail use. All lift figures are for a stock-equipped vehicle; added weight from accessories will alter the lift range.

This system is not compatible with Tundra models equipped with Load-Leveling Rear Height Control Air Suspension or Adaptive Variable Suspension (AVS). Vehicles equipped with a TRD aluminum skid plate also require ICON part #55164. 4WD models without the TRD Off-Road package require either the ICON Differential Drop (part #55156) or Toyota TRD axles to avoid potential front axle damage (not required for TRD Pro). Advanced Driver Assistance Systems (ADAS) require recalibration after installation.

Common Questions

What sub-models does this system fit, and does the lift range change by trim?

The Stage 9 system fits 2022–2026 Toyota Tundra models, but front lift range varies by sub-model and engine. Most i-Force gasoline sub-models achieve 2–3.5" of front lift over stock; most i-Force MAX hybrid sub-models achieve 2–3"; Tundra TRD Pro achieves 0–1.5"; and the SR5 with TRD Sport Suspension package achieves 3–4.5". All lift figures are for a stock-equipped vehicle, and added weight from accessories will alter the range.

Is this system compatible with factory air suspension or adaptive damping?

The ICON Stage 9 system for the 2022–2026 Toyota Tundra is not compatible with Load-Leveling Rear Height Control Air Suspension or with Adaptive Variable Suspension (AVS). Buyers should confirm which suspension package their specific vehicle carries before purchasing.

What additional parts or steps are required after installation?

Advanced Driver Assistance Systems (ADAS) require professional recalibration after the Stage 9 system is installed. Tundra 4WD models without the TRD Off-Road package need the ICON Differential Drop (part #55156) or Toyota TRD axles to prevent potential front axle damage. Vehicles with a TRD aluminum skid plate require ICON part #55164. A professional alignment is also required after any suspension lift installation.

What exactly is included in the Stage 9 system?

The Stage 9 system includes four assemblies: the 2.5 VS CDXS remote-reservoir front coilover kit (58770X), the tubular upper control arm kit with Delta Joint PRO (58461DJ), the sway bar drop kit (55154), and the 2.5 Aluminum Series CDXS remote-reservoir rear shock pair (57840XP). Wheels, tires, differential drop, skid plate spacers, and bump stop kits are sold separately.

Can the shocks be rebuilt or retuned after hard use?

All ICON shock absorbers in the Stage 9 system are fully rebuildable and re-tunable. The Delta Joint PRO ball joint in the upper control arms is also serviceable and rebuildable, which extends the service life of the control arm assembly rather than requiring full replacement.
