The ICON Vehicle Dynamics Stage 4 3.0 Suspension System (K53254) represents the pinnacle of suspension engineering for the 2023-2024 Toyota Sequoia. This comprehensive kit combines active electronic damping technology with premium billet aluminum components to deliver exceptional on-road comfort and extreme off-road capability with 3-4.25 inches of adjustable lift height.

3.0 Series CDEV Front Coilovers with ICON Intelligent Control:

• Vehicle-specific 3.0 Series remote reservoir coilovers with Compression Damping Electronic Valves (CDEV)
• 50% more piston surface area than 2.5 Series shocks in the ride zone, 100% more in the Bump Zone
• Multi-stage hydraulic Bump Zone increases bottom-out resistance through the last 40% of travel
• ICON Intelligent Control (IIC) system monitors G-forces and terrain up to 1,000 times per second
• Near-instantaneous compression damping adjustments delivered in under 40 milliseconds
• Wireless control via smartphone app with user-defined settings
• Up to 40% increase in wheel travel over stock for superior off-road capability

Billet Aluminum Front Upper Control Arms:

• CNC machined 6061 aluminum construction with anodized finish
• Corrected front-end geometry for improved handling and tire wear
• On-vehicle caster and camber adjustment for precise alignment
• Serviceable and rebuildable ICON Delta Joint PRO with 90 degrees of articulation
• Eliminates ball joint bind through full suspension travel

Rear Suspension Components:

• 3.0 Series remote reservoir rear shocks with CDEV technology
• Active compression damping adjustment synchronized with front coilovers
• Increased internal oil volume and external surface area for superior heat dissipation
• Dual-rate rear coil springs with softer ride height rate and firmer overload rate
• 2 inches of rear lift for level stance with front lift height
• Billet 6061 aluminum adjustable rear upper and lower links with PTFE-lined FK rod ends
• Billet aluminum adjustable rear track bar with double adjuster design for easy on-vehicle adjustment
• CNC machined from solid 6061 aluminum bar with anodized finish

Additional Components:

• Front sway bar drop brackets minimize link bind through suspension travel
• Allows full range of wheel travel without overstressing OE components
• Complete hardware and installation brackets included

Performance Specifications:

• Adjustable front lift: 3-4.25 inches over stock height
• Rear lift: 2 inches over stock (non-TRD models)
• Accommodates up to 35-inch tires with proper setup
• All shock absorbers are fully rebuildable and re-tunable

Important Installation Notes:

• 4WD models without TRD Off-Road Package require ICON Diff Drop (Part #55156) or Toyota TRD axles to prevent front axle damage
• Not compatible with Adaptive Variable Suspension (AVS) equipped vehicles
• Requires recalibration of Advanced Driver Assistance Systems (ADAS) after installation
• TRD Off-Road Package and TRD Pro models will experience reduced lift heights (1-2.5" front, 0" rear)
• Vehicles with automatic leveling headlights require additional part #55153

This Stage 4 3.0 system delivers balanced vehicle control from front to rear with electronically controlled damping at all four corners. The combination of larger 3.0 Series shocks, intelligent active damping, and precision billet aluminum components creates an unmatched driving experience whether conquering technical terrain or cruising the highway. The system maintains excellent on-road manners while providing the capability to handle the most demanding off-road conditions with confidence.
