ICON K53401 1.25-3" Lift Stage 1 Suspension System for 2025-2026 Toyota 4Runner

Vehicle Fitment

• 2025-2026 Toyota 4Runner (4WD, All Non-AVS Trims, All Engines) - 1.25-3" front lift, 0.75" rear lift

Fitment Notes

• 4WD models ONLY - does not fit 2WD 4Runner
• Does NOT fit models equipped with Adaptive Variable Suspension (AVS)
• Front lift range of 1.25-3" is height-adjustable via the threaded coilover body - lift heights based on a stock-equipped vehicle
• Rear lift of 0.75" provided by included dual-rate rear coil springs - designed to achieve a level front-to-rear stance at the mid-range front lift heights
• ICON Delta Joint Pro front upper control arms are recommended to maintain proper wheel alignment above 2" of front lift - sold separately (#58692 front UCA kit)
• Front differential drop kit (#55160) is included and required to maximize available front suspension travel and prevent CV bind
• Polyurethane differential mounting bushings are included and replace the soft OE bushings to limit differential movement under load
• Recommended aftermarket tires: 33" x 11.50" - larger tires may fit with fender trimming
• Requires recalibration of Advanced Driver Assistance Systems (ADAS) after installation
• Shocks are fully serviceable and rebuildable

Features

• Vehicle-specific 2.5 Series internal reservoir front coilovers deliver ICON-engineered valving, increased piston area over stock, and 1.25-3" of height-adjustable front lift for superior on- and off-road performance
• Included front differential drop kit and specifically designed coilover lengths work together to maximize available front suspension travel and prevent CV axle bind at the taller lift heights
• Included polyurethane differential mounting bushings replace the soft OE units to limit differential movement under load - improving front-end consistency and control
• Dual-rate rear coil springs provide a softer ride height rate for on-road comfort with a firmer overload rate for bottoming resistance - 0.75" of rear lift achieves a level stance front to rear
• 2.0 Aluminum Series internal reservoir rear shocks provide vehicle-specific valving to balance front-to-rear suspension performance
• Height-adjustable threaded coilover body - 1.25-3" of front lift without disassembly
• 100% bolt-on system - no drilling, cutting, or welding required

Specifications

• Front Lift Range: 1.25-3" - height-adjustable, stock-equipped vehicle

Product Description

The ICON K53401 is a complete Stage 1 suspension system for the 2025-2026 Toyota 4Runner (4WD, non-AVS). As ICON's entry-level system for the 5th Gen 4Runner platform, it delivers a meaningful performance and lift upgrade over stock with 1.25-3" of height-adjustable front lift via 2.5 Series internal reservoir coilovers, paired with 0.75" dual-rate rear coil springs designed to achieve a level stance front to rear. A critical inclusion in this kit is the front differential drop kit (#55160) and polyurethane differential mounting bushings - these work together with ICON's specifically designed coilover lengths to maximize available front wheel travel and prevent CV axle bind at the taller lift heights of this platform.

At the rear, 2.0 Aluminum Series internal reservoir shocks with vehicle-specific valving complete the system with balanced front-to-rear damping performance. ICON strongly recommends adding Delta Joint Pro front upper control arms (sold separately) for builds exceeding 2" of front lift to maintain proper wheel alignment. Note: this system does not fit 4Runner models equipped with Adaptive Variable Suspension (AVS). ADAS recalibration is required after installation. All shocks are 100% rebuildable and re-tunable for long-term serviceability.
