ICON K53402T 1.25-3" Lift Stage 2 Tubular UCA Suspension 2025-2026 4Runner 4WD

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 - achieves a level front-to-rear stance
• Tubular UCAs are included and required for this coilover length - Delta Joint Pro provides corrected front-end geometry, built-in additional caster, and improved suspension component clearance
• For on-vehicle caster and camber adjustability, upgrade to the Billet UCA version: ICON K53402
• Front differential drop kit (#55160) and polyurethane differential mounting bushings are included to maximize front suspension travel and prevent CV bind
• 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

• Stage 2 upgrade over Stage 1: adds ICON Tubular Delta Joint Pro UCAs providing corrected front-end geometry, built-in caster correction, and improved suspension component clearance at the taller lift heights
• ICON patented Delta Joint Pro (U.S. Pat. 10,731,700) - 90 degrees of total articulation, serviceable, rebuildable, greaseable, eliminates suspension bind through the full travel range
• Vehicle-specific 2.5 Series internal reservoir front coilovers deliver superior valving and increased piston area over stock, with 1.25-3" of height-adjustable front lift
• Included front differential drop kit and specifically designed coilover lengths work together to maximize available front suspension travel and prevent CV axle bind
• Included polyurethane differential mounting bushings replace soft OE units to limit differential movement under load
• Dual-rate rear coil springs - softer ride height rate for on-road comfort, firmer overload rate for bottoming resistance; 0.75" rear lift achieves level stance front to rear
• 2.0 Aluminum Series internal reservoir rear shocks with vehicle-specific valving balance front-to-rear suspension performance
• CAD-plated shock bodies with 7/8" front shafts and 5/8" rear shafts; FK rod end bearings for extended longevity and minimal deflection
• 100% bolt-on system - no drilling, cutting, or welding required

Specifications

• Front Lift Range: 1.25-3" - height-adjustable threaded coilover body, stock-equipped vehicle
• Rear Lift: 0.75" - dual-rate coil springs, stock-equipped vehicle

Product Description

The ICON K53402T is the Stage 2 Tubular UCA suspension system for the 2025-2026 Toyota 4Runner (4WD, non-AVS). Building directly on the Stage 1 K53401 foundation, Stage 2 adds ICON's Tubular Delta Joint Pro upper control arms - a critical upgrade that provides corrected front-end geometry, built-in additional caster for improved straight-line tracking and steering feel, and improved suspension component clearance at the taller lift heights. Each UCA features ICON's patented Delta Joint Pro (U.S. Pat. 10,731,700): a sealed, greaseable, and fully rebuildable joint with 90 degrees of total articulation that eliminates suspension bind through the full range of travel.

The 2.5 Series internal reservoir front coilovers, front differential drop kit, polyurethane differential bushings, dual-rate rear coil springs, and 2.0 Aluminum Series rear shocks are all carried over from Stage 1 - delivering the same baseline of 1.25-3" height-adjustable front lift, 0.75" of rear lift, and maximized front wheel travel with CV bind prevention. The Tubular version provides fixed built-in caster correction; for owners who want on-vehicle caster and camber adjustment, the Billet UCA version K53402 is available. Note: does not fit 4Runner models with AVS; ADAS recalibration required. All shocks are 100% rebuildable and re-tunable.
