ICON K53064T Stage 4 Tubular UCA System 0-3.5" for 2010-2024 4Runner/FJ Cruiser

Vehicle Fitment

• 2010-2024 Toyota 4Runner (All Trims | 4.0L V6 | 4WD)
• 2010-2014 Toyota FJ Cruiser (All Trims | 4.0L V6 | 4WD)

Fitment Notes

• Compatible with KDSS (Kinetic Dynamic Suspension System) equipped vehicles. Vehicles with KDSS do not use the front sway bar relocation brackets included in the kit. KDSS-equipped vehicles additionally require ICON Rear Adjustable Track Bar Part #54200, sold separately.
• Certain model years require trimming for proper front remote reservoir bracket fitment.
• Front coilovers are height adjustable from 0-3.5" over stock. Coilover heights are indicated for a stock-equipped vehicle.
• Rear coil springs provide approximately 2" of rear lift height over stock for a leveled front-to-rear stance.
• Rear 2.5 Series shocks support 1-3" of rear lift.
• These systems must be used with aftermarket upper control arms - the included ICON tubular Delta Joint UCAs are required for proper geometry. Do not install front coilovers with factory UCAs.
• An adjustable rear track bar is recommended (but not required) to realign the rear axle after installation.
• A 700 lb/in Expedition Coil option is available separately for heavier-equipped vehicles running winches, steel bumpers, or heavy accessories.
• Rear shock shaft protection is strongly recommended. ICON Part #56100 Shock Shin Guards are available separately due to the vulnerable rear shock shaft position on this platform.
• A Bump Stop Spacer Kit is available as an add-on if additional coilover threads are needed beyond the maximum recommendation.
• All shocks are fully serviceable. Ships in multiple boxes.

Features

• 2.5 Series Extended Travel front coilovers with internal reservoir deliver vehicle-specifically tuned damping and ICON-engineered coil springs for superior ride quality and feel throughout the range of travel
• Adjustable front lift height from 0-3.5" via threaded coilover body allows precise ride height tuning for desired wheel, tire, and stance
• Extended Travel coilover length unlocks increased front droop travel when paired with ICON UCAs, maximizing articulation and wheel contact on uneven off-road terrain
• Tubular Delta Joint upper control arms constructed from CNC-bent 1026 DOM steel - significantly stronger than OE arms - with built-in caster correction to restore proper front-end alignment geometry after lift
• ICON Delta Joint (U.S. Pat. 10,731,700) replaces the factory ball joint with a sealed, greaseable, high-angle joint combining the articulation of a uniball with the durability and corrosion resistance of a traditional ball joint
• 2.5 Aluminum Series Remote Reservoir rear shocks deliver superior rear damping performance - the remote reservoir increases shock oil volume and heat dissipation capacity for fade-resistant performance during extended off-road use
• ICON Bump Zone technology built into the rear shocks creates an additional 20% of damping force in the final 2" of compression travel, preventing harsh bottom-outs on big hits
• Tubular steel rear lower trailing arm kit replaces the OE lower links with stronger, adjustable units featuring multi-durometer bushings and pinion angle adjustment for optimized driveline geometry after lift
• ICON 2" rear coil springs provide a level front-to-rear stance and improved rear ride quality and wheel travel over the factory spring rate
• CAD-plated 2.5" coilover body with 7/8" shaft and 7/8" rear shock shafts resist corrosion and surface wear in wet and off-road environments
• FK Rod End bearings throughout the coilover and UCA deliver extended longevity and minimal deflection for precise suspension function
• 100% bolt-on system - no cutting or welding required for installation
• All shocks are 100% rebuildable and revalveable for long-term serviceability

Product Description

The ICON K53064T is the Stage 4 complete suspension system for the 2010-2024 Toyota 4Runner and 2010-2014 Toyota FJ Cruiser, featuring tubular steel upper control arms with Delta Joints. It represents the most comprehensive ICON suspension package for these platforms that uses the tubular UCA option (as opposed to the billet aluminum UCAs in the K53064 billet variant). The Stage 4 designation means this kit includes every major suspension component front and rear: extended travel 2.5 Series front coilovers, tubular Delta Joint UCAs, tubular lower trailing arms with pinion angle adjustment, 2" rear coil springs, and critically - the upgrade that separates Stage 4 from Stage 3 - 2.5 Series Remote Reservoir rear shocks with ICON's Bump Zone technology.

The front system centers on ICON's Extended Travel 2.5 Series coilovers (Part #58647), which pair an internal reservoir for heat management with ICON-engineered springs and a height-adjustable body spanning 0-3.5" of front lift. These coilovers are specifically designed to be used with ICON's tubular upper control arms (Part #58451DJ), whose increased arm length unlocks the coilover's full droop travel potential. The tubular UCAs are constructed from CNC-bent 1026 DOM steel and feature built-in caster correction and ICON's patented Delta Joint - a sealed, greaseable high-angle ball joint that matches uniball articulation while providing far better corrosion resistance and longevity for daily-driven applications.

The rear of the K53064T is equally comprehensive. The ICON 2.5 VS Remote Reservoir rear shocks (Part #57810P) are a significant step up from internal reservoir designs - the external remote reservoir dramatically increases oil volume and heat dissipation, preventing damper fade during hard off-road use. ICON's Bump Zone technology in these shocks builds a 20% increase in damping force over the final 2" of compression travel, delivering a controlled, progressive response on large impacts rather than a jarring bottom-out. The tubular lower trailing arms (Part #54000T) replace the OE links with significantly stronger adjustable units, and the 2" rear coil springs (Part #52700) deliver a level stance and improved rear wheel travel. KDSS-equipped vehicles are compatible with this system but require the addition of ICON's rear adjustable track bar Part #54200, sold separately.
