ICON K53184T Stage 4 Suspension 0-3.5" Tubular UCA Kit for 2010-2023 Lexus GX460

Vehicle Fitment

• 2010-2023 Lexus GX460 (Base, Premium, Luxury, Black Line Special Edition | 4.6L V8 | 4WD AWD)

Fitment Notes

• Does not fit the 2024+ Lexus GX550, which is a new platform requiring a dedicated kit.
• GX460 models equipped with factory rear air ride suspension require ICON Rear Coil Conversion Kit Part #56110, sold separately, before this system can be installed.
• Compatible with KDSS (Kinetic Dynamic Suspension System) equipped vehicles. Front sway bar relocation brackets included in the coilover kit are not used on KDSS-equipped vehicles. The included ICON adjustable rear track bar (Part #54200) ensures KDSS compatibility and corrects rear axle alignment after lift.
• Extended travel front coilovers must be used with the included ICON tubular upper control arms. Do not install extended travel coilovers with factory UCAs.
• Certain model years require trimming for proper front remote reservoir bracket fitment.
• Remote reservoir mounting brackets may interfere with aftermarket bumper mounts or windshield washer bottles - verify clearance before and after installation.
• 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 for a leveled front-to-rear stance.
• A 700 lb/in Expedition Coil option is available separately for heavier-equipped vehicles running winches, steel bumpers, or other 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.
• 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 outstanding ride quality and maximum front wheel travel on and off-road
• 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 tubular UCAs, maximizing articulation and wheel contact on uneven terrain
• Tubular Delta Joint upper control arms constructed from CNC-bent 1026 DOM steel with semi-gloss powder coat finish - 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 uniball-level articulation 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 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 large hits and giving the GX460 a much more controlled feel over rough terrain
• 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 and correct roll steer after lift
• ICON 2" rear coil springs provide ~2" of rear lift and improved rear ride quality for a level stance front to rear
• Included ICON adjustable rear track bar (Part #54200) ensures KDSS compatibility and corrects rear axle lateral alignment after lift - a GX460-specific inclusion critical for KDSS function
• 6061 aircraft-grade aluminum CNC machined coilover components with CAD-plated 2.5" body and 7/8" shaft for maximum corrosion resistance
• FK Rod End bearings throughout coilover and UCA deliver extended longevity and minimal deflection
• 100% bolt-on system - no cutting or welding required
• All shocks are 100% rebuildable and revalveable for long-term serviceability

Product Description

The ICON K53184T is the Stage 4 complete suspension system for the 2010-2023 Lexus GX460 with tubular steel upper control arms. It represents one of ICON's most comprehensive GX460 packages and includes every major suspension component front and rear: Extended Travel 2.5 Series front coilovers, tubular Delta Joint UCAs, tubular rear lower trailing arms with pinion angle adjustment, 2" rear coil springs, 2.5 Series Remote Reservoir rear shocks with Bump Zone technology, and the GX460-specific adjustable rear track bar for KDSS compatibility. The Stage 4 designation marks the point at which ICON upgrades the rear shock from the 2.0 Aluminum Series (used in Stages 1-3) to the full 2.5 Series Remote Reservoir design - matching the performance caliber of the front coilovers in a balanced, end-to-end system.

The 2.5 Series Remote Reservoir rear shocks (Part #57810P) are the defining upgrade in the Stage 4 package. Where internal reservoir shocks have a finite heat management capacity, the remote reservoir dramatically expands oil volume and cooling surface area, providing sustained, fade-resistant damping performance during hard off-road use where repeated shock strokes would otherwise heat up and degrade the feel of an internal reservoir unit. ICON's Bump Zone technology adds a final layer of control by progressively increasing damping force by 20% in the final 2" of compression travel - preventing the harsh bottom-out sensation that is common on heavily loaded or aggressively driven lifted GX460s. The tubular rear lower trailing arms (Part #54000T) replace the OE lower links with significantly stronger multi-durometer bushing units featuring on-vehicle pinion angle adjustment for correct driveline geometry after lift.

On the front, the K53184T's Extended Travel coilovers (Part #58647) pair with ICON's tubular DOM steel UCAs (Part #58451DJ) to maximize front droop travel and correct alignment geometry after the lift is installed. Built-in caster correction in the tubular UCAs helps keep tires wearing evenly and steering feeling precise at all lift heights, with the Delta Joint providing the high-angle, sealed, greaseable ball joint function needed for the coilover's full range of motion. Like all GX460 kits, the K53184T includes the ICON adjustable rear track bar (Part #54200), which is essential for KDSS-equipped GX460s to maintain proper axle alignment and preserve KDSS function. GX460s with factory rear air suspension require the ICON Rear Coil Conversion Kit (Part #56110, sold separately) before installation.
