ICON Vehicle Dynamics Stage 3 Suspension Kit with Tubular UCAs for Jeep Wrangler & Gladiator

Upgrade your 2018–2024 Jeep Wrangler JL, Unlimited JL, or Gladiator JT with the ICON Vehicle Dynamics Stage 3 suspension system, a comprehensive solution bridging high-speed desert running and technical rock crawling. This platform utilizes 2-inch diameter remote reservoir shock bodies to deliver advanced thermal management and piston area for precise damping control, paired with tubular upper control arms engineered to restore proper alignment geometry and eliminate factory bump steer variance.

• Remote Reservoir Shock Architecture: Features CNC 6061-T6 billet aluminum shock bodies in the front to house multi-stage internal valving. The enlarged reservoir separates oil from nitrogen to prevent cavitation during hard compression cycles, ensuring consistent feel over washboard sections or rapid descents where conventional monotubes degrade.
• Tubular UCA Design for Geometry Correction: Replaces cast OEM upper control arms with heavy-duty tube construction incorporating sealed spherical bearings. The updated kinematic design corrects the pinion angle and caster reduction inherent to lifted platforms, directly addressing common complaints regarding steering wander and toe-on variations.
• Lightweight, Corrosion-Rated Components: Machined aluminum shock housings reduce unsprung weight compared to heavier cast alternatives. Entire assemblies receive a durable powder-coat finish compatible with off-road chemicals, while fasteners utilize stainless steel grades to resist galvanic corrosion and seizure during trail recovery.
• Verified Fitment Specifications: Configured for 2018–2024 Jeep Wrangler and Gladiator platforms equipped with the standard 3.6L Pentastar V6 gasoline engine. Explicitly excludes diesel powertrain variants requiring higher-valved springs and modified shock stroke profiles.
• Predictable Lift Profile & Travel Management: Produces a controlled 2.5–3.0 inch stance depending on spring preload setup. Internal bump stops and spring rates are matched to the lift height to maintain optimal shock positioning within the frame rails, preventing piston-to-shock-body binding under maximum droop.
• Wheel Offset & Tire Clearance Standards: Optimal compatibility requires wheels with a +6mm offset / 5.25-inch backspace measurement to preserve hub-centric loading and inner fender clearance. Accommodates up to 35-inch tires with existing suspension routing; minor liner modification may be required for 37-inch tire installations.
• Limited Lifetime Manufacturing Warranty: Supported by ICON Vehicle Dynamics coverage against defects in manufacturing and material integrity for the original owner, reflecting industrial assembly tolerances and test-rig validation standards.

Critical Installation Notes: Professional mounting is essential. A four-wheel alignment must be performed immediately following installation to lock in corrected camber and toe settings. Due to the increased track width effect from arm offsets, an adjustable aftermarket track bar is highly recommended to recenter the front axle laterally and stabilize steering linkage dynamics.
