ICON 54102 Billet Rear Upper Link Kit for Toyota Tundra, Sequoia, Tacoma, Land Cruiser, 4Runner and Lexus GX550

ICON’s billet aluminum rear upper link arms for the 2022-2026 Toyota Tundra, 2023-2026 Toyota Sequoia, 2024-2026 Toyota Tacoma, 2024-2026 Toyota Land Cruiser 250 Series, 2025-2026 Toyota 4Runner, and 2024-2026 Lexus GX550 are a significant upgrade over the factory units due to increases in strength, adjustability, and performance. These links are made from CNC machined 6061 aluminum in-house and anodized for corrosion resistance, providing a major improvement over the construction of the stock units. This rear upper link arm kit features PTFE-lined FK rod ends for increased suspension articulation, reduced deflection, and on-vehicle link arm length adjustability using ICON’s double adjuster system. Additionally, multi durometer bushings are installed that allow for noise free operation and maximum angularity without the need for periodic greasing and/or other maintenance. The quality rod ends and bushings featured in these link arms allow the vehicle’s suspension to function as intended, without the bushing bind that limits the vehicle in stock form. After the design phase was completed ICON engineers put these parts through the “ICON1K” real-world test cycle for a final stamp of approval. ICON billet trailing arms are light, strong, and engineered to improve off-road ride quality. Built with CNC machined 6061 aluminum, they feature PTFE-lined rod ends, replaceable nylon rock sliders for protection, and on-vehicle adjustment. APPLICATION NOTE #141: Tundra/Sequoia equipped with Automatic Leveling Headlights or Load-Leveling Rear Height Control Air Suspension part # 55153 is also required

• On vehicle adjustment for different ride heights and pinion angles using ICON's Double Adjuster System
• Maintenance free, dual durometer bushings for maximum angularity and noise isolation
• Covered by ICON’s Limited Lifetime Warranty
• Large FK Bearing JMX16T PTFE-lined rod ends
• CNC machined 6061 aluminum construction
• Vehicle specific design

Upgrade rear suspension performance with the ICON 54102 billet rear upper link kit, engineered for select 2022-2026 Toyota Tundra, 2023-2026 Toyota Sequoia, 2024-2026 Toyota Tacoma, 2024-2026 Toyota Land Cruiser 250 Series, 2025-2026 Toyota 4Runner, and 2024-2026 Lexus GX550 applications. Compared with factory link arms, this vehicle-specific kit improves strength, adjustability, suspension articulation, and off-road ride quality. Each link is CNC machined from 6061 aluminum and anodized to provide durable corrosion resistance in demanding driving conditions.
The ICON 54102 kit uses ICON’s Double Adjuster System for on-vehicle adjustment of link length, ride height, and pinion angle. Large FK JMX16T PTFE-lined rod ends help reduce deflection while allowing increased suspension articulation. Multi-durometer, maintenance-free bushings provide maximum angularity and noise isolation without periodic greasing, helping the suspension operate without the binding commonly associated with factory components. Replaceable nylon rock sliders add protection during off-road use while keeping the links light and strong.
ICON engineers validated the design through the ICON1K real-world test cycle, and the kit is backed by ICON’s Limited Lifetime Warranty. For Toyota Tundra and Sequoia vehicles equipped with automatic leveling headlights or load-leveling rear height control air suspension, application note #141 requires ICON part 55153 in addition to this kit. Verify vehicle configuration and suspension compatibility before installation. The ICON 54102 rear upper link kit is designed for enthusiasts seeking durable construction, precise adjustment, and improved suspension function on and off the road.
