ICON 2024 GX550 1.25-3in Lift Stage 4 Suspension System w/ Tubular UCA

K53354T Overview
ICON Vehicle Dynamics 2024-2025 Lexus GX550 suspension systems are designed with maximum performance and the serious driver in mind. ICON engineers’ primary focus is to increase wheel travel and damping ability, which translates into outstanding vehicle control and ride quality both on- and off-road. The Stage 4 system includes vehicle-specific tuned 2.5 Series coilover shocks featuring remote reservoirs for exceptional cooling properties and ICON-engineered coil springs for superior vehicle “feel” through the range of travel. These coilovers are height adjustable from 1.25-3” of front lift height over stock, allowing the use of larger, more aggressive wheel and tire combinations. Remote reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. The combination of front differential drop brackets and ICON’s specifically designed coilover lengths maximizes the available front suspension travel and prevent CV bind. Additionally, polyurethane differential mounting bushings replace the soft OE bushings to help limit differential movement under load.
The 4-link brackets, upper links, and lower links are sold separately, allowing the 4-link system to be customized for your specific Ford Super Duty year range.
