Lift and Level Your 2024-2026 Lexus GX550 with the ICON 58790 VS 2.5 Series Remote Reservoir Front Coilover Kit
The ICON 58790 is a VS 2.5 Series remote reservoir front coilover kit engineered specifically for the 2024-2026 Lexus GX550. It provides 1.25 to 3 inches of lift height adjustability, allowing the GX550 to run larger wheel and tire combinations while improving suspension travel and off-road capability beyond the OEM setup.
The 2.5-inch diameter shock bodies are CAD plated for corrosion resistance and feature vehicle-specific valving developed for the GX550 platform. A remote reservoir significantly increases shock oil volume and heat dissipation to maintain consistent damping performance under hard use. ICON's CDXS compression damping adjustment allows independent tuning of high-speed and low-speed compression forces, giving drivers precise control over on-road handling and off-road aggressiveness. All CNC machined components use 6061 aircraft-grade aluminum construction. The kit is fully rebuildable and revalveable for long-term serviceability.

Frequently Asked Questions
What is the ICON 58790?
The ICON 58790 is a VS 2.5 Series remote reservoir front coilover kit for the 2024-2026 Lexus GX550. It provides 1.25 to 3 inches of lift adjustability, features ICON CDXS compression damping adjustment, and uses 2.5-inch diameter shock bodies with remote reservoirs for increased thermal capacity and consistent damping performance.
How much lift does the ICON 58790 provide on the GX550?
The ICON 58790 provides between 1.25 and 3 inches of front lift height adjustability. The actual installed lift height depends on the spring perch position selected during installation and the vehicle's current suspension load and leveling condition.
What tires can I run with the ICON 58790 on my GX550?
ICON states that 34-inch tires such as a 285/75R18 or 295/70R18 can be fit with the 58790 installed on an 18x9 wheel with 40mm offset. Larger tires may fit with fender trimming or additional modifications. Tire fitment also depends on wheel offset and backspace.
What is CDXS damping and how does it work on the 58790?
CDXS stands for Compression Damping Dual Speed with external adjustment. It provides two independent adjustment circuits: one for high-speed compression (controls large suspension inputs like impacts and drops) and one for low-speed compression (controls body roll, dive, and squat). Each circuit is adjusted separately with external knobs on the shock body, allowing the driver to tune the coilover for both on-road comfort and off-road performance without a full rebuild.
Is the ICON 58790 rebuildable?
Yes. All ICON VS 2.5 Series coilovers are fully rebuildable and revalveable. ICON offers rebuild services and replacement seals, bushings, and shafts. Rebuilding and revalving the shocks allows long-term cost savings versus replacement and lets you retune the valving if your use case changes over time.
Does the ICON 58790 require additional parts to complete the front suspension lift?
For maximum wheel travel and to eliminate binding at the new ride height, ICON recommends pairing the 58790 with an ICON front differential drop kit and upper control arms. The differential drop compensates for the CV axle angle change at lift height. ICON upper control arms restore proper caster and alignment geometry after the lift is installed.
What wheel specs does ICON recommend with the 58790 on the GX550?
ICON recommends an 18x9 wheel with 6.6 inches of backspace and 40mm offset as the primary aftermarket fitment recommendation. A 17x8.5 wheel with 6.32 inches of backspace at 40mm offset is also listed as compatible. OEM wheels and tires also fit the 58790 installation.
Is the ICON 58790 covered under warranty?
ICON Vehicle Dynamics products are backed by a limited lifetime warranty against defects in materials and workmanship for the original purchaser. Warranty claims are handled directly through ICON Vehicle Dynamics. Damage from improper installation, misuse, or modification outside of ICON specifications is not covered.
Installation Instructions
- Safely raise and support the front of the vehicle on jack stands. Remove the front wheels to expose the suspension assembly.
- Disconnect the front sway bar end links and any brake line or sensor brackets attached to the OEM strut or shock assembly.
- Support the lower control arm with a floor jack to relieve spring tension before disconnecting the OEM strut or coilover assembly.
- Remove the OEM front strut or shock assembly per the factory service procedure for the GX550.
- Assemble the ICON 58790 coilover per the included instruction sheet, setting the spring perch to the desired lift height before installation.
- Install the 58790 into the vehicle, torquing the upper mount and lower bolt to ICON-specified torque values.
- Mount the remote reservoir to the included bracket and route the reservoir hose away from heat sources and moving components.
- Reconnect all brake line brackets, ABS sensor harnesses, and sway bar end links.
- Reinstall wheels, lower vehicle, and bounce suspension several times before performing a professional alignment. A full 4-wheel alignment is required after installation.
- Set CDXS damping adjusters to ICON's recommended baseline settings and road-test before fine-tuning to preference.
