The included ICON billet aluminum upper control arm kit is designed to improve the overall performance of the GX550 with corrected front-end geometry, increased on-vehicle camber and caster adjustment, and improved suspension component clearance. Additionally, replacing the OE ball joint with the all-new, serviceable, and rebuildable ICON Delta Joint PRO allows for full bump and droop travel of the front suspension while eliminating bind. The dual-rate rear coil design provides a softer ride height spring rate with a firmer overload rate that combine to deliver on-road comfort with excellent bottoming resistance and superior off-road performance. 2” of rear lift height over stock allows a for level stance front to rear. The ICON Billet Adjustable Rear Track Bar helps re-center the rear axle and double adjuster rod end threads allow easy “on-vehicle” fine adjustment of track bar length without requiring removal or disassembly of the track bar. ICON 2.0 Aluminum Series internal reservoir rear shocks utilize a vehicle-specific valving that balances the performance of the truck from front to rear. The ICON Vehicle Dynamics 2024 Lexus GX550 Stage 3 suspension system is an excellent choice for those drivers looking to enhance the capabilities of their pickup on the road as well as in the dirt.
