Product Description

The ICON K53172T Stage 2 suspension kit is a comprehensive lift solution for 2003-2009 Lexus GX470 4WD -- offering adjustable ride height from stock up to 3.5" lift. This kit replaces the factory suspension (including rear air system) with robust coil springs, reservoir shocks, and upgraded control arms designed for improved articulation, suspension geometry, and reliability. The coil-over shocks feature a 2.5" body for increased fluid capacity and durability under demanding on- and off-road use.

Out-of-the-box, the front coil springs use a standard spring rate of 650 lb/in, which balances ride comfort and load-bearing capacity. For heavier builds or greater load capacity, an optional 700 lb/in spring set is available. The rear coil conversion replaces the factory air bags with steel springs and aluminum reservoir shocks, improving long-term reliability and simplifying maintenance. With all components bolt-on and no frame cutting required, this kit is ideal for GX470 owners seeking a durable, lifted suspension setup for larger tires, enhanced off-road capability, or improved on-road ride dynamics.
