ICON's 2003-2009 Lexus GX470 Stage 4 suspension system provides a significant increase to the on and off-road performance of the vehicle. This system includes the components featured in the Stage 3 setup - extended travel 2.5 Series coilover shocks, an ICON billet aluminum upper control arm kit or Tubular upper control arm, 2" rear coil springs, and either a tubular steel or billet aluminum rear lower link arm kit - but sees the addition of 2.5 Series Remote Reservoir rear shocks for balanced damping characteristics front to rear. The remote reservoir design allows for increased shock oil volume and enhanced cooling so that the rear of the vehicle can work harder for longer durations without noticeable "fade" occurring. The 2.5 Series Remote Reservoir rear shocks also feature ICON's "Bump Zone" technology which significantly increases damping ability in the last 2" of compression travel, preventing harsh bottom-out sensation and giving the vehicle a much more controlled ride quality over varying terrain.
KEY FEATURES:
- Increased wheel travel and ride quality over stock
- Vehicle specific tuned front and rear shocks for superior shock damping and control
- Adjustable coilovers provide 0-3.5" of front lift height
- Extended Travel coilovers matched with ICON UCA provides increased front droop travel
- Billet Aluminum rear lower links offer on vehicle pinion angle adjustment
- 6061 aircraft grade aluminum CNC machined components
- Corrosion resistant CAD plated coilover shock body with 7/8" shaft
- FK Rod End bearings for extended longevity and minimal deflection
- 2.5 Series remote reservoir rear shocks with 7/8" shafts
- Bolt-on system means no cutting or welding necessary for install
DELTA JOINT OVERVIEW:
This system features upper control arms with ICON's patent pending Delta Joint. The Delta Joint is a heavy-duty high angle ball joint that combines the durability of a ball joint with the performance characteristics of a traditional uniball. While the industry standard uniball does a great job of allowing the control arms of a vehicle to articulate with little bind, they do have an inherent weakness that leaves more to be desired when used in a daily driven application - exposure to the elements. The Delta Joint features a zinc plated housing providing the first layer of corrosion resistance, while a tough grease seal keeps potentially harmful elements out of the inner workings of the joint. Metal on metal construction and a greaseable design increase the longevity of the Delta Joint while at the same time allowing for noise-free operation. What makes the Delta Joint unique is that it brings the best of both worlds to ICON upper control arms with features that make it more robust than a uniball, and at the same time capable of greater angularity than a typical ball joint
