K53173 - ICON Stage 3 Suspension System (03-09 GX470)

K53173 - ICON Stage 3 Suspension System for 2003-2009 Lexus GX470

Overview:

The ICON Stage 3 Suspension System for the 03-09 Lexus GX470 includes the components found in the Stage 2 system along with an ICON Rear Lower Link kit. Extended travel ICON 2.5 Series coilover shocks and a Delta Joint upper control arm kit provide a significant upgrade to the 4Runner’s front suspension. The rear of the vehicle is improved with our 2" lift coil springs, ICON 2.0 Aluminum Series shocks, and the additional rear lower links. ICON's CNC machined 6061 billet aluminum lower links are much stronger than the OE units,  can be easily adjusted on the truck for optimum pinion angle, and are protected by a machined nylon skid strip to help slide over rocks without damage to the link’s structure. On top of it all, these links have been designed to provide correct roll steer geometry for the best possible handling on and off-road.

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 greasable 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.

Tech Info:

• We recommend the use of our #56100 shock shin guards or a protective boot to reduce the chance of shock shaft damage.  These shocks are located in a vulnerable position that allows debris to easily come in direct contact with the shock shaft.
• GX470 models equipped with factory rear air ride suspension require ICON rear coil conversion kit (Part # 56110)
• KDSS Equipped vehicles require 54200 Rear Adjustable Track Bar.
