Product Description
ICON Vehicle Dynamics 0-3.5" Stage 4 Suspension | Billet (Toyota 4Runner 2010+)
ICON’s 2010-UP Toyota 4Runner 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, 2” rear coil springs, and a 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.
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.
- KDSS Equipped vehicles require 54200 Rear Adjustable Track Bar
