The ICON Attitude Adjustment Collar (AAC) is an industry first, patent pending multi-height coil spring collar that works in conjunction with a top load shim that can be configured in five unique ways to yield .5” to 2.25” of front lift height over stock. Taking the front end dimensions of the "Gen 2" Raptor into account, the collar and shim design of this leveling system achieves this range of lift height while keeping the OE shock in the ride zone, maintaining factory ride quality. Other options on the market achieve lift height solely through coil preload, which places the shock in the rebound zone at ride height and drastically impacts ride quality and performance. Installation of this leveling system requires no disassembly of the shock, making it a simple and straightforward process as opposed to other options currently available. CNC machined 6061 billet aluminum construction and a black anodized finish mean this product can stand up to the test of time in the harshest on and off-road conditions. Backed by ICON’s limited lifetime warranty, the ICON Vehicle Dynamics Attitude Adjustment Collar is the best leveling solution on the market for the 2017-2020 Ford Raptor.
