{"product_id":"icon-4-5-stage-8-suspension-system-k64548","title":"ICON 4.5\" Stage 8 Suspension System K64548","description":"\u003cdiv\u003eGAP carries the Icon 4.5\" Stage 8 Suspension System K64548 that allows you to fit larger, more aggressive wheel and tire combinations. This Stage 8 system is ideal for on-road and towing use, as well as job site duty washboard gravel roads, and aggressive off-road use. Icon's 4.5\" Stage 8 System offers 4.5\" lift coil springs optimized for trucks equipped with the Powerstroke engine with a dual-rate design. The dual-rate coil springs allow for a softer initial rate for superb on-road comfort and a firmer secondary rate that increases during compression to resist bottoming out and enhance off-road performance. \n\u003cbr\u003e\n\u003cbr\u003eICON Vehicle Dynamics 4-Link kit further enhances driving dynamics by eliminating suspension bind commonly experienced with factory radius arms during articulation and allows on-vehicle caster angle adjustment. This \"freeing up\" of the front end and the ability of the 4-Link Kit to maintain positive caster through the range of travel equates to unequaled ride quality in every condition. The fabricated track bar drop bracket allows the axle to be properly centered under the truck and minimizes road feedback throughout the steering system.  This allows for improved on- and off-road manners thanks to the elimination of bump steer. The adjustable track bar allows for on-vehicle adjustment to fine-tune track alignment. This eliminates the deflective factory track bar bushings for an overall more rigid unit to enhance the vehicle's handling characteristics. \n\u003cbr\u003e\n\u003cbr\u003eICON's Centerline steering stabilizer kit features a 2.5 Aluminum Series shock absorber with a piggyback reservoir for improved steering damping. The ICON dual 2.0 steering stabilizers offer better control of undesirable steering feedback caused by larger tires while also increasing ground clearance. Heavy-duty fabricated 5\" rear blocks and U-bolt kit lift the rear of the truck and are designed to withstand heavy towing\/hauling duty as well as the strains of aggressive off-road use. ICON 2.5 Aluminum Series remote reservoir front and rear shocks with CDEV feature a vehicle-specific tune for improved vehicle handling and exceptional ride quality on- and off-road.\n\u003cbr\u003e\n\u003cbr\u003eThe remote reservoirs massively increase shock oil volume and heat dissipation surface area to deter overheating and cavitation under hard use, which can lead to damper fade. Focus on driving and let ICON Intelligent Control (IIC) read the terrain and make almost instant adjustments with the Compression Damping Electronic Valve (CDEV) at each shock. Control the system wirelessly through the IIC app on your Apple device and once configured the system functions without any driver input. \n\u003cbr\u003e\n\u003cbr\u003eThe included box kit comes with fabricated front sway bar drop brackets to prevent binding, heavy-duty aluminum bump stop spacers, and high-quality stainless steel extended brake lines. This suspension system features high-quality CNC machined, laser cut, and brake-formed parts and components. Icon has spent endless hours testing and tuning the suspension components and shock absorbers to make this lift kit a complete system.\n\u003cbr\u003e\n\u003cbr\u003e\u003ch5\u003e\u003cspan style=\"color: #e42626\"\u003eFeatures:\u003c\/span\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eHeavy-Duty Fabricated Rear Lift Blocks\u003c\/li\u003e\n\u003cli\u003eStainless Steel Braided Front Brake Lines\u003c\/li\u003e\n\u003cli\u003eShocks Are Fully Rebuildable \u0026amp; Re-Tunable\u003c\/li\u003e\n\u003cli\u003eLifetime Guarantee Against Coil Spring Breakage Or Sagging\u003c\/li\u003e\n\u003cli\u003eApproximately 50% Increased Front Wheel Travel Over Stock\u003c\/li\u003e\n\u003cli\u003eTrack Bar Drop Brackets Reduce Track Bar Angle \u0026amp; Corrects Bump Steer Geometry\u003c\/li\u003e\n\u003cli\u003eLifetime Guarantee Against ICON Fabricated Component Breakage Or Manufacturer Defect\u003c\/li\u003e\n\u003cli\u003eAdjustable Track Bar Allows Fine Tuning Of Track Alignment \u0026amp; Improves Handling Characteristics\u003c\/li\u003e\n\u003cli\u003e2.5 Aluminum Series Shocks Feature Corrosion-Resistant Hard Anodized Shock Bodies With 7\/8\" Shafts\u003c\/li\u003e\n\u003cli\u003eICON 2.5 Centerline Steering Stabilizer Kit With Piggyback Reservoir Offers Increased Steering Damping\u003c\/li\u003e\n\u003cli\u003eICON Dual Rate Coil Springs Deliver 4.5\" Of Front Lift With Exceptional Vehicle Control Over Varying Terrain\u003c\/li\u003e\n\u003cli\u003eRemote Reservoirs Maintain Cooler Operating Temperatures \u0026amp; Consistent Performance During Extended Off-Road Use\u003c\/li\u003e\n\u003cli\u003eICON 4-Link System Eliminates Binding During Articulation \u0026amp; Maintains Positive Caster Through The Entire Range Of Travel\u003c\/li\u003e\n\u003cli\u003eICON 2.5 Aluminum Series Remote Reservoir Shocks Feature Vehicle Specific Tune For Superior Performance \u0026amp; Ride Quality\u003c\/li\u003e\n\u003cli\u003eICON's CDE Valve Technology Allows For In-Vehicle Adjustment Of Compression Damping Settings \u0026amp; Active Adjustment Via The ICON Intelligent Control (IIC)\u003c\/li\u003e\n\u003cli\u003eICON Intelligent Control (IIC) Uses Onboard Sensors To Monitor G-forces \u0026amp; Movement Of Vehicle Chassis Along With User Defined Settings To Actively Make Near-Instantaneous Compression Damping Changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\u003cspan style=\"font-weight: bold; color: rgb(228, 38, 38);\"\u003eTire Fitment:\n\u003c\/span\u003e\u003cbr\u003e17\" x 8.5\" With 5\" Backspace \u0026amp; 6mm Offset\n\u003cbr\u003e18\" x 9\" With 5.25\" Backspace \u0026amp; 6mm Offset\n\u003cbr\u003e20\" x 9\" With 5.25\" Backspace \u0026amp; 6mm Offset\n\u003cbr\u003eTires: 37\" x 12.50\" (Larger tires may fit but fender trimming and modifications will be required.)\u003c\/div\u003e\n\u003cdiv data-hook=\"variant_changed__data\" data-contentsection=\"render_carb_restriction\"\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cspan style=\"color:#e42626\"\u003e\u003cstrong\u003eNote: \u003c\/strong\u003e\u003c\/span\u003e\n\u003cbr\u003eFor diesel applications only. \u003cbr\u003eFits single-rear-wheel models only. \u003cbr\u003eWill not fit F-350 Cab \u0026amp; Chassis models. \u003cbr\u003eLift heights based on 4WD crew cab diesel. \u003cbr\u003eAn iOS-operated device is required to run the ICON Intelligent Control App. \u003cbr\u003eTrucks equipped with Tremor package will have a front lift height of 3.5\" over stock. \u003cbr\u003eShocks are fully serviceable.
