ICON Vehicle Dynamics V.S. 2.5 Series remote reservoir rear coilover shocks with CDEV are the ideal upgrade for the rear end of the 2021-UP Ford Bronco. These adjustable coilovers allow up to 2-3” of rear lift height adjustability on 4-door Broncos without the Sasquatch package or 1.25-2.25” of rear lift over stock 4-door Sasquatch equipped Broncos, allowing the use of larger, more aggressive wheel and tire combinations. ICON’s Vehicle-specific shock length and valving along with the larger 2.5” shock body and increased piston area over stock components yield the maximum travel possible along with superior ride quality and suspension performance both on- and off-road. Reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. ICON's exclusive Compression Damping Electronic Valve (CDEV) are included to allow for lightning fast, precise electronic shock tuning, on-the-fly, at any speed and in any terrain. Focus on driving and let ICON Intelligent Control (IIC) read the terrain and make near-instant adjustments via the CDEV at each individual shock. Control the system wirelessly through the IIC app on your phone and once configured the system functions without driver input. These rear coilovers feature unique ICON engineered progressive triple rate coil springs, allowing for softer spring rate at ride height that ramps up as the coil compresses for improved bottom out resistance. Their shaft up orientation requires the reservoir hose to be routed along the rear lower links so ICON offers hose bracket options for the OE or ICON tubular links while ICON billet links incorporate this bracketry into their design. ICON 2.5 Series front coilovers with CDEV and matching IIC module are required for installation but vehicle control will be actively balanced front to rear, resulting in the best overall driving experience for your Ford Bronco.
