ICON Vehicle Dynamics V.S. 2.5 Series remote reservoir rear coilover shocks with CDCV are an incredible 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 Control Valves are included for precisely dialing in your suspension performance. CDCV controls fluid flow under compression, allowing you to achieve the perfect tune whether driving on the street, slow-crawling through the rocks or mobbing across the desert at full throttle. These rear coilovers are mounted in a shaft up orientation and 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. This shaft up orientation also 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. When paired with ICON 2.5 Series front coilovers vehicle control will be balanced front to rear, resulting in the best overall driving experience for your Ford Bronco.
