    Overview

    ICON Vehicle Dynamics V.S. Series 2.5” coilover shocks are an incredible upgrade for the front-end of 2021-2026 Chevrolet Tahoe & Suburban/2021-2026 GMC Yukon & Yukon XL SUVs. Their longer length offers an increase in total front wheel travel compared to stock, for a total of 9” front wheel travel (a 20% increase over stock) while still being compatible with the stock front upper control arms. ICON’s Vehicle-specific valving provides a sport tuned feel on and off-road while 2.5-3.25” of front lift height adjustability allows the use of larger, more aggressive wheel and tire combinations. The larger 2.5” diameter shock body and increased piston area over stock components provides improved damping ability and outstanding ride characteristics across varying types of terrain. Remote 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. When paired with ICON rear 2.5 Series coilover shocks vehicle control will be balanced front to rear, resulting in the best overall driving experience for your GM SUV.
