ICON Vehicle Dynamics V.S. 2.5 Series coilover shocks are an incredible upgrade for the front end of 2007-2021 Toyota Tundra equipped with a 6" lift suspension system. These full length coilovers are specifically designed for use with the ProComp 6" lift suspension system, but may also be compatible with kits from other manufacturers, and eliminates the top mount spacer commonly paired with the OE coilovers with these types of suspension systems. ICON’s Vehicle-specific valving provides a sport tuned feel on and off-road while lift height adjustability allows the fine tunings of vehicle stance. The larger 2.5” shock body and increased piston area over stock components and application specific length to maximize wheel travel provide 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 2.0 Aluminum Series or 2.5 Series rear shocks vehicle control will be balanced front to rear, resulting in the best overall driving experience for your Toyota.
