ICON Vehicle Dynamics V.S. 2.5 Series internal reservoir front coilover shocks are an incredible upgrade for the front end of the 2000-2006 Toyota Tundra and 2001-2007 Toyota Sequoia. These adjustable coilovers allow up 0-2.5” of lift height adjustability, allowing the use of larger, more aggressive wheel and tire combinations. ICON’s Vehicle-specific shock length and valving, their large 2.5” shock body with increased piston surface area over stock components, yield increased front wheel travel along with superior ride quality and suspension performance both on- and off-road. When paired with ICON 2.0 or 2.5 Aluminum Series rear shock absorbers vehicle control will be balanced front to rear, resulting in the best overall driving experience for your vehicle.
