ICON Vehicle Dynamics V.S. 2.5 Series internal reservoir front coilover shocks are an incredible upgrade for the front end of the 2022-2023 Toyota Land Cruiser 300 Series. These adjustable coilovers allow up to 1-3* of lift height adjustability, 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. When paired with ICON 2.5 Aluminum Series rear shocks vehicle control will be balanced front to rear, resulting in the best overall driving experience for your Toyota Land Cruiser 300 Series. ICON*s Vehicle-specific shock length and valving along with the larger 2.5* shock body and increased piston area over stock yield the maximum travel possible along with superior ride quality and suspension performance both on- and off-road. APPLICATION NOTE #142: NOT COMPATIBLE WITH VEHICLES EQUIPPED WITH LOAD-LEVELING REAR HEIGHT CONTROL AIR SUSPENSION.
