The Stage 4 suspension system w/ tubular UCA for the 2010 + FJ Cruiser and 4Runner is an entire new level of suspension. Where the difference in this Stage 4 kit is going to be seen and felt is in the rear of the FJ/4Runner. The front suspension is the same as Stage's 2 and 3, but we add our ICON V.S. 2.5 rear remote reservoir shocks to the rear set up. Our rear springs in this system give the FJ Cruiser/4Runner 2" of lift, and the rear billet lower links help manage the rear axle to cycle smoothly with our bind. ICON's V.S. Series 2.5" Diameter Rear Reservoir Shocks make vast improvments compared to the first 3 systems for the people that use there vehicles in various offroad situations. These shocks are tuned specifically to give your FJ/4Runner a balanced and smooth ride quality and extended length shock cooling from the increased oil volume and remote reservoir. 57810 FJ/4Runner 2.5" rear shocks have a built in bump zone to increase your compression valving in the final two inches of compression travel, which prevents the harsh bottom out sensation and gives the vehicle a much more controlled ride quality.
• We recommend the use of our #56100 shock shin guards or a protective boot to reduce the chance of shock shaft damage. These shocks are located in a vulnerable position that allows debris to easily come in direct contact with the shock shaft.
