The Stage 4 suspension system for the 2010 + FJ Cruiser/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 Piggyback Reservoir Shocks to the rear set up. Our rear springs in this system gives 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 Piggyback Shocks make vast improvements compared to the first 3 systems for the people that use there vehicles in various offroad situations.
These shocks are tuned specifically to give a balanced and smooth ride quality and extended length shock cooling from the increased oil volume and piggyback reservoir. 57710 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.
