ICON 2007+ Toyota FJ / 2003+ Toyota 4Runner Rear Air Bump Kit

56104 Overview
ICON Vehicle Dynamics now offers a bolt-in hydraulic bump stop Kit for the 2007-2014 Toyota FJ Cruiser AND 2003-2024 4Runner. This kit reduces rear-end “kick” and helps to improve the overall off-road performance of the vehicle. The OEM rubber bumpstops have a limited energy absorption capacity that is released rather uncontrollably upon rebound, resulting in a harsh ride and ill-handling vehicle in rough terrain. The ICON hydraulic bump stops are velocity sensitive which means that the amount of energy absorbed increases the faster they are engaged, so those harsh g-outs and square edges are less likely to interrupt your off-road adventures. Vehicles equipped with the ICON hydraulic bumpstop kit will have an increased bottom-out resistance over stock, as well as an improved drivability off-road. This kit installs easily inside the coil, and the bumpstops are fully rebuildable with the ability to be tuned for a custom ride. With a simple installation, proven effectiveness, and no loss in travel there is no reason not to bolt up the ICON Vehicle Dynamics hydraulic bumpstop kit to your ride and experience the difference.
The 4-link brackets, upper links, and lower links are sold separately, allowing the 4-link system to be customized for your specific Ford Super Duty year range.
