The ICON Vehicle Dynamics Overland Series Rear Coil Spring Kit was developed for the expedition-style offroader who is loading down their vehicle with bumpers, winches, rooftop tents, and more. ICON engineers developed this multi-rate coil spring to provide compliant handling and the exceptional on and off-road ride quality you would expect from an ICON product. This coil spring kit will deliver 3 of lift in an unloaded vehicle, and 2 of lift when loaded down with a typical list of overland equipment. Designed by ICON and manufactured by Eibach, these springs are guaranteed for life not to sag or break.
