These are the Synergy Rear Coils that will work on both 2-door, as well as 4-door vehicles. These coil springs have been designed to offer premium off-road performance, yet suitable for street driving on the way to the trail. These springs feature a progressive wound construction that prevents the spring from coming unbound at suspension droop, and it also eliminates any unwanted clunking noises that are inherent on a lot of suspension lift kits.
These springs have been powder-coated black for maximum durability, and protect them against corrosion. Finally, these springs have been designed to achieve the desired lift height even with aftermarket rear bumpers, as well as tire carriers.
