Designed for drivers who demand a perfect balance between on-road comfort and off-road capability, these coil springs provide a substantial 4.5-inch lift over stock height. This lift not only enhances the vehicle’s stance but also allows for the installation of larger tires and increased wheel travel, especially when paired with ICON shocks.\u003c\/p\u003e\u003cp\u003eWith a dual-rate design, these springs deliver a softer initial compression for smooth daily driving and a firmer secondary rate that activates during heavier compression. This ensures excellent bottoming resistance and superior performance on rugged terrain. Backed by ICON’s lifetime guarantee against sagging and breakage, these springs offer long-lasting reliability and confidence for Jeep enthusiasts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe ICON 4.5-inch Dual-Rate Rear Coil Springs combine advanced engineering with durable materials to enhance your Jeep’s suspension system.

The dual-rate design means the springs have two distinct compression rates: a softer initial rate for comfort during normal driving and a firmer secondary rate that engages under heavier loads or rough terrain. This design improves ride quality without sacrificing off-road capability or suspension travel.\u003c\/p\u003e\u003cp\u003eThe springs are finished with a robust semi-gloss black powder coat that protects against rust and corrosion, ensuring they maintain their strength and appearance over time.

Installation is straightforward and requires no cutting, welding, or additional modifications. For optimal performance and increased wheel travel, it is recommended to pair these springs with ICON shocks designed for the same lift height.\u003c\/p\u003e\u003cp\u003eNote that ICON’s advertised lift height is based on a typical Jeep JK equipped with heavier accessories such as rear bumpers and spare tires.
