2007–2018 Jeep Wrangler JK / Jeep Wrangler JK Unlimited

24015

Overview:

The ICON 4.5-inch Dual-Rate Spring Kit is engineered specifically for the rear suspension of Jeep Wrangler JK models from 2007 through 2018. 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.

With 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.

Key Features:

The ICON 4.5-inch Dual-Rate Rear Coil Springs combine advanced engineering with durable materials to enhance your Jeep’s suspension system. Key features include:

• 4.5-inch rear lift height over stock for improved ground clearance and tire fitment
• Dual-rate coil design providing a smooth ride on pavement and firm support off-road
• Increased wheel travel when used with ICON shocks for enhanced suspension articulation
• Durable semi-gloss black powder coat finish for superior corrosion resistance
• Tested under ICON’s rigorous “ICON 1K” off-road validation program for strength and durability
• 100% bolt-on installation with no cutting or modifications required
• Lifetime warranty against sagging and breakage for long-term peace of mind

Construction & Design:

Manufactured from high-quality spring steel, ICON’s dual-rate coil springs are precision-engineered to deliver consistent performance and durability. 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.

The 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. Each spring is rigorously tested to meet ICON’s high standards for off-road performance and reliability.

Installation & Fitment:

The ICON 4.5-inch Dual-Rate Rear Coil Spring Kit is a direct bolt-on upgrade for Jeep Wrangler JK and JK Unlimited models from 2007 to 2018. 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.

Note that ICON’s advertised lift height is based on a typical Jeep JK equipped with heavier accessories such as rear bumpers and spare tires. Vehicles with stock weight may experience slightly higher lift heights.

• Pair of 4.5-inch dual-rate rear coil springs

It is perfect for enthusiasts who want to fit larger tires and improve ground clearance without compromising ride quality. Whether tackling rugged trails or cruising city streets, these springs provide a balanced and durable solution for lifted Jeep Wranglers.
