ICON Rear Dual Rate Spring Kit

2018–2023 Jeep Wrangler JL & Unlimited JL

22026

Overview:

The ICON Rear Dual Rate Spring Kit is engineered specifically for the 2018 to 2023 Jeep Wrangler JL and Unlimited JL models, delivering a precise 2.5-inch rear lift. Designed for Jeep enthusiasts who demand a balance of superior on-road comfort and rugged off-road capability, these coil springs enhance wheel travel and allow for larger tire fitment without compromising ride quality. ICON’s dual rate technology provides a softer initial spring rate for smooth daily driving and a firmer secondary rate that activates during compression, offering excellent bottoming resistance and improved off-road performance.

Built to complement ICON shocks, this spring kit increases rear wheel travel by 2 inches, improving articulation and traction over rough terrain. Whether you’re upgrading your Jeep for trail adventures or enhancing its stance and clearance, the ICON Rear Dual Rate Spring Kit delivers reliable performance backed by a lifetime guarantee against sagging and breakage.

Key Features:

Designed with precision and durability in mind, the ICON Rear Dual Rate Spring Kit offers the following key features:

• 2.5" rear lift height based on a factory 4-door Rubicon JL configuration
• Dual rate coil springs for a softer initial ride and firmer secondary rate under compression
• Increased rear wheel travel by 2" when paired with ICON shocks
• Supports tire sizes up to 35" stock, and up to 37" with optional bump stop spacer kit (PN: 22029)
• Lifetime warranty against sagging and breakage for long-term confidence
• 100% bolt-on installation with no cutting or welding required
• Includes swaybar links and bump stop spacers for a complete rear suspension upgrade
• Tested under ICON’s rigorous “ICON 1K” off-road validation program for strength and durability

Construction & Design:

ICON coil springs are manufactured from high-quality steel alloys engineered for strength and resilience in demanding off-road environments. The dual rate design incorporates two distinct spring rates within a single coil, allowing the suspension to adapt dynamically to varying terrain and load conditions. This design ensures a comfortable ride on pavement while providing progressive resistance to prevent bottoming out during heavy compression off-road.

Each spring is precision wound and heat-treated to maintain consistent performance and resist sagging over time. The kit’s components, including swaybar links and bump stop spacers, are designed to integrate seamlessly with the Jeep Wrangler JL’s factory suspension geometry, preserving handling characteristics and ride quality.

Installation & Fitment:

The ICON Rear Dual Rate Spring Kit is a direct bolt-on upgrade for 2018–2023 Jeep Wrangler JL and Unlimited JL models, including Sport, Sport S, Sahara, Rubicon, Willys, and special editions such as the 80th Anniversary, Freedom, Islander, High Altitude, High Tide, and Moab trims. Installation requires no cutting or welding and can be completed with basic hand tools by experienced enthusiasts or professional installers.

For optimal performance and increased wheel travel, pairing these springs with ICON shocks is recommended. Lift height may vary slightly depending on vehicle weight and accessory load, as ICON’s advertised lift is based on a typical Jeep JL equipped with heavier rear bumpers and spare tires.

What's Included:

• Rear dual rate coil springs (2.5" lift)
• Swaybar links
• Bump stop spacers
• Installation hardware and instructions

Ideal For:

This spring kit is ideal for Jeep Wrangler JL owners seeking a balanced suspension upgrade that enhances off-road capability without sacrificing daily driving comfort. It suits those who want to fit larger tires, improve ground clearance, and increase rear wheel articulation for trail performance. Perfect for off-road enthusiasts, weekend adventurers, and anyone looking to elevate their Jeep’s stance and suspension performance with a reliable, lifetime-backed product.
