Overview

The Skyjacker Dual Rate Long Travel Coil Springs are engineered specifically for the rear suspension of Jeep Wrangler models from 2021 to 2024 equipped with either the 2.0L Turbo or the 6.4L 392 engine. Designed to provide a 4-inch lift, these coil springs enhance off-road capability while maintaining a comfortable ride on and off the pavement. Featuring a progressive two-stage dual rate design, they deliver superior articulation and improved suspension performance tailored to the Wrangler’s unique handling characteristics.

Ideal for Jeep enthusiasts seeking a balance between ride comfort and rugged off-road performance, these coil springs allow for increased suspension travel and tire contact with uneven terrain, making them a reliable upgrade for serious trail riders and daily drivers alike.

Key Features

Skyjacker’s innovative dual rate coil springs incorporate advanced engineering to optimize both comfort and articulation. Key features include:

• Progressive two-stage dual rate design for enhanced ride quality and suspension articulation
• First Flex Rate stage provides a comfortable ride and allows for increased suspension droop
• Second Ride Rate stage engages after compression beyond the flex rate for improved handling and support
• Side-specific rear coil springs engineered to match the Wrangler’s suspension geometry
• 4-inch lift height to improve ground clearance and accommodate larger tires
• Maintains coil spring seating in upper mounts during full articulation to keep tires in contact with terrain
• Durable construction designed to withstand off-road conditions and heavy use

Construction & Design

Skyjacker’s dual rate coil springs are crafted from high-quality steel alloys, precisely wound to deliver a progressive spring rate that adapts to varying terrain and driving conditions. The two-stage design starts with a softer flex rate to absorb minor bumps and allow suspension droop, enhancing articulation and traction. As the suspension compresses, the springs transition to a firmer ride rate, providing the necessary support to prevent bottoming out and maintain vehicle stability.

The side-specific design ensures that each coil spring complements the Wrangler’s rear suspension geometry, optimizing handling and ride comfort. The springs are finished with a corrosion-resistant coating to protect against rust and extend service life in harsh environments.

Installation & Fitment

These coil springs are designed for direct replacement on the rear suspension of 2021–2024 Jeep Wrangler 2.0L Turbo and 2023 Jeep Wrangler 6.4L 392 models. Installation typically requires standard suspension tools and moderate mechanical experience. No major modifications are necessary, but professional installation is recommended to ensure proper fitment and performance.

Once installed, the 4-inch lift improves ground clearance and suspension travel, allowing for better off-road articulation and tire clearance without compromising ride quality.
