Key Features

These coil springs incorporate advanced technology and materials to ensure durability and performance:

• 2.5-inch front dual rate long travel coil springs designed for enhanced suspension articulation
• Progressive variable rate with two distinct stages: Flex Rate and Ride Rate
• First Flex Rate stage allows comfortable ride and full suspension droop without losing tire contact
• Second Ride Rate stage engages under compression for added support and stability
• Constructed from 5160H chromium alloy steel for superior strength and resilience
• Shot peened surface to increase tensile strength and reduce fatigue
• Preset solid height to eliminate sagging and maintain consistent performance
• Baked-on powder coat finish for long-lasting corrosion resistance
• Cycle tested to ensure quality and durability under demanding conditions

Construction & Design

Skyjacker’s coil springs begin with premium 5160H chromium alloy steel, known for its toughness and flexibility. The manufacturing process includes shot peening, where the spring surface is bombarded with high-velocity steel pellets. This compresses the steel surface, enhancing tensile strength and extending spring life by reducing fatigue.

Each spring is preset to its solid height, meaning the coils are compressed to the point where they touch before installation. This presetting process removes internal stresses and prevents sagging over time, ensuring consistent ride height and performance. The durable powder coat finish protects against rust and corrosion, making these springs reliable in harsh environments.

Installation & Fitment

Designed as a direct fit for the front suspension of 2021–2024 Jeep Wrangler models with the 6.4L 392 engine, these coil springs install with standard suspension tools and procedures. No major modifications are required, making them a straightforward upgrade for experienced DIYers or professional installers. Proper installation ensures optimal suspension travel and ride quality.
