Overview:

The Skyjacker Long Travel 4-inch Front Coil Spring Set is engineered specifically for Jeep Wrangler Unlimited models from 2007 to 2018 and Jeep Grand Cherokee models from 2005 to 2010. Designed to provide a reliable 4-inch lift, these dual-rate coil springs enhance off-road capability by maximizing suspension articulation while maintaining excellent ride quality on and off the trail. Ideal for enthusiasts seeking improved ground clearance and suspension travel without compromising daily drivability, this coil spring set offers a balanced upgrade that complements factory suspension geometry.

These springs maintain the coil securely in the bucket even at full droop, preventing coil misalignment and ensuring consistent performance during extreme articulation. Matched closely to the OEM spring rate, they deliver a smooth and controlled ride, making them suitable for both rugged terrain and street use.

Key Features:

Skyjacker’s Long Travel Front Coil Springs combine advanced engineering with durable materials to deliver dependable performance. Key features include:

• 4-inch front lift designed for Jeep Wrangler Unlimited and Grand Cherokee models
• Dual-rate coil design that maintains coil position at full droop for maximum articulation
• Higher strength alloy construction to resist sagging and fractures over time
• Powder-coated finish for enhanced corrosion resistance and long-lasting durability

Construction & Design:

These coil springs are crafted from a high-strength alloy that surpasses the durability of many competitors. The material choice prevents common issues such as sagging and coil fractures, which can degrade suspension performance over time. The dual-rate design features variable coil spacing that allows the springs to compress progressively, providing a softer initial ride and firmer support under heavy loads or extreme articulation.

The powder-coated finish not only enhances corrosion resistance but also contributes to a clean, professional appearance that withstands harsh environmental conditions. Precision engineering ensures the springs fit perfectly within the factory coil buckets, maintaining proper suspension geometry and alignment.

Installation & Fitment:

Installation of the Skyjacker Long Travel Front Coil Springs is straightforward for experienced mechanics and off-road enthusiasts familiar with suspension work. These springs are designed as a direct fit replacement for the front coils on compatible Jeep Wrangler Unlimited and Grand Cherokee models, requiring no major modifications. Proper installation maintains OEM suspension geometry and ride characteristics while delivering the intended 4-inch lift and improved articulation.

For best results, it is recommended to have the installation performed by a professional or with the appropriate tools and knowledge of coil spring replacement procedures. Alignment after installation is advised to ensure optimal handling and tire wear.
