Construction & Design

These coil springs are crafted from a higher strength alloy that provides superior resistance to sagging and fractures compared to standard springs. This robust material choice ensures the springs maintain their shape and performance over time, even under demanding off-road conditions. The powder coating applied to each spring enhances corrosion resistance, protecting the springs from rust and environmental damage while maintaining a clean, professional look.

The dual rate design incorporates two distinct spring rates within a single coil, allowing for a softer initial compression to absorb minor bumps and a firmer secondary rate to handle heavier loads and extreme articulation. This engineering approach results in a suspension that adapts dynamically to varying terrain and driving conditions, improving both comfort and control.

Installation & Fitment

Installation of the Skyjacker 3.5-inch Rear Dual Rate Long Travel Coil Springs is straightforward for experienced mechanics and off-road enthusiasts familiar with suspension upgrades. These springs are designed as direct replacements for the rear coils on Jeep Wrangler JK models from 2007 to 2018, requiring no major modifications or additional components. Proper installation ensures optimal spring positioning and suspension geometry, preserving factory ride height and handling characteristics.
