Construction & Design:

These coil springs are manufactured from premium high-strength alloy steel, providing superior durability and resistance to sagging or fracturing compared to standard springs. The dual-rate design allows the springs to offer a softer initial rate for comfort and a firmer secondary rate for load support and articulation. This engineering ensures the coil remains seated in the spring bucket even at full droop, preventing coil misalignment during extreme suspension travel.

The springs are finished with a robust powder coating that protects against rust and corrosion, extending the lifespan of the components in harsh off-road environments. Each spring is precisely matched to the OEM spring rate, ensuring that the vehicle maintains its intended ride quality and handling characteristics while benefiting from increased lift and articulation.

Installation & Fitment:

Installation of the Skyjacker Long Travel Rear Coil Springs is straightforward for experienced mechanics or off-road enthusiasts familiar with suspension upgrades. These springs are designed as direct replacements for the factory rear coils on compatible Jeep Wrangler Unlimited and Grand Cherokee models, requiring no major modifications. Proper installation ensures optimal suspension geometry and lift height.

It is recommended to have the installation performed by a qualified technician or at a professional shop to guarantee correct fitment and alignment. After installation, a wheel alignment is advised to maintain proper handling and tire wear.
