Construction & Design

Crafted from high-grade steel, these coil springs feature a precision dual rate design that balances stiffness and flexibility. The dual rate technology provides a softer initial spring rate for smooth, comfortable daily driving and a firmer secondary rate that activates under heavy loads or off-road conditions, delivering the support needed for challenging terrain. This design minimizes harshness on pavement while maximizing off-road performance.

Superlift applies a corrosion-resistant powder coat finish to protect the springs from rust and environmental wear, ensuring long-lasting durability. Each spring is manufactured to exacting standards to maintain proper ride height and suspension geometry, preserving the vehicle’s handling characteristics and safety.

Installation of the Superlift Dual Rate Rear Coil Springs is straightforward for experienced mechanics and knowledgeable off-road enthusiasts. These springs are direct replacements for the factory rear coils on compatible Jeep models, requiring no major modifications. Professional installation is recommended to ensure proper fitment, alignment, and optimal suspension performance.

Fitment includes 2005–2010 Jeep Grand Cherokee, 2007–2018 Jeep Wrangler, and 2018–2026 Jeep Gladiator models equipped with gas engines only. These springs are not compatible with diesel-powered vehicles or Mojave editions. Always verify your vehicle’s model year and engine type before purchase to ensure proper fitment.
