Construction & Design

Superlift Dual Rate Coil Springs are crafted from premium-grade steel, engineered to withstand the rigors of off-road use while providing consistent performance over time. The dual rate design incorporates two distinct coil rates within a single spring, allowing for a softer initial compression for comfort and a firmer secondary rate for load support and stability. This innovative approach ensures that your Jeep maintains a balanced ride whether you’re navigating rocky trails or driving on pavement.

Each spring is precision wound and heat-treated to enhance strength and resist sagging, ensuring your lift height remains consistent throughout the life of the product. The springs are also coated with a durable finish to protect against corrosion and environmental damage.

While some suspension disassembly is required, the process is simplified by the precise fitment and engineering of the springs.
