Superlift K184FX 4" Dual Rate Coil Suspension Lift Kit with Fox 2.0 Reservoir Shocks

The Superlift K184FX is a complete 4-inch dual rate coil spring suspension lift kit paired with Fox 2.0 Reservoir shocks, engineered specifically for the 4-door Jeep Wrangler JL Unlimited. This kit delivers a full 4 inches of front lift and 3.5 inches of rear lift for a level, aggressive stance — all without cutting or drilling.

At the heart of this kit are Superlift's location-specific dual rate coil springs, a first-of-its-kind design for the JL platform. Through rigorous testing, Superlift's engineers determined that a single spring rate cannot be used interchangeably side to side. Each spring transitions between two rate ranges, delivering a smooth, composed ride on pavement while providing the flexibility and durability needed for serious off-road use.

The included Fox 2.0 Reservoir shocks are matched to the spring rates and allow maximum extension travel without driveshaft bind, keeping the suspension performing optimally in all conditions. Compression stop spacers are also included to prevent tire contact during full compression, protecting both the tires and body panels.

• Location-specific dual rate coil springs (front and rear)
