These coil springs provide a 4-inch lift, delivering enhanced ground clearance for improved off-road capability while maintaining on-road ride quality.

Key Features:

• Variable rate spring design provides progressive resistance for better handling and load management
• 4-inch front lift height for improved approach angles and clearance for larger tires
• Application-specific engineering for JL 4-door Rubicon diesel models ensures proper load capacity
• Manufactured from high-quality steel with Skyjacker's durable finish to resist corrosion
• Designed to work with factory shock absorbers or upgraded aftermarket shocks
• Maintains proper suspension geometry for reduced wear on steering and drivetrain components

Skyjacker Suspension has been a trusted name in lift kits and suspension components for decades. These variable rate coils compress progressively, offering a softer ride over small bumps while providing firmer support under heavy loads or during aggressive off-road driving. The diesel-specific spring rates account for the additional weight of the diesel powertrain compared to gasoline models.
