Skyjacker Suspension FR84S 4 Inch Softride Rear Leaf Spring Kit

The Skyjacker FR84S Softride leaf spring delivers 4 inches of lift for 2008+ Ford Super Duty trucks, combining enhanced ride quality with proven durability. Engineered specifically for rear axle applications, this spring kit provides the perfect balance between load-carrying capacity and off-road flexibility.

Advanced Manufacturing Process:

• Constructed from premium American steel for maximum strength and longevity
• Shot-peened with high-velocity steel pellets to compress the surface and increase tensile strength
• Full-length leaf tapering distributes loads evenly and reduces inter-leaf friction
• Bolt-style spring clips eliminate binding and friction found in traditional cinch-style designs

Performance Benefits:

• Maximizes wheel travel without compromising spring life
• Enhanced flex at leaf ends improves articulation on uneven terrain
• Smoother ride quality compared to conventional leaf spring designs
• Increased ground clearance for larger tires and improved off-road capability

Skyjacker's Softride technology represents a significant advancement over standard leaf springs, with engineering refinements that reduce leaf-on-leaf wear while maintaining the load capacity required for work truck applications. The result is a spring that performs better and lasts longer in demanding conditions.
