Skyjacker J40FS Softride Leaf Spring 3.5-4 Inch Lift Single

The Skyjacker J40FS Softride leaf spring delivers 3.5 to 4 inches of lift with a engineered design focused on ride quality and durability. This single leaf spring assembly is manufactured from premium American steel and features Skyjacker's proprietary Softride technology for enhanced performance both on and off-road.

Advanced Manufacturing Process:

• Shot-peened construction compresses steel surfaces with high-velocity hard steel pellets to increase tensile strength
• Shot-peening process maximizes wheel travel and ride quality while extending spring life
• Full-length leaf tapering distributes loads evenly and increases flex at the ends
• Tapered design reduces leaf-to-leaf contact damage and binding

Superior Design Features:

• Bolt-style spring clips eliminate friction for smoother operation
• Premium American steel construction ensures consistent quality and strength
• Engineered to maintain ride comfort without sacrificing load capacity
• Designed for maximum articulation and travel in demanding conditions

Skyjacker Softride springs represent a significant upgrade over standard cinch-clip designs that bind and create friction points. The combination of advanced metallurgy, precision manufacturing, and thoughtful engineering makes this leaf spring an excellent choice for truck and SUV owners seeking reliable lift with improved ride characteristics.
