Skyjacker J40FSB 4-Inch Lift Softride Leaf Spring

The Skyjacker J40FSB Softride leaf spring delivers a 4-inch lift with superior ride quality and durability. Engineered with premium American steel, this single leaf spring is designed to provide maximum wheel travel while maintaining long-term performance in demanding off-road conditions.

Advanced Manufacturing Process:

• Shot-peened construction using high-velocity steel pellets to compress the surface and increase tensile strength
• Full-length leaf tapering distributes loads evenly and increases flex at the ends
• Bolt-style spring clips eliminate friction and binding found in traditional cinch-style designs
• Precision engineering reduces leaf-on-leaf digging for smoother operation

Key Benefits:

• Enhanced ride quality through improved flex characteristics
• Extended spring life due to shot-peening treatment
• Better load distribution across the entire leaf surface
• Reduced friction for consistent performance

Skyjacker Softride springs are built for enthusiasts who demand both lift capability and on-road comfort. The combination of American steel construction, advanced tapering design, and friction-reducing hardware makes this an ideal upgrade for trucks and SUVs requiring increased ground clearance without compromising ride quality.
