Skyjacker Suspension JP40FS Softride Leaf Spring 3.5-4 Inch Lift

The Skyjacker JP40FS Softride leaf spring delivers 3.5 to 4 inches of lift height for enhanced ground clearance and off-road capability. Engineered with premium American steel, this single leaf spring provides exceptional durability and performance for demanding applications.

Advanced Manufacturing Process:

• Shot-peened construction compresses the steel surface with high-velocity hard steel pellets, significantly increasing tensile strength
• Full-length tapering design distributes loads evenly across the entire leaf surface, reducing stress concentration
• Bolt-style spring clips eliminate friction and binding common with traditional cinch-style bend clips

Performance Benefits:

• Maximum wheel travel without compromising spring longevity
• Enhanced flex at leaf ends for superior ride quality
• Reduced leaf-to-leaf friction prevents premature wear and digging
• Optimized load distribution for consistent performance under varying conditions

The Softride design philosophy combines metallurgical engineering with practical suspension geometry to deliver a spring that balances lift capability with ride comfort. Ideal for trucks and SUVs requiring increased ground clearance while maintaining daily drivability.
