Skyjacker Suspension J40R Softride Rear Leaf Springs 3.5-4 Inch Lift

The Skyjacker J40R Softride rear leaf springs deliver 3.5 to 4 inches of lift for 1976-1986 Jeep CJ models. Sold as a pair, these replacement springs are engineered to provide enhanced ride quality and increased ground clearance without compromising durability.

Key Features:

• Constructed from premium American steel for maximum strength and longevity
• Shot-peened individual leafs compressed with high-velocity steel pellets to increase tensile strength
• Full-length leaf tapering distributes loads evenly and increases flex at the ends for improved articulation
• Bolt-style spring clips eliminate friction and binding common with cinch-style clips
• Engineered for maximum wheel travel and superior ride quality
• Reduces leaf-on-leaf wear and prevents digging between spring layers

Skyjacker's Softride technology combines advanced manufacturing techniques with precision engineering to create leaf springs that outlast and outperform standard replacements. The shot-peening process is essential for achieving the optimal balance between flexibility and load-carrying capacity, ensuring these springs maintain their performance characteristics over years of demanding use.
