Skyjacker Suspension YJ40RSB Softride Leaf Spring 4 Inch Lift

The Skyjacker Suspension YJ40RSB Softride leaf spring delivers a 4-inch lift with superior ride quality and durability. Engineered specifically for Jeep Wrangler YJ applications, this single leaf spring assembly combines American steel construction with advanced manufacturing techniques to provide exceptional performance both on and off-road.

Key Features:

• 4-inch lift height for improved ground clearance and aggressive stance
• Shot-peened steel construction increases tensile strength and spring longevity
• Full-length leaf tapering distributes loads evenly and increases flex at the ends
• Bolt-style spring clips eliminate friction and binding for smoother articulation
• 100% American steel construction ensures consistent quality and reliability
• Optimized leaf design maximizes wheel travel without sacrificing spring life

Skyjacker's proprietary shot-peening process bombards each leaf with hard steel pellets at high velocity, compressing the surface to dramatically increase strength. The tapered leaf design reduces stress concentration points and prevents individual leafs from digging into adjacent layers. Combined with friction-free bolt clips instead of traditional cinch-style clamps, the YJ40RSB delivers the smooth, controlled ride that made Softride springs an industry benchmark. Single spring sold individually.
