Features

• Shot-peened with high-velocity steel pellets to compress the surface and increase tensile strength for maximum travel without sacrificing spring life
• Tapered leaf design distributes load more evenly across the entire spring length, reducing inter-leaf wear and increasing flex at the ends
• Bolt-style spring clips eliminate the friction and binding caused by cinch-style bend clips found on competing designs
• Teflon wear pads between leaves reduce inter-leaf friction for a smoother, more compliant ride on and off road
• Multi-leaf pack construction delivers GVW rating and load capacity equal to or greater than OEM springs
• Manufactured in the USA using high-quality American steel for consistent performance and long service life
• Black powder-coat finish provides corrosion resistance in harsh off-road and weather conditions

Product Description

The Skyjacker J40FS is a Softride Series front leaf spring delivering 3.5 to 4 inches of front lift for 1976-1983 Jeep CJ5, 1976-1986 Jeep CJ7, and 1981-1985 CJ8 Scrambler. Built from shot-peened American steel with a tapered multi-leaf design, it provides more aggressive lift than the J20FS while maintaining the same Softride hallmarks: even load distribution, reduced inter-leaf binding, and improved suspension travel without sacrificing spring life or load rating.

At this lift height, a Pitman arm and transfer case drop kit are recommended to preserve proper steering geometry and reduce driveline angles. Sold individually - two springs are required for a complete front installation. Spring bushing kit SE40J is required and sold separately. Optional U-bolt kit UCJF is also available for builds using OEM axle hardware.
