- Brand / Part #: Skyjacker F840S
Upgrade the front suspension of your Ford F-250 with the Skyjacker Softride Front Leaf Spring, Part Number F840S. Designed as a progressive multi-leaf pack, this spring provides approximately 3 inches of lift while supporting improved wheel travel, ride quality, and suspension durability. It is engineered for select Ford F-250 applications from 1980 through 1986 and 1997 through 1998, making it a dependable solution for refreshed or upgraded suspension systems.
Skyjacker Softride springs are manufactured using American steel, with each individual leaf shot-peened using high-velocity steel pellets. This process compresses the surface of the steel to increase tensile strength and help the spring withstand demanding suspension loads over time. The leafs taper along their full length to promote greater flex near the ends, distribute loads across a broader area, and reduce the possibility of one leaf digging into the leaf above it.
The F840S also uses bolt-style spring clips to help eliminate the binding and friction commonly associated with traditional bend-style clips. This design supports smoother leaf movement and contributes to the spring’s overall ride performance. Whether used for off-road capability, load support, or a suspension restoration, the Skyjacker Softride F840S delivers purpose-built performance for compatible Ford F-250 trucks. Professional installation is recommended, and fitment should be confirmed before ordering.
