Skyjacker 4" 99-UP SUPERDUTY DIESEL

Starting with American steel, Skyjacker's Softride leaf springs are built to give your 2000-2005 Ford Excursion, or 1999-2004 F-250/F-350 Super Duty, a noticeable improvement in ride quality and capability. The key to their performance lies in the shot-peening process, where hard steel pellets are fired at high velocity. This compresses the surface of the steel, significantly increasing the spring's tensile strength. Without this step, achieving maximum wheel travel and a comfortable ride would mean sacrificing the spring's lifespan.

Beyond the material treatment, Skyjacker uses bolt-style spring clips instead of the more common cinch-style. Cinch clips can bind and create friction between the spring leaves, which hurts ride quality and can lead to premature wear. The bolt-style clips eliminate this friction. Furthermore, these Softride springs feature a taper that runs the entire length of each leaf, allowing for more flex at the ends. This design distributes loads more evenly across a larger area, reducing the chance of one leaf digging into the one above it, contributing to a smoother, more controlled ride, especially when you're looking to lift your vehicle by 4 inches.

This set is designed to provide a 4-inch lift, giving you the clearance needed for larger tires and improved off-road performance. When installing, ensure you follow the manufacturer's instructions for proper mounting and torque specifications to get the most out of these well-built springs.
