Product Description

The Skyjacker FR904S Softride Leaf Spring is engineered to provide a 4-inch rear lift for 2009-2014 Ford F-150 4WD models. Constructed with American-made steel, this single leaf spring features a progressive multileaf pack design that enhances ride quality and articulation. The shot-peening process applied to each individual leaf increases tensile strength, ensuring durability and performance. The included axle shim corrects pinion angle, preventing driveline vibration and improving overall handling.

Designed to replace factory leaf springs, the FR904S offers a smoother, more controlled ride, especially when towing or off-roading. Its tapered leaf design reduces friction and spring wrap, common issues with traditional lift blocks. Installation is straightforward, utilizing factory mounting points, and the spring is sold individually. For optimal performance, it's recommended to replace both rear leaf springs simultaneously.
