Product Description

The Skyjacker FR74S Rear Softride Leaf Spring is engineered to raise the rear suspension of classic Ford F-250 4WD pickup trucks by approximately 4" compared to stock ride height. Built with Skyjacker's progressive Softride design and high-strength, shot-peened American steel, these springs help improve load support, ground clearance, and articulation while maintaining a smoother ride than stock leafs. Bolt-style clips minimize friction between leaves for better flex and longer life.

This direct-fit rear leaf spring fits 1966-1977 F-250 High Boy 4WD and 1978 F-250 Low Boy 4WD trucks. Sold individually, two FR74S springs are required for a complete rear suspension upgrade. Ideal for replacing worn factory leafs or completing a 4" lift setup on classic Ford trucks, these Softride leaf springs enhance capability both on- and off-road.
