Product Description

The Skyjacker FR84S 4" Rear Leaf Spring is engineered to lift the rear suspension of your Ford Super Duty truck, delivering improved ground clearance, towing capability, and a more aggressive stance. Designed with Skyjacker's Softride technology, this leaf spring uses a progressive multi-leaf pack with shot-peened steel construction for enhanced strength and flexibility. Bolt-style clips reduce friction between leaves, while the included rubber bushings help isolate vibration and road shock for a smoother ride.

This spring is a direct fit replacement for 2008-2016 Ford F-250 and F-350 Super Duty 4WD trucks needing a 4" rear lift. Sold individually, two FR84S springs are required for a complete rear lift installation. Whether you're replacing worn-out factory springs, leveling a lifted front end, or completing a full suspension upgrade, this Skyjacker leaf spring delivers rugged performance and long-lasting reliability.
