Product Description

The Skyjacker F746S Softride front leaf spring is an engineered lift solution tailor-made for 1965-1979 4WD Ford F-250 (High/Low Boy) and 1979 F-350 trucks equipped with engines ranging from 3.9 L to 7.5 L. Constructed of American-made steel and individually shot-peened, this 6-leaf pack offers exceptional tensile strength, fatigue resistance, and optimal wheel travel without degradation. With a progressive spring design and bolt-style clips, it minimizes binding and provides a smoother ride under load.

This spring achieves a 4-6" front lift depending on the specific truck setup, helping restore classic stance or accommodate larger tires up to 35". Its 3" width, 7½" free arch, and offset center pin ensure correct installation and alignment (short side forward). Sold individually, two units are required for a complete front lift - bushings (Skyjacker SE70F) and U-bolts are not included. After installation, professional alignment is strongly recommended to meet factory specs, especially when combined with Skyjacker's matching shock kits.
