Skyjacker 66-76 Ford F100 / 76-79 F150 / 78-79 Bronco 4WD 4in Front Dual Rate Coil Springs

Known for their phenomenal spring ride performance, Skyjacker's precision engineering gives you all the vigorous off-road handling needed while providing the smooth street riding characteristics that you demand. Skyjacker specifically engineered a progressive variable rate coil spring, distinctively a 2-stage dual rate long travel coil. Spring rate progression is from a first Flex Rate to a second Ride Rate. First Flex Rate stage of coil spring delivers a comfortable ride with ability to flex / expand during full articulation. This keeps coil springs seated at upper coil mount and tires in contact with terrain. Second Ride Rate stage of coil spring engages after compression past the First Flex Rate. The process starts with SAE9254 spring steel material, an advanced method of shot peening and a presetting process. Each coil spring is blasted (shot peen) with hard steel pellets at very high velocities. Shot peening compresses the surface of the steel thereby increasing the tensile strength of the spring. Compressing the spring completely down to where the coils touch (solid height) is preset. This takes any fatigue or stress off the spring and eliminates sagging. Every coil spring has endured a cycle test to assure the very best in quality. A baked on powder coat provides an extremely durable protective barrier to prevent corrosion. 4in.COILS 69-79F150/78-79 BRO

Enhance your vehicle's off-road and street performance with the Skyjacker 66-76 Ford F100, 76-79 F150, and 78-79 Bronco 4WD front dual rate coil springs. Crafted from high-quality SAE9254 spring steel, these springs feature a progressive two-stage dual rate design that provides a comfortable ride while maintaining excellent articulation during off-road excursions. The first Flex Rate offers a supple, flexible response for smooth street riding, ensuring that tires stay in contact with uneven terrain. As the coil compresses past the initial Flex Rate, the Ride Rate engages, providing additional support for challenging off-road conditions. This dual-stage setup optimizes handling and ride quality across diverse driving environments. Each coil spring undergoes rigorous shot peening with high-velocity steel pellets, which increases tensile strength and reduces the risk of fatigue or sagging. The presetting process ensures the springs are compressed to the solid height, eliminating stress and enhancing durability. Additionally, the baked-on powder coat finish offers superior corrosion resistance, extending the lifespan of the springs. Designed for direct bolt-on installation, these springs are engineered to preserve OEM suspension geometry and allow full articulation during suspension cycling. Whether you're upgrading for off-road adventures or improving daily driving comfort, these springs deliver reliable performance and impressive ride quality. Suitable for multiple Ford models from the mid-1970s to late 1970s, the Skyjacker coil springs are a durable and straightforward suspension upgrade for enthusiasts seeking enhanced handling and ride comfort.
