Skyjacker 66-77 Ford Bronco 4WD 5in Front Dual Rate Coil Springs

This product includes a pair of Skyjacker 5-inch front dual rate coil springs, designed specifically for 1966-1977 Ford Bronco 4WD models. These aren't your average coil springs; they feature a unique two-stage, dual-rate design that Skyjacker calls a progressive variable rate system. This means the spring behaves differently depending on how much it's compressed, giving you the best of both worlds for off-road adventures and daily driving.

The first stage, or Flex Rate, allows the spring to comfortably flex and expand, keeping your tires on the ground during full articulation and ensuring the spring stays seated. Once compressed past this point, the second stage, the Ride Rate, engages. This advanced design uses SAE 9254 spring steel, which is then shot peened with hard steel pellets to increase its tensile strength. The springs are also preset to their solid height, which removes stress and prevents sagging over time. A baked-on powder coat finish adds a durable barrier against corrosion, keeping your springs looking good and performing well.

These coil springs are engineered to maintain proper OEM suspension geometry and are a direct, bolt-on replacement, making installation straightforward. You can expect improved off-road handling and a more comfortable ride on the street.
