All Terrain 4" Coil Springs – Pair | 78-79 Ford Bronco, 66-79 F100/F150 4WD

Proven Ride Quality. Trail-Tested. Street-Approved.

Our 4" All Terrain Coil Springs are built for Full-Size 78-79 Broncos and 66-79 Ford F100/F150 4x4 trucks that see real use—on the street, on the trail, and everywhere in between. From the extreme conditions of racing the Mexican 1000 to boulder-strewn trails coast to coast, these coils have earned a proven reputation for dependable on- and off-road performance while still driving comfortably day to day.

In the past, Ford Bronco and truck coil springs were often overly stiff linear-rate designs with heavy spring rates and oversized bar diameters. The result was a harsh ride, limited flex, and suspension that barely worked off pavement. That didn’t cut it. The All Terrain Coil Spring line was engineered to fix those problems by delivering the right balance of flex and control.

These coils are tuned to absorb bumps without introducing sloppy body roll. They’re compliant enough to work off-road, yet firm enough to stay stable at highway speeds. Daily driving, rock crawling, or long road trips—they simply work.

Pro Tip: These coils springs provide approximately 4" of lift over stock. This amount of lift can vary depending on your rig's configuration and how worn out your original springs are. Sold as a pair.
