The WH all terrain Rock Crawler coils tackle everything from the extreme conditions found in racing the Mexican 1000 to the boulder strewn trails from coast to coast and they are well suited to get you to the mall and back in your daily driver. The all terrain Rock Crawlers are built by design to be the perfect balance of comfort and durability. They have established a proven track record in both the on and off-road environments.
WH All Terrain Coil Springs are designed to give your 78-79 full size Bronco 4 inches of lift. Will also fit 66-79 Ford F100 and F150 trucks.
When rock crawling was beginning to grow in popularity, most of the Bronco coil springs on the market where a linear rate design with very heavy spring rates. The bar size was so large that the springs barely fit the coil cups. What you had was a stiff, non-flexible coil with a ride that would jar the fillings out of your teeth. It became obvious to us that we needed something different, so we designed and developed the ground breaking Rock Crawler coil line. At that time, the Rock Crawlers were the softest coil you could buy for the EB. These days you can get coils so soft that you can't hardly go around a street corner without body roll that makes your Bronco resemble a boat in the water. In contrast, the Rock Crawler coils are completely compatible with daily driving and off-road terrain from coast to coast. Since their introduction, we have received overwhelming positive feedback from Rock Crawler users. The 4" Rock Crawler coils are available in Red, Blue, and Black.
