All Terrain 3 1/2" Coil Springs – Pair | 1966-77 Ford Bronco
Proven Ride Quality. Trail-Tested. Street-Approved.
Back in the early days of off-roading, most of the Bronco coil springs on the market were a linear rate design with very heavy spring rates. This type of coil springs were stiff enough to rattle your teeth loose. Their oversized bar sizes were so large the springs barely fit the coil cups, and they provided barely enough flex to crawl a curb—let alone a trail. That didn’t sit right with us. So we went to work and built something better: the ground-breaking All Terrain Coil Spring line.
These 3.5" lift coils changed the game with a smoother ride, better flex, and real-world performance you can count on. They’re soft enough to soak up the bumps, but still firm enough to keep you from swaying like a sailboat on the street. In other words—they just work. Daily driving? Yep. Rock crawling? Absolutely. Coast-to-coast road trips? Bring it on.
