The early Bronco gave enthusiasts the ability to hit tough trails and stow more gear than the popular Jeep CJ-5 and travel in more comfortable style than the Scout. Just under 240,000 Broncos were sold over its production lifespan, and today the classic 4x4 is still highly sought after and far more expensive than its original price tag. The Bronco offered a suspension design very different from its competitors, a design that worked well off-road. The Pony's advanced front-coil-spring and radius-arm suspension was a first for an American-made 4x4. The Bronco turned into a very capable off-road vehicle when the factory optional Traction-Lok was fitted in the stout Ford 9-inch rear axle and limited-slip front differentials.
