1 Leaf-spring suspension

The leaf spring is the oldest and simplest suspension. Several long, thin steel leaves are bound together in a pack by clamps. One end of the pack is connected to the vehicle's frame vis a bushing. The other end uses a shackle that can move for and aft. Combined with the flexing of the leaf pack itself, that provides the suspension movement and cushions the ride.

Most modern pickup trucks still use this setup for their rear suspension because of its simplicity and durability. The Chevrolet video from the 1930s shows how the suspension works and outlines its drawbacks for passenger car use.
