Leaf springs are pretty common on custom 4x4s, even though coil and coilover combinations are becoming quite popular. Coils and coilovers can be tempting, but don't sell the old-fashioned leaf-spring ...

We ain't like them fancy magazines what get all uppity with them coilovers and chain-link suspensions. If two pairs of leaf springs were good enough for those WWII GIs, they're good enough for us.

Rassini’s 1+C Hybrid leaf spring features a single steel parabolic main plate and a flat glass fiber composite helper plate to provide suspension on the rear wheels of the Ford F-150 pickup truck.
