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.
