55-12000 Spring Rockers, Other for Early Bronco
This patented product was designed to relieve the bind in the leaf springs caused by artictulation of the rear end. They greatly increase articulation but because the rear springs have a sway bar effect they also increase body roll. Most of the body roll can be nulled out by stiffer shocks. The spring rockers come with the U-bolts, bolts and nuts needed to install them. They have greaseable and replaceable bronze bushings.
