Springs: steel only. One coil and /or leaf spring per wheel only. One additional spring allowed on pull bar or lift bar, may be progressive. any coil spring must be at least 4.5 inches O.D. no torsion bars or air bags.
Shocks: One Steel non adjustable unaltered shock per wheel. One additional shock allowed on rear suspension. No bumpers or stops. No threaded body, front coil over, air, or remote resevoir shocks. No Screader valves. Front half may be shielded.
