Springs and shocks are dirt-track parts... front springs are AFCO 700# 5" x 9.5" with threaded "weight-jacker" adjusters from speedway motors used for adjustable ride-height. Rear springs are Tru-Coil 175# 5.5" x 11" single-pigtails. Shocks are AFCOs for street-stock class. It rides a bit rough, but the handling is incredible!
