This coil-over conversion kit for 1970-72 A-body cars features Viking billet, double-adjustable coil over shocks and 175-lb. springs. Adjustable from 1" to 7" lower in the rear, the race quality shocks feature dual 19-click rebound and compression adjustment knobs providing a total of 361 possible dampening combinations, while the threaded pre-load collar will adjust ride height as well as make the spring stiffer or softer. The shock body is manufactured in high-quality billet aluminum and the surface features a sleek, clear anodized finish. Springs are cold-wound US spring steel that has been heat treated and shot-peened prior to being powder-coated in high-gloss silver.
