AST 1-Way 4100

The 4100 Series shocks introduce high performance monotube technology at prices competitive with twin tube insert coilover kits. They include purpose built strut and shock bodies, shortened from stock lengths. All kits come with anodized aluminum adjusters that stay on the shock; no need to keep your pockets full of tools to make quick adjustments.
