AST 4100 Series
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. They are single adjustable (rebound only) and can be custom valved for your application. 4100s use the same internals as our 4300 Competition shocks.
