Every AST damper is a monotube: nothing inside can aerate or foam, which AST say keeps the valving responsive.

5100 Street, inverted (AST ACU)

The 5100 Street kit with inverted monotube dampers, adjustable for rebound damping and ride height. The front dampers are coilovers; at the rear the spring and damper stay separate, as the car was built. Springs come in the kit, which works with the car's original top mounts. AST fix the rear spring rate for each car. The rebound adjuster has 12 positions, and the dampers can be rebuilt.

AST part number: ACU-M5002S
