AST 5100 / 5200 / 5300 series

All AST and Moton dampers are monotube in design. Oil and gas are separated which offers a larger oil capacity and main piston when compared to twin tube. This combines to improve response and thermal resistance whilst preventing cavitation (aeration of the oil). Weight of the units is reduced through having less parts and the ability to use aluminium as damper bodies.

Each AST and Moton kit is specified bespoke to the car and driver, with the dampers being rebuildable for years to come this ensures long term ownership.

Please note some of the pictures may be generic.
