1 0 Monotube Damper (www.mandoparts.com)

2 1 Mono Tube Damper Purpose Purpose Feature Feature Application (Domestic) Improvement of comfort and handling under various conditions Better ride & road-holding performance HyundaiSsangyong Genesis CoupeYF SONATAChairman-H (10MY) Separate oil and gas chamber by free piston - Good fade performance Light weight with less components High gas-pressure charge (app. 15~30bar) Stable damping force at any install conditions (Upright, sideways, upside-down) Gas Chamber (High Pressure) Free-floating Piston Base shell Base Shell Oil Inner Tube Oil Mono TubeTwin Tube Applicable for rear damper only Gas Chamber (Low pressure)

3 2 Twin TubeMono Tube Consists of an inner and outer tube : Gas charged in outer tube (Gas filling pressure: 3 Bar) Rebound damping force produced by piston valve Compression damping force produced by body valve Outer Tube Body Valve Oil Piston Valve Inner Tube Gas Chamber (Low Pressure) Rebound / Compression Oil Single Tube Mechanism Comparison Shock absorber trend Rebound / Compression Piston Valve Free-Floating Piston Gas Chamber (High Pressure) Consists of a single tube : Oil and High pressure gas chamber (30bar ) separated by free-floating piston Free-floating piston : Moves during rebound and compression stroke Rebound and compression damping force controlled by piston valve

4 3 Feature Description Feature Damping lag occurrence possible by oil cavitation due to pressure change ( Unbalanced R & H ) Damping Force No damping lag by oil cavitation due to separate oil/gas chamber 100Weight ratio80 ( 10 ~ 20% ↓ ) Variable ( Damping force cannot be retained in highly inclined conditions ) Packaging Variable ( Damping force retained even on highly inclined conditions ) Disadvantage of heat emission due to twin tube Durability Swift heat dissipation due to single tube design Normal response (OE-Spec) Ride & Handling Better response and road holding due to high pressure chamber Low pressure oil seal Major Component High pressure oil seal Free floating piston added Increased thickness for strength and controlled roughness of piston sliding part on outer tube → Higher cost compared to twin tube Performance Comparison Twin TubeMono Tube Damping lag Stroke Damping force Benefits Stroke
