FLEX A is equipped with a new feature “Hydraulic Bump Stopper (H.B.S.)” which has been tested and proven effective in the world’s harshest motorsports including the World Rally Championship and European Rally Championship. When a lowered vehicle goes over big bumps, urethane or rubber bump stopper often causes a big upward jolt and/or rebound and can disturb controllability. On FLEX A, H.B.S., mounted inside the shock absorber, effectively generates damping force near and/or at full-bump, to absorb big impact smoothly. Comfortable rides in vehicles even at full occupancy will revolutionize the industry.
