New Feature Hydraulic Bump Stopper (H.B.S.) Provides Comfortable Ride in ALL Seats Even at Full-Load!
FLEX A is equipped with new feature "Hydraulic Bump Stopper (H.B.S.)" which has been tested and proven effective in the world's harshest motorsports including 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 ride in the 3rd seats of minivans can revolutionize the industry.
