TOKICO Illumina Adjustable Series is a trendsetter of the shock absorber technology. Perhaps, the best among these is Tokico Illumina Gas Shock, which is renowned for its ease of adjustment and change in vehicle response. Tokico Illumina employs a specially calibrated orifice bypass system, which helps in achieving simultaneous adjustment of both compression and rebound. The adjustment range, with 5 separate positions available, is one of the hallmarks of Tokico Illumina. Position 1 is the softest, or lowest damping force, while position 5 is the stiffest.
