The features included in individual models can differ from those shown

with low frequency suspension. Suited for medium and heavy-duty tractors. This vibration-optimized air suspension is perfectly suited for use in heavy vehicles and tractos with axle and cabin suspensions. Because these vehicles have a low natural frequency, GRAMMER developed a low frequency suspension. The benefits: the low frequency suspension absorbs vertical vibrations and jolts to prevent a resonant build-up that could otherwise lead to critical states. This meets a decisive criterion: the lower the seat suspension's natural frequency, the greater the suspension comfort for the driver.
