2-Pack 5.5 Inch Gas Lift Cylinders

This set includes two replacement gas lift cylinders designed to restore height adjustment on sinking office chairs. Each cylinder fits most executive, salon, work, and rolling stool models. The universal sizing allows a single purchase to service multiple seats or provide a spare. Buyers needing a single cylinder or a different stroke length cannot use this pack.

1000lbs Heavy-Duty Sustained Support

The piston is rated for a maximum load of 1000lbs, maintaining consistent lift force throughout daily use. Hydraulic pneumatic operation delivers smooth, noiseless 360 degree rotation without pressure drop over time. The cylinder holds position reliably from the minimum 11.8 inch length to the fully extended 17.4 inch length. Chairs exceeding the rated capacity or requiring a longer stroke will not be supported.

5.5 Inch Adjustable Stroke Range

The cylinder offers an adjustable travel of 5.5 inches between the compressed height of 11.8 inches and the extended height of 17.4 inches. This specific stroke determines whether the seat height range matches the user’s desk and body dimensions. Installation requires no additional screws. Any chair needing a shorter or longer travel distance will not work with this cylinder.
