Description PSW-26 this is the standard size of the boat seat suspension – air ride boat seat base, with the optimal ratio of control – the tension of the spring of the air shock absorber, the adjustment of the pressure (speed) of its rebound and the possibility of changing the static position of the shock absorber (boat seat pedestal stiffness). Allows you to make your own individual settings to achieve maximum comfort and safety. In our opinion, it will ideally fit for a boats 4.6-5.2m (15-17′) size. To adjust the pressure in the air chamber of the shock absorber, we recommend using a pump for bicycle forks. Available to order in black and white colors.
