iACT Suspension
This is not a mountain sled suspension but we think it’s worth mentioning. The iACT Suspension provides riders with instant and interactive on-the-fly control of the Fox Zero iQS gas shocks. The suspension is operated by your thumb using a button on the left side of the handlebars. The button is wired directly to both ski shocks and the rear track shock, letting the rider instantly switch between three compression settings (soft, medium, firm) to change the ride in different and changing conditions.
