Fox Racing Shox Factory Race Series 1.5 Zero QS Shocks

Fox Racing Shox offers Factory Race Series 1.5 Zero QS shocks for a variety of applications, including many Polaris, Lynx, and Ski-Doo snowmobiles from 2011 and up. These Quick Switch (QS) coil shocks are the next generation of lightweight mountain sled suspension technology. Ride harder in the backcountry with less fatigue without a compromise of durability—and experience a new sense of control on top of the snow due to less outboard weight. Fox's QS technology allows you to adjust the compression and rebound damping with ease to suit the conditions. Three positions keep the adjustment simple, so you focus on the ride instead of counting clicks. The rear track is also equipped with a lockout mode to prevent trenching the next time you get in the deep snow or climbing steep faces.

Fox designed the coil-sprung mountain shocks with two primary objectives: weight reduction and ride performance. They optimize the 1.5 Zero coil-sprung shocks through material reduction without a sacrifice of ride quality or structural integrity. Additionally, the coil springs were redesigned to retain the same spring rate but with fewer coils and built from a lighter steel alloy. The shocks maintain a linear feel regardless of temperature fluctuation, which keeps your sled setup quick and simple. The new coils result in a spring with the same performance at half the weight.

Fox's position-sensitive damping technology, with origins in desert truck racing, is now applied to the Factory Race Series coil-sprung shocks. Spiral grooves inside the shock allow the oil to flow around the main piston, reducing damping force in the ride zone for a plush feel. The bypass grooves terminate through the final 30 percent of the travel, forcing oil to only flow through the main piston and providing a significant increase of bottom-out resistance to cushion any hard hits. Maximize the power-to-weight ratio of your sled by bolting on Fox's new mountain shocks!
