New Gas Ski Shock for Arctic Cat M7 EFI, all versions. Fits 2005 to 2006 models.

Standard hydraulic shocks absorbers use air and oil to cushion the stroke of the shock absorber. A gas shock replaces the air in the shock with pressurized nitrogen gas. The nitrogen gas keeps it cooler than a hydraulic shock. Also when a hydraulic shock is used on rough surfaces (ie washboard) the hydraulic oil may foam thus reducing its effectiveness. The nitrogen in gas shocks helps to eliminate the potential for oil to foam.

An additional benefit of a gas shock absorber is that it creates a mild boost in spring rate. Replaces OEM #'s 1703-764, 1703-783, 2703-554 Shock Length Open: 17-1/2" Shock Length Closed 11-3/4" Bottom Eye Diameter: 14.5 mm Top Eye Diameter: 14.5 mm.
