 Extra bushing overlap for improved side load management
 Specific wiper seal and air sleeve lubrication reduce friction 
 External rebound, low-speed and high-speed compression adjustment
 Climb mode to reduce suspension movements during climbs
 Includes (2) air spring volume spacers  
 Mounting hardware sold separately (spherical bearings reduce friction on the shock during side loads for improved small bump sensitivity, optional on widths up to 22mm)
