King Shocks 2.0 DIA. Internal Reservoir Rear Shock, 2.5-5in Lift - Single

King Air Shocks are built from the highest quality materials available. They provide a compact and lightweight option when used in the appropriate application. Air shocks ride on the pressurized gas charge inside (nitrogen). All air shocks are limited in their use by the physical properties of nitrogen gas. Nitrogen expands when it gets hot and contracts when it cools. In a lightweight rock crawler that only travels a few hundred yards during a full day of competition, this is not a problem. If you plan on running on the trail or the street for any length of time it becomes an issue.

When shocks work, they create heat. The heat causes the gas inside an air shock to expand which then extends the shock and changes the damping, it gets stiff. The same thing happens in reverse when the gas inside cools. You could start out on your favorite trail under sunny skies but as you gained elevation and the air got colder, your ride height could be much lower. You would get hung up easier because of the lower ride height. If you are driving a competition only rig and are looking to save weight above all else, air shocks may be the right shock for you. If you plan on driving on the street or running trails King Shocks has a complete product line of coilover and bypass shocks to choose from that will give you the most versatile performance for your rig.
