Off-road suspension technology has progressed dramatically over the past few years. Advancements in shock design and manufacturing have made superior Nitrogen-filled shocks more affordable and accessible. If you own a desert truck, rock crawler, a sand rail, or even a lifted street-pounder, chances are you’re running nitrogen filled shocks. Many of these nitrogen-filled shocks are equipped with a shrader valve for adjustment and refilling. Power Tank now offers a convenient Shock Filler Kit to easily fill and tune your shocks to the proper pressure.  At the racecourse, if a quick shot of nitrogen is needed, the Power Tank Shock Filler Kit is lightweight and easy to carry.  Despite its small size one NIT-0300 can inflate (20) shocks before refilling and unlike CO2, an N2 bottle can be topped off with the included refill kit.
