Setting up your suspension components requires both specific knowledge of the fork or shock, as well as a high pressure suspension pump. These compact pumps drive very high pressure at very low volume, and any model you use must be accurate. The Fox Racing Shox Factory High Pressure Shock Pump has long been a best selling model for three reasons. Number one is accuracy. Number two is ease of use. Number three is durability. Add in an easy to read 300psi analog dial gauge, a perfectly placed bleed port, swivel hose with easy-to-use Schrader valve interface, and impressive construction and you have the only suspension pump you'll ever need.
