Rubicon Express Nitrogen Shock Charge Kit - Charge!Posted in How To: Suspension Brakes on July 1, 2009
High-end coilovers and other mono-tube shocks have never been shipped with the required Nitrogen, and charging these shocks as well as hydraulic bumpstops has always been expensive or just a hassle. In the past you had to either invest in a large nitrogen gas bottle, regulator, and a fill kit or you had to find and then haul your rig to a shop that would charge the shocks for you. Rubicon Express went to work whittling a billet aluminum solution to this common problem. The company came up with the nitrogen recharge kit (PN REC300).
The charge kit is a convenient size and simple to use. It only requires an 11/16-inch wrench to tighten the fitting to the Schrader valve on the shock or bumpstop. One disposable gas bottle fills four shocks or four large hydraulic bumpstops to 150 psi.
The disposable Nitrogen cylinders thread into the end of the unit and a pin inside pierces the top much like on a CO2-powered BB gun. One button fills the shock (FILL) and the other is used to release pressure (VENT) if you overcharge.
The kit includes the anodized billet charging unit complete with braided stainless line and a liquid-filled gauge, two Nitrogen cylinders, two spare O-rings, an adapter so the charging unit can be attached to a fullsize bottle, and it's all packed into a padded blow-molded plastic case.
