Powertank Nitrogen Shock Kit - Charging Your Own Rebuilable Shocks

Posted in How To on June 1, 2009

If you've got nitrogen-charged, rebuildable shocks on your truck or 4x4, then you might have experienced some sort of leak down in nitrogen pressure for one reason or another. Technically, rebuildable shocks are not supposed to leak, but over time seals or valves can let N can leak out, or incurred damage can necessitate a recharge.

And though you really are supposed to change shock dampening with shock valving, you can make minor adjustments manipulating the nitrogen pressure in the reservoir. Most shocks are recommended to run at around 200 psi, but we have seen guys run anywhere from 160 psi to 260 psi in their shocks.

But how do you even know what pressure levels you have in your shocks? Most good tire pressure gauges only go up to 100 psi-well below any reading that a properly-pressurized shock would give. And on top of that, what would you do to recharge your shock if you were at your house with your truck immobilized, much less in the middle of nowhere in the dirt?

And this is why Power Tank has taken their well-known CO tank technology and gone another step with this completely portable N Race Shock Inflator Kit. With Power Tank's nitrogen kit, you can check, change, refill, and recharge your own rebuildable shocks without having to stop by a shop that carries nitrogen shock filling equipment.

Power Tank's nitrogen tank is refillable and comes empty for shipping purposes, but you can get them filled at your local welding supply shop or any other place that carries nitrogen. Power Tank even supplies the refill kit that allows you to scavenge nitrogen off of any larger nitrogen tank.
