One of the most annoying steps in shock tuning is simply getting your Nitrogen Shock Inflator on and off the Schrader valve stem. Traditional shock tools use zero loss air chucks borrowed from the aviation industry which require a wrench to use, making it difficult or impossible to access the schrader valves on your shocks while they're on your rig. The T-Handle on top is also difficult to use and can cause sore fingertips after your fourth nitrogen charge.

Enter the PT Shock Chuck™! The Power Tank Shock Chuck™ is a no-air-loss chuck (aka NAL Chuck) that uses knurled thumb nuts on the top and bottom and the copper washer has been replaced with a synthetic material, lowering the torque specs needed to get an airtight seal on the schrader valve. We left wrench flats on the bottom nut in case extra torque is desired. 

The two knurled thumb nuts attach to the valve stem and depress the valve core pin in two separate actions. This allows you to close the shock under pressure, ensuring no N2 loss when you remove the Shock Chuck™. 

The PT Shock Chuck™ is rebuildable for years of use. 

This is the chuck that we use on our Shock Boss Shock Inflators (SIG-5600 and SIG-0500), the same shock inflators used by Fox Racing Shocks to tune Ultra4 Cars and Trophy Trucks for the King of the Hammers and Baja 1000 Off-Road Races. 

If you have a hard to reach or recessed Schrader valve, add a Schrader Valve Extension.

For IFP (internal floating piston) shocks that fill with a needle, you will need a Shock Fill Needle Assembly (SIG-5000). They work well with all of our shock inflators.

To convert this to male 1/4 NPT or FPT threads, choose the female thread and add:

Note: Do not twist the body while attaching or removing from valve stem or else you may damage the seal.

Details:

  • Stainless Steel
  • 1/8" FPT Female Thread
  • Used for Nitrogen Shocks and ORI Struts
  • Rated for 1000 psi
  • Rebuildable
  • Does not need wrench

No other shock inflation kit is as complete or as portable as the Shock Boss V2 in either single or dual fill versions.

Frequently Asked Questions

Nitrogen, N2, is commonly available at welding gas and air gas businesses across the country. You will rent a mother bottle (40 cubic ft is common) and use the included N2 Power Filler to transfill from the rented mother bottle to your Shock Boss tank.

No, BUT you can fill your shocks with CO2, safely. For that, you will simply need the Shock Inflator Gauge (SIG-5800, SIG-6000) plugged in to your Power Tank regulator and hose.

Both CO2 and N2 are dry, inert gases that have similar thermal expansion properties, outlined in the Ideal Gas Law.

We had to use CO2 to fill our Racer's shock at a pit stop and he ended up taking first place in that leg of the race!

All gas bottles in the USA must be recertified within 5 years of the date of last inspection. This is verified and enforced by the refiller (you) at the time of refilling.
