A shock inflation tool is required for gas charging Penske and other racing dampers after service.
This rugged, portable tool from Longacre features a digital pressure gauge that reads to 350 psi in 0.1 psi increments for accurate filling. The special Schrader valve coupler is designed to separate hookup from valve actuation so your charge isn't lost when you install and remove the tool from the shock.
To use, screw the coupler onto your damper Schrader valve using the large-diameter knurled knob. Then turn the smaller black knob to open the Schrader valve. Shock pressure will now register on the gauge. Now use the Schrader valve at the end of the tool to pressurize the damper from your nitrogen bottle. In the event you get more pressure in the shock than desired, a bleeder valve below the pressure gauge lets you bleed off small amounts of pressure.
Fits Penske and other brands of racing shocks using a standard Schrader valve. Sold individually. Includes protective carry case.
