Unwrapped my 23rd year in a row Christmas present



Attach the pressure regulator to the filler tank



Close the valve on the shock filler tool



Attach the filler tool to the sidearm regulator outlet coupler



Starting by pressurizing the front reservoirs

Attach the no-air-loss chuck on the reservoir shrader valve



Sidearm bottle hands-free holster with the new insulated overalls (appreciated new add - temperatures have been dipping into the F*teens in the northeast)

Turn the chuck to depress the center valve core open



Open the shock filler valve
Slowly turn the regulator **** open while watching the gauge on the shock filler getting to the desired pressure



Slowly open the filler tool to begin pressurizing the reservoir, fine tune closing to get to the desired level
Close the filler tank valve and remove the chuck from the reservoir shrader valve



Repeat at the other three corners





And I can finally say my dampers are now fully installed



JRZ's recommended pressure range is 150psi (10bar) to 350psi (24bar)

I set my dampers to
Front 220 psi and
Rear 170 psi

Between the 250 at all four corners our of the box from JRZ and Bryan's F200 / R150 recommendation

The lifting force can be calculated with the following formula

F = P x (0,25 x π x d2)
F = lifting force in kg
P = pressure inside the reservoir in bar
d = diameter of the pistonrod in cm


Anyone else who has done this knows it is a mundane process

Now I know how to use this new tool, and have a new fine tuning component to dial in on the track




Checked that box, short term goals are
to get the front Super Now shortened sway bar brackets in,
Improved Racing sway bar end links in, and
reset the front KTS UCA length taking the preload heim deflection out


Happy New Year - wishing you All a happy, healthy, and successful 2026!
