Warnings:
Penske Racing Shocks never recommends running lower than 50 psi in our shocks depending on piston
and shims being used. Lack of nitrogen pressure could result in “cavitation” which can result in loss of
immediate damping and rider feel.
We also do not recommend using pressure higher than 300 psi. This could result in stress fractures in
main mounting components which may lead to seal or other failures.
Always check with Penske Racing Shocks technicians on recommended pressures for your application
and use.
Troubleshooting:
Signs of Fluid:
If the area around the shaft bearing and shaft exhibits a small amount of moisture, this is normal. In
order to reduce friction in the system, seal squeezes are slightly relaxed which serves the purpose to
allow a small amount of fluid to be wicked onto the shaft when the shock operates. If you see excessive
amount of fluid that may “pool” on the top of the shaft bearing, you may have a seal problem. Contact
your Penske representative at once.
Loss of Gas Pressure:
If the shock for some reason loses its gas charge, a tell‐tale sign of reduced or no gas pressure is that the
shock (without a spring) when compressed, will not return to its fully extended position, or gradually
gets much slower when reaching full extension. If you have experienced a loss of gas pressure, contact
your Penske representative at once.
