Operation

Bump Shock Adjustments

Never attempt to adjust the Bump Shock Assembly (A)

while under tension and always apply spray lubricant to

threads before adjusting for ease of operation.

Bump Shock Pressure

The Bump Shock Assembly (A) is pre-charged with the

proper amount of Nitrogen gas to suit most applications.

Therefore it should not be necessary to adjust bump shock

pressure prior to installation.
The Nitrogen charge is factory preset at 150 psi. For ap-

plications that require a higher or lower compression rate,

the gas pressure can be manually adjusted to a minimum

of 100 psi and a maximum of 200 psi.
To adjust pressure, the Bump Shock Assembly (A) must be

removed from the vehicle. Nitrogen pressure is adjusted

through the Schrader valve on top of the bump shock.

Care should be taken when discharging the bump shock to

ensure that no oil is lost. Most shops that service off-road

racing or motorcycle shock absorbers can adjust bump

shock pressure.

Maintenance

Regular cleaning with pressurized water is recommended

to maximize ease of operation and reliability.
In addition, the 3/8” drainage holes that you drilled imme-

diately above the Jounce Adapters (C) must be checked

periodically for blockages. If necessary, clear debris from

the holes to ensure any moisture trapped inside spring

retainer is able to self-evacuate.
