Mount Assembly Instructions

Shock Absorber Installation
• Depending on the specific model and options, rack will come with 2 or 4 Shock
Absorbers.
• Note: These shocks are very
stiff. To extend the shock for
mounting, it may be necessary
to bolt the upper end of the
shock to the rack and hang on
the bottom to get it to extend.
• Shocks have a number written in
white on them. The higher
numbers should be installed on
the east side of the Shock
Mounting Arm(s). This will
improve wake-up times.
• Use the Loctite® provided and
bolt shock to the Truss Tube and
Shock Mounting Arm as shown in diagram.
• Make sure to leave 1/8” space between bolt head and hex nut to allow for movement of
rubber grommet.
• On the UTRF-168 there are two possible locations for the upper shock bolt. The inside
set of square nuts is the default position. If high winds are an issue, the outside set of
square nuts can be used for more resistance against gusts.
• Tighten the hex jam nut (on top) and the pair of nuts (bottom) to 165 ft-lbs. A medium-
sized adjustable wrench or pliers is not sufficient for this amount of torque.
• This is high-stress connection and should be checked periodically.
Installation of the Counterweight
• The Counterweight assembly bolts to the
1” square nut welded on the north-end
Truss Tube, directly underneath the
bearing.
• Making sure the 1” all-thread rod is fully
engaged with the threads of the square
nut, turn the Unistrut® so that the open
face is pointing towards the mounting
pole.
• Tighten jam nut firmly.
• The 25-pound weight should be installed
at a point approximately 2/3 the way
down the Unistrut®. Fine adjustments
are best made after monitoring the
performance of the rack.
• See diagram for placement of hardware.
