Installation
WARNING! TO PREVENT SERIOUS INJURY: Do
not use this Leveling Stabilizer while unmounted.
WARNING! Before drilling holes, check for any
chassis components which may be inside the
frame. Look for electrical lines and wires, gas
tank, gas lines, water and holding tanks, generator
fuel lines and water heater lines. Make sure area
is clear of these components before drilling.
1. Park RV or Trailer on level ground. Prevent
the wheels from rolling by applying emergency
brake and wheel blocks (not included).
2. Check the following before
proceeding with the installation:
a. Attach Stabilizer to the frame of the
RV or Trailer using two c-clamps
(not included) or two vise grips (not
included). Close the Stabilizer using the
Handle Wrench (16) to check the frame
location. Make sure the Stabilizer will
clear any chassis components nearby.
b. Open the Stabilizer enough to touch
the ground. Recheck the location on
the frame and adjust if needed.
c. Once in place, apply enough pressure
between the ground and the Stabilizer to
ensure that it will not move during the rest of
the installation process. Remove the c-clamps
(not included) or vise grips (not included).
3. For Bolt-On Installation:
a. Hold the Stabilizer against the frame
and using the Mounting Brackets (9) as
a template, mark the locations of the
8 mounting holes on the RV or Trailer
frame. Remove the Stabilizer.
b. Use a center punch (not included)
and hammer (not included) to
mark the center of each hole.
c. Use a drill (not included) to make a pilot
hole 1/8". Then use a 5/16" drill bit (not
included) to complete each hole. Use
eight 3/8" tapping screws (not included)
with eight lock washers (not included)
to attach the Stabilizer to the frame.
4. For Weld-On Installation:
a. Hold the Stabilizer against the frame
and using the Mounting Brackets (9) as
a template, mark the locations of the 8
mounting holes on the RV or Trailer frame.
b. Weld at least four 1″ welds on the
Stabilizer Mounting Brackets (9)
when attaching to the frame.

Operating Instructions
Trailers, Travel Trailers and 5th Wheels
1. Park on level ground.
2. Level trailer (travel trailer, 5th wheel) front
and back with small carpenter’s level (not
included), or round bubble level (not included).
Place leveling blocks (not included) in front
of one tire on trailer. Slowly pull forward to
drive the trailer up onto the blocks. When
the trailer is level, stop and block all tires to
keep from rolling forward or backward.
3. Using Handle Wrench (16) lower the Stabilizer
on the lowest side first to get level. Use one
Stabilizer on each side for best results.
4. After Stabilizer makes firm contact with ground,
turn Handle Wrench (16) twice to insure
Stabilizer will not loosen from trailer during use.
Note: When RV or trailer will not be moved
for several days, periodically check Stabilizer
to be sure they have not worked loose.
Motor Homes
1. Park on level ground and level motor home
front and back (see step 2 in previous section).
2. Using Handle (16) lower Stabilizer on
opposite sides for stabilization (see
steps 3 and 4 in previous section).
Note: If motor home comes with factory
installed hydraulic levelers, the Leveling
Stabilizer can be used to provide additional
stabilization. Follow the directions for installation
found in this manual on pages 4 and 5.
