Secure Lift 
Attach Mounting Brackets to 
Vehicle Frame
Mounting bolts must be routed 
horizontally through the verti-
cal face of the “L” brackets and 
framing members as shown in 
Figures D, E and F.
Eight 3/8-16 x 1-1/2" hex bolts 
are supplied for bolting the all-
thread mounting brackets to the 
frame (two per bracket).  Oval 
slotted mounting holes are pro-
vided in the mounting brackets 
to allow adjustment. Carefully
drill 25/64" (.390") diameter 
mounting holes at the center of 
the oval mounting slots.
Channel Frame Applications:
Secure mounting bolts as speci-
fied in Figure D.  
Box Frame Spacers:  Position 
tubing spacers as shown at 
right to prevent collapsing the 
box frame. Carefully drill a 
25/64" (.390") diameter mount-
ing hole through one side of the 
box frame.  Drill a 5/8" (.625") 
diameter hole through the 
opposite side of box frame to 
allow installation of spacer.  Cut 
spacer tubing to length (equal 
to thickness of box frame).
Note:  A longer 3/8-16 bolt will 
be required for box frame appli-
cations.  Secure mounting bolts 
as specified in Figures E and F.
All fasteners must meet FM-
VSS 571.403 Section 6.3.

clamps along the sides of the lift hous-
ing until aligned with mounting bracket 
all-thread studs.  See Figure G.
Height Adjustment

aligned with vehicle chas-
sis
. Adjust the 3/4" hex jam 
nuts on the all-thread mount-
ing studs at all 4 corners of 
the lift until dimensions A, B, C 
and D are equal (within 1/16").
See Figure J.
In-Out Positioning
Position the lift to achieve a 2”
