Lift Installation Instructions
Base Plate Mounting
There
must be a total of eight
3/8"-16 x 4" carriage bolts (
or
8"
bolts)
securing the base plate
through the floor
. Two 3/8"-16
x 8" bolts are supplied for bolting
through vehicle floor framing
members if applicable.
Optimum Bolt Locations:
The
mounting bolts
must
be inserted
in the mounting holes provided in
the base plate. Locate mounting
bolts as shown in Figure I
(straddling the towers). The
holes are positioned straddling
the towers in order to minimize
vertical upright deflection
(details on page 16).
Read warning on opposite
page.
Check under the vehicle
for possible obstructions such as
fuel tanks, heat shields, fuel lines,
wires, exhaust, framing members,
etc.
Carefully
drill eight 3/8"
diameter mounting holes through
the vehicle floor in alignment with
the base plate mounting holes.
Base Plate Wedges:
When base
plate wedges are used, the out-
board mounting bolts must be
inserted through the mounting holes
in the wedges (two per wedge).
See Figure H on page 12.

Four underfloor reinforcement
brackets are supplied.
Standard
Installations:
One reinforcement
bracket must be used to secure
the base plate below the floor at
both ends of the base plate (unless
inboard base plate mounting bolts
penetrate vehicle chassis
subframe members).
Ford Rear Door Installations:
All
four reinforcement brackets must
be used (details on page 15).
OEM van floors are becoming
lighter in an effort to improve
weight and fuel efficiency. 1/2"
marine grade plywood subfloor is
recommended for use between the
lift base plate and the van floor.
Extend the plywood as far as
possible beyond the base plate
footprint to reach key van floor
support points. The mounting
surface must be even and level.
Underfloor reinforcement brack-
ets can be positioned facing
inboard, left or right as shown in
Figure J. The spacing of the
reinforcement bracket mounting
holes matches the mounting hole
spacing of the lift base plate (two
standard size base plates).
Two
base plate mounting bolts must
secure each bracket
.
