STEP 12 - ADJUST PLATFORM (IF REQUIRED)
NOTE: Before doing the following proce-
dure, make sure vehicle is parked 
on level ground.
1. Lower platform to the ground. With the 
platform and fl ipover unfolded, raise plat-
form to bed level (FIG. 51-1). Measure 
how much the outboard edge of platform 
rises above bed level (FIG. 51-1). The 
outboard edge can be a maximum of 1” 
above bed level if bed height is 48” to 53”. 
If bed height is 54” to 55” the outboard 
edge is level (FIG. 51-1). If indication is 
correct, Liftgate is installed correctly and 
no adjustment is needed. If the outboard 
edge is below bed level, do instructions 2, 
3, and 6. If outboard edge is higher than 1”, 
do instructions 4 through 6.
3. Weld shims (parts bag item) on both 
platform stops (FIG. 51-3) to raise 
outboard edge of platform to correct 
position.

2. Compare measurement “A” (FIG. 
51-2) with the distances and shims 
in TABLE 51-1. For example: If 
measurement “A” (FIG. 51-2) is 
1” below level and you want to raise 
outboard edge of platform 1” above 
level, use 1/8” shim to raise 2”           
(TABLE 51-1).
