4.1 Chassis and Body Preparation
4.1.1 Mount frame clearance
The ILFP mount frame clearance will vary based on chassis/trailer bed height, lift gate platform
size and lift arm length. (Refer to the specific installation drawing for mount frame requirement)
- Determine the correct mounting clearance according to your specific lift and chassis.
- With long overhangs it is even more important to maintain Max ground clearance.
o GROUND CLEARANCE = BOTTOM OF LIFTGATE FRAME TO GROUND
- Rear body ‘U’ bolts and chassis cross member rivets may have to be removed to
accommodate installation. Removed attachments must be replaced with alternatives
approved by chassis and body manufacturers.
IMPORTANT (Truck Installation):
Prior to completion of the lift gate installation, after the lift gate mount plates are welded to the
chassis, the body long rails must be connected to truck frame with welded flat bars or shear plates
to prevent the lift gate from moving the body forward on the chassis.
Bed height =top of bed to floor when air bags are
inflated and on flat ground (dim "Y")
Mount frame clearance = dimension from back
of truck to spring / tire or air ride suspension components
that would interfere with liftgate installation (dim "X")
