INSTALLATION STEPS:
NOTE: Due to vehicle variations these installation steps are to be used as a general guide for all installs,
additional adjustments and fabrication steps may be needed to complete each install properly.
Custom 5th wheel bracket application information is available at http://curtmfg.com/
1. Place the (2) mounting rails across the truck bed between the wheel wells. Position the 5th wheel legs
between the mounting rails so that the tabs in the base of each leg will fit into the slots in the ends of the
mounting rails. Secure the legs in place with the rail hitch pins and clips supplied with the 5th wheel hitch.
Securely attach the 5th wheel head to the legs.
2. On most applications the 5th wheel assembly should be positioned so that it is approximately centered over
the truck axle and between the wheel wells on the bed floor. Note
: To keep the trailer from damaging the
cab on tight turns there must be at least 52” between the hitch and the cab. On long bed pickups, the hitch
center line can be up to 3” forward of the axle. On short bed pickups this position is not possible. A 5th wheel
roller such as a #16560 is required so the hitch can be moved rearward before making a tight turn.
3. When hitch is correctly positioned in the bed and the mounting rails are parallel, mark (4) attachment points
on the truck bed using (1) of the (3) 5/8” rectangular slots at the end of each mounting rail that fit best with
the truck frame rails. Check below the bed before drilling holes to see that all wiring, brake lines or other
obstructions are moved out of the way and will not be contacted by the drill. Move the hitch assembly away
and drill (4) 5/8” diameter attachment holes down through the bed at the previously marked points.
4. Reposition the mounting rails in the bed so that the square 5/8” hole in the end of each rail is lined up over
the drilled holes. Place a 3/4” thick spacer (CM-16150-SP1) under the ends of each mounting rail, in line
with the drilled holes as shown.
5. Under the bed of the truck if the bed corrugation above the angle bracket is UP, leaving a space above the
angle bracket, place a spacer (CM-16150-SP2) in the bed, under the mounting rail as shown. Bolt parts
loosely in place as shown.
6. Position (1) of the mounting brackets under the bed and align with the 5/8” carriage bolts protruding down
through the bed. Use the driver and passenger side angle brackets at locations where frame obstructions
will not allow the straight “L” brackets to be positioned. If frame rail is clear of obstructions, the angle brackets
may be placed at any location.
7. Move the installed straight “L” or angle brackets so that they rest tightly against the side of the truck frame rail
and underneath the surface of truck bed. Install the 5/8” carriage bolts down through the mounting rails and
brackets.
Note
: There are 2 lengths of 5/8” carriage bolts. Use the shorter bolts on applications where vehicle frame
rail clearance may be close to attachment point. Bolts can be used in any attachment location. Securely
bolt brackets in place. Be sure they are tight against the side of the truck frame rail. Torque all 5/8” fasteners
to 150 lb-ft.
8. Before drilling any holes, check inside the frame rail to be sure that there are no wires, brake lines or other
obstructions in the frame which may be contacted by the drill. Each of the brackets must be attached to the
frame rail of the truck with (2) 1/2” wheel bolts. Drill (2) 17/32” holes through the frame rail using (2) of the
holes in each angle bracket as guides.
CAUTION: Holes MUST be drilled 17/32” diameter, so that the wheel bolts will seat properly.
If the holes are too small the bolt may break. If the hole is too large it will not grip properly.
