Step 1
Prepare the 5th wheel head unit for installation by locating
the hardware package containing four M14 hex bolts and flat
washers. The 16021 RAM OEM legs are compatible with the
following CURT 5th wheel heads: 16520, 16545, 16530, 16515.
Step 2
Select a set of mounting holes that will allow sufficient
clearance between the 5th wheel trailer and the sides of the
tow vehicle. Begin assembling the legs to the 5th wheel hitch
head using the M14 bolts and M14 washers (provided with
5th wheel head unit) through the selected mounting holes
and loosely secure them with the nylock nuts (#7) provided
in the 16021 hardware kit.
NOTE: Position the leg assembly with the operating
instruction label on the driver side of the tow vehicle.
The large locking feet on the 16021 will match the
large rear mounts in the truck bed.
Provide this manual, in its entirety, to the end-user. Read
and understand instructions before using this product.
Fully instruct and demonstrate the operation of this 5th
wheel hitch to the end user. Include the importance of
observing all warnings contained herein, including warning
labels on 5th wheel hitch mid section. Serious injury or
death may result if the warnings below are not observed.
To avoid serious injury, do not expose hands, body parts
or clothing between the truck and trailer or the truck's bed
sides and trailer. Extreme care should be observed to avoid
serious injury to self, property and observers.
Never exceed the rated towing capacity of the tow vehicle.
Trailer and contents combined must not exceed tow vehicle,
hitch and / or trailer tow ratings. Exceeding rated capacity
may result in separation and / or may result in damage to
5th wheel hitch, towing vehicle, trailer or cause death or
serious injury.
Never position yourself or others under the trailer's kingpin
area (danger zone) during coupling and uncoupling. Improperly
coupled trailers can separate and drop without notice.
WARNINGS
Step 3
With the legs in position, locate the cross support weldment
(#3). Loosely attach the cross support between the two leg
assemblies (#1, #2) with the provided M14 x 75 hex bolts (#4),
lock washers (#6) and flat washers (#5). See Figure 3.
Step 4
Remove the four lynch pins securing the locking handles
to the legs. Swing all four handles completely open and
lower the legs into position in the bed of the truck. Ensure
all four locking bolts and spacers drop into the mounting
holes before attempting to close the handles. See Figure 4.
Step 5
With the 16021 in position, torque all six M14 bolts
to 100 ft-lbs. Re-install the 5th wheel head if it was
removed to ease installation.
Step 6
With the legs secured and positioned in truck bed mounts,
rotate the handles back to the closed position. Secure the
handles by re-inserting all four lynch pins. Slight NOTE:
resistance should be felt as the handles are rotated closed.
If the handle will not close with moderate pressure, adjustments
must be made to the locking T-bolt; see 'T-bolt Adjustment'.
WARNING: Forcing the handle closed may damage the locking
bolt and handle, possibly resulting in trailer detachment.
Step 7
Confirm all four locking bolts are engaged in the truck bed
mounts and the castle nuts are secured with the cotter pins.
Finally, double check to ensure all four handles are securely
locked with the lynch pins. The 16021 is now installed and
ready for use.
