Hitch Assembly
Hitch Assembly for 20,500#:
If the hitch type to be installed is a 20,500# (Part #0800), there is no assembly required
except to attach the Base Rails to the base feet of the hitch Base using the four 1/2” Base
Rail Pins and four #3 Pin Clips (See exploded drawing on page 3).
This hitch has four height settings and should be adjusted according to the directions
found in the Operators Instructions found in the same box as the hitch. Be sure to torque
all four 1/2” x 1 1/2” Bolts to 75 foot pounds after adjusting height.
Hitch Assembly for 15,500#:
If the hitch type to be installed is a 15,500# (Part #1200), it will be necessary to assem-
ble the hitch first. Refer to page 3, the exploded view of this hitch and the parts list below
the drawing then follow these steps:
1. Attach the Base Sides to the Base Rail Assembly using the four 1/2” Base Rail Pins and
four #3 Pin Clips.
2. Remove the 3/4” x 7” Pivot Bolt from the Rocker Arm and Crossmember.
3. The Rocker Arm is shipped upside down in the Crossmember for better packaging and
will need to be removed and reinstalled right side up in the Crossmember as shown in
the exploded view drawing on page 3. Tighten the 3/4” x 7” Pivot Bolt only enough to
flatten the 3/4” Lock Washer or enough so that the Rocker Arm will rotate stiffly. Lu-
bricate the 3/4” Pivot Bolt with heavy grease before installing.
4. Fasten the Crossmember and Base Sides together using six each of the 1/2”-13 x 1
1/2” Bolts, 1/2” Lock Washers and 1/2”-13 Hex Nuts, tighten bolts to 75 foot pounds.
This hitch has four height settings and should be adjusted according to the directions
found in the Operators Instructions found in the same box as the hitch.
5. Fasten the Fifth Wheel Plate in the Rocker Arm using two each of the 1/2” Clevis Pins
and #3 Pin Clips after installing the Release Handle and Main Spring as shown below.
Be sure to install the Main Spring so that the end with the swivel hook is inserted into
the open end of the Release Handle as shown below.

General Installation Instructions
NOTE: Refer to the Specific Vehicle’s Figures
and Reference information for all references
made herein. The location of the Specific
Vehicle can be found by referring to the Table
of Contents.
Truck Preparation
1. Check part quantities using the Parts List for the
specific vehicle type.
2. Block vehicle wheels. Some vehicles may require
you to raise the rear of the truck in order to make
it easier to drill for installing the Mounting
Brackets on the truck frame.
3. You may wish to remove the wheels, to give
yourself greater working room.
4. At this point, the bed should be laid out and
marked for drilling using either the LAYOUT
METHOD or the TEMPLATE METHOD.
Marking Bed for Drilling (layout
method)
1. For layout using the Template method, see Layout
(Template Method) on next page.
2. See Truck Bed Layout Dimensions table pg. 7
for the dimension values for items A -D located
in the ‘LAYOUT METHOD’ illustration.
Measure and mark from the back of the bed
forward the values for Aand B. Do this at any
point on both sides of the bed.
3. Draw a line across the bed from mark to mark.
4. Find the centerline of the bed. Draw a line down
the middle of the bed from front to rear. See
Figure 5 on pg. 7. Center the measurement of C
across the centerline at the front most line you
made in step 2, and mark the measurement on
each side (parallel to the centerline). Center the
measurement of Dfor the rear most line made in
step 2, and again mark the measurement on each
side (parallel to the centerline). This will locate
the 4 drill holes.
5. Go to your truck’s SPECIFIC LISTING (listed
in the Index on pg.2) and perform the steps listed
in PART I. The truck Specific Listingsbegin
after page 7of these instructions.
Drilling the Bed
1. After you have removed the Mounting Brackets,
use a 1 3/4” hole saw, centered over the 1/16”
pilot hole, cut the bed for the mounting posts.
2. De-bur inside the holes, then use a paint stick to
touch up the edges.
3. Re-install the Mounting Brackets and secure those
that have no existing mounting holes in a
temporary fashion, using ‘C’ clamps. Those that
have holes, secure by lightly attaching with bolts
( tighten sufficiently to where the Mounting
Brackets lay flat against the truck frame).
4. Install the Mounting Posts through the bed into
the Mounting Bracket Post Holders. Rotate the
Posts a quarter turn. (See the illustrations in the
truck Specific Listings).
NOTE: The Mounting Post should be tall enough
to clear most bed mats. Vehicles using bed liners
may require taller Mounting Posts to seat into the
Post Holders properly. A Tall Mounting Post (1”
taller) is available under part # 330705. Four posts
are required for installation.
5. Remove the Base Rails from the shipping carton,
leaving the Base Rail Extensions loose to allow
lateral movement as you place the Rail assembly
over the Mounting Posts. See drawing on next
page.
6. Install the Base Rails in the bed of the truck, and
center the Base Rails between the Base Rail
Mounting Posts. Finger tighten the Base Rail
mounting Bolts.
7. Set the 5th Wheel Hitch on the Base Rails, and
align the Hitch Assembly with the Base Rail
mounting holes, using a drift pin punch to aid
your alignment. Install the Mounting Pins from
the inside. Then install the Pin Clips, to secure the
Hitch assembly to the Base Rails. See drawing on
next page.
8. Center the Hitch assembly within the truck bed,
from side to side. You might need to use a rubber
mallet to get the unit to move while centering.
Once the unit is centered, tighten the Base Rail
Extension Bolts to 31 ft. lbs..
9. The 5th Wheel Hitch, and the Base Rails, must be
removed to verify that the Mounting Post can be
inserted and removed freely, without binding. A
slight adjustment might be required to obtain un-

Layout (Template Method)
A Template set containing all available
Templates can be ordered, P/N 08400000,
from your distributor. Templates do not
come with the installation kit.
1. Lay the Template in the truck bed, centering it
from side to side, and parallel to the end of the
truck bed, using the dimension Xlisted in Truck
bed layout dimensiontable on pg. 7.
2. Mark the 4 holes, while making sure the template
does not move.

10. Reinstall the Mounting Posts, the Base Rails, and
the 5th Wheel Hitch assembly.
11. Complete the final steps needed to install the
Mounting Brackets to the truck frame. Go to the
truck Specific Listings, Part II at this time.
12. Due to slight inconsistency in manufacturing
processes, it is recommended that you mark the
Base Rails in such a manner that you will be able
to re-install them into the same relative position as
you have them presently installed.

FORD SD 1999 to Current Year
PART I Truck Preparation
1. Unfasten the emergency brake cable bolt (A) on the driver’s
side of the frame. (See drawing Ford 1). (B) is the overload
spring bracket, if equipped, and must be removed at this time.
Mounting Bracket Installation,
1. Place the driver side Mounting Bracket against the truck frame,
aligning the hole C, and the hole directly above hole C. (See
Ford 1, as your guide for placement of the Mounting
Bracket). Be sure to place the Mounting Bracket behind the
emergency cable.
2. Temporarily attach the Mounting Bracket to the frame,
using the 3/4” x 2 1/2” bolt in hole C, and the 3/8” x 2” bolt
into the hole directly above C (Figure 1 above). If the truck
is equipped with overload springs, use one of the bolts that
you removed when taking the overload bracket off, and
place the bolt into a hole B. If the truck is NOT equipped
with overload springs, use a 1/2” x 1 1/2” bolt provided (Figure 1 above).
(Some Mounting Brackets may have a slight warp to them due to the metal characteristics during
the welding process. If the bracket has a warp, you will need to draw the bracket tight against the
frame using either the bolts or by adding a clamp to assist in drawing the bracket against the
frame.) Tighten sufficiently to hold the Mounting bracket tight against the frame.
3. Install the Mounting Bracket on the passenger side repeating steps 1-3, except there will not be
the emergency brake cable to have to contend with.
4. Figure Ford 2 illustrates the drilling of the truck bed, using a 1/16” drill.
5. Drill the first 1/16” hole in the truck bed over the rear Post Hole on the driver side Mounting
bracket, where you made the mark during Truck Bed Layout. The bit should come down through
the Post Holder of the Mounting Bracket, centered front to rear and side to side.
6. If the first pilot hole is off center (front to rear) to the post holder, adjust the drill placement and
re-drill.
NOTE: If you have to re-drill in order to be centered, remember to adjust the other three holes
accordingly.
7. Drill the remaining three pilot holes, again checking to be sure the hole in the center of the Post

1. Attach the brake cable to the Mounting bracket using the 3/8” x 2” bolt through hole A(directly
above hole Con the driver side). (See Figure 1).
2. Install bolts B(Figure 1), or use the bolts that were removed with the overload spring bracket
into the Bindicated holes, and tighten. ( It may me necessary to drill these holes out to 1/2” to
accept the 1/2” bolts ).
3. Install the 3/4” bolt Cshown in figure 1.
4. Drill hole Dto 1/2”, and fasten on the driver side with the Bolt Plate shown in Figure 1, and on
the passenger side with 1/2” x 1 1/2” bolt D.

PART I Truck Preparation
1. For the 6’ bed truck, cut off the lower sheet metal support as shown illustrated in figure Dodge-1 on both
the driver side and passenger side of the truck bed, if this sheet metal exists.
Mounting Bracket Installation,
1. Locate the two existing holes that are to be used to mount the front Mounting Bracket, as shown
in the drawing of Dodge 1. Install the Mounting Bracket over the holes, using 5/8” x 1 1/2:
bolts. Tighten sufficiently to hold the Mounting bracket tight against the frame.
2. Install the Mounting Brackets on the passenger side repeating steps 1.
3. Drill the four pilot holes in the truck bed where you marked the bed during Truck Bed Layout.
Check each of the holes to be sure that the pilot hole is centered in the Mounting Post Hole.
Adjust the drill holes if needed. Keep in mind that realigning any one hole will affect the relative
spacing of the other pilot holes. The pilot hold should come down in the center of the Mounting
Post hole of the bracket.
4. Remove the four Mounting Brackets, and return to the General Instructions on pages 5 & 6
continue with ‘Drilling the Bed’.
PART II Mounting Bracket installation continued.
1. Install the Mounting brackets using the 5/8” x 1 1/2” bolts provided. The hardware is illustrated in the
Detail View of Mounting Plate Installation on page 12 .
2. Tighten all the previous installed mounting bolts on the Mounting Brackets. Torque all bolts per the table
on pg. 6.

PART I Truck
Preparation
1. Take note of drawing
Chevy-1. It should help
you position the
Mounting Brackets.
Mounting Bracket Installation,
1. From the truck bed, drill a 1/16” pilot hole over the forward most driver side hole that you
marked during layout. Then slide the Front Driver Side Mounting Bracket up in place, holding it
firmly against the truck frame. Check to see if the 1/16” hole aligns with the center of the
Mounting Bracket Post Hole.
2. If the drill bit missed the center of the hole in the Mounting Bracket, check your measurements
again. Re-drill the hole if necessary to get correct alignment. Adjust the other hole markings for
the remaining three holes if needed. Drill the pilot holes for the remaining three hole and check
each hole using it’s appropriate Mounting Bracket. Once the alignment looks good, remove the
brackets.
3. Go to “Drilling the Bed” on pages 5 & 6.
Part II. Mounting Bracket installation continued.
1. Drill the frame holes for the Mounting Brackets, using a 1/2” drill bit.
2. Install the 1/2 x 1 1/2” bolts to secure the Mounting Brackets to the frame.
The front Mounting Brackets require Nut Plates, so start both bolts into the Nut Plate before you
begin tightening the bolts. (Refer to the drawing above, and on page 18).
3. Tighten all bolts, torque all bolts per the table on page 6.

PART I Truck Preparation
After blocking the front wheels, place jack stands under the frame so that the rear of
the truck is high enough to allow the rear wheels to drop. This will give easy access to
the frame area in the rear wheel well. Remove the emergency brake cable bracket
located in the driver side wheel well, refer to figure 1 on this page. Replace this bracket
after installing the hitch mounting brackets. If the truck is a two wheel drive, remove
the axle jounce bumper located just above the axle on the bottom of the frame, replace
after the hitch is installed. If the truck is a two wheel drive one ton, this mounting
system will not work.
Refer to figure 1 this page, if the installation is for a six foot bed truck. Trim the cross
sill extensions located under the front bed cross sill even with the bottom of the main
cross sill as they will interfere with the installation of the Front Mounting Bracket.
Mounting Bracket Installation,
1. From the truck bed, drill a 1/16” pilot hole over the forward most Driver side hole that you
marked during layout on page 7. Slide the Rear Driver Side Mounting Bracket up in place,
holding it firmly against the truck frame. Check to see if the 1/16” hole aligns with the center of
the Mounting Bracket Post Hole.
2. If the drill bit missed the center of the hole in the Mounting Bracket, check your measurements
again. Re-drill the hole if necessary to get correct alignment. Adjust the other hole markings for
the remaining three holes if needed. Drill the pilot holes for the remaining three hole and check
each hole using it’s appropriate Mounting Bracket. Once the alignment looks good, remove the
brackets.
3. Go to “Drilling the Bed” on pages 5
& 6.
