GUIDELINES FOR MATCHING HITCH TRUCK AND TRAILER
WARNING:
Failure to check and follow tow ratings could result in tow vehicle
damage or truck and trailer separation while towing.
•Trailer and its contents together must not exceed truck, hitch and/or trailer tow
ratings.
•Towing vehicle must have a manufacturer’s rated towing capacity equal to or
greater than the gross trailer weight (dry weight of the trailer plus payload of the
trailer). (Figure 2)
•Gross weight of trailer must not exceed fifth wheel hitch rating.
•King pin weight must not exceed fifth wheel rating (Figure 3). If in doubt have king
pin weight measured by a qualified technician.

1. Maximum Gross Trailer Weight of : 18,000 lb / 8160kg.
Vehicle tow rating: _______________.
Total calculated Gross Trailer Weight (Figure 2):______________.
*Trailer weight should be the lowest of these recorded ratings for safe towing conditions.
2. Cequent Towing Products hitches are designed for use with recreational fifth wheel trailers only. Hitch applications other than
recreational fifth wheel trailers must be approved in writing by Cequent Towing Products’ Engineering Department.
3. Use only a SAE 2-inch kingpin with your Signature Series Fifth Wheel Hitch.
4. Approximately 15%-25% of trailer weight should be on hitch (Pin Weight)(Figure 3).
5. Trucks come in many different configurations. Cequent Towing Products’ hitches are designed for use in light trucks such as the
Ford F-Series, the Chevy Silverado and the Dodge Ram. Cequent Towing Products recommends the use of long bed (8ft) light
trucks for the best combination in truck - trailer turning clearance.
Rule of thumb:The distance from the back of the truck cab to the center of the rear truck
axle (“X” in Figure 4), should be approximately 4 inches greater than one-half
the trailer width (“Y” in Figure 4)

Figure 4
TRUCK
6. If a short bed pickup (less than 8 ft. but longer than 6 ft.) is to be used for towing, Cequent Towing Products recommends the
trailer be equipped with an extended pin box to help gain additional truck - trailer turning clearance (See trailer manufacturer for
options) (Figure 5). It also may be helpful to add a
speed, non-highway maneuvering.

WARNING:
Do Not install this fifth wheel hitch on or attempt to tow with a short bed pickup
truck that has a bed shorter than 6 ft.!
7. The height of the hitch and the pin box should be adjusted so the trailer is approximately level as it is towed. Allow
approximately 6 inches clearance between the top of the pickup walls and the underside of the front of the trailer for pitch and
roll of the trailer. (Figure 6). Allow more clearance between pickup walls and trailer for off road use.
Figure 6
Approximately 6 Inches
Level Trailer
CAUTION:
The measurements above are guidelines. If your measurements are close to these numbers re-check clearances. If
vehicle and/or trailer has any added bed vicinity accessories (i.e. fairings, air dams, ground effects, bed rails, etc.).
Additional dimensioning and clearance checks have to be made.
8. Hitch height determination:
With trailer leveled and on level ground measure from the ground to the king pin box (“A” in Figure 7). Secondly measure from
the height of the inside of the truck bed (“B” in Figure 7). Determine the amount of clearance over the side rails ( “C” and “D” in
Figure 7), as mentioned in Note 7.
Hitch Height = A – B + 2”
The 2” value is an estimate of suspension compression due to king pin weight of the trailer. This compression could range
between 1”-5” depending on the truck being used and the trailer being towed.
D – C + 2” > 6” as in Note 7.

9. If a lube plate is to be used with a Signature Series 5thWheel it must be at least 12” in diameter. Cequent Towing Products offers
this optional lube plate as part # 83001 / 40001.

WARNING:
•Connection for trailer wiring must be located at the side of the truck bed between the driver’s
seat and the rear wheel to prevent operators from working between the truck and trailer.
•Avoid putting any part of your body under the trailer or between the truck and trailer.
Unexpected or accidental movement of the truck or the trailer can cause serious injury or death
•If you must place any part of your body under the trailer or between the truck and trailer you
MUST
perform ALL of the following steps:
•Check that the truck transmission is in park
•Check that the emergency brake is on
•Block in front of and behind all trailer tires
•Check that the trailer landing gear are resting on firm ground

CAUTION!
Read pages 2-4 of these instructions before starting installation. Failure to do so could result in significant vehicle damage!
1. The following instructions should be used to mount the 5th wheel. Care and attention to detail will ensure a quick
quality installation. Check parts against parts list to become familiar with parts in kit. (Figure 1)
2. Raise rear of truck high enough to allow jack stands to be placed under rear spring hanger bracket of truck. This
will provide maximum room to install the 5th wheel brackets.
WARNING:
If the truck is raised, be sure that the truck is properly blocked and restrained to prevent the truck from falling.
Failure to do so may result in the truck suddenly falling, causing death or serious injury.
3. Remove plastic bed liner if applicable. Plastic drop-in bed liners will be cut later. Spray-in bed liners and bed
mats less than 1/4” thick will work with normal installation instructions. Note: Consult installer for recommended
curing time on spray-in liner before cutting holes through bed.
CAUTION:
Check for obstructions before drilling. Failure to do so could result in damaged fuel or brake lines, structural
members, etc. CEQUENT TOWING PRODUCTS does its best to communicate tow vehicle manufacturer
changes; however, it is ultimately the responsibility of the installer to prevent damage due to installation.
4. Use only CEQUENT TOWING PRODUCTS supplied bolts, nuts, and washers to install this kit. All bolts and nuts
are grade 8 unless specified otherwise.
5. These instructions are intended for a specific group of trucks. If these instructions do not apply to your vehicle,
contact Technical Service to get proper instructions. Each frame bracket must be bolted to the vehicle frame with
two bolts.
6. On older models a metal heat shield runs underneath truck bed. Remove and discard heat shield from
beneath truck bed if applicable. Heat shield adhered to bottom of bed on newer models does not need to
be removed.
CAUTION:
These instructions are guidelines only. Actual installation is the responsibility of the installer and the owner.
Always measure truck and trailer before installing hitch to be sure that there is clearance at the cab and at the
bumper to allow for turns.
7. Locate the area where the base rails will be inserted above the wheel on the drivers side. There are two hat
channels supporting the truck bed over the wheel. The base rails will be inserted at the location behind the forward
hat channel. The edge of the truck bed is flanged down. To create clearance for inserting the rails there are two
options. Either loosen truck bed bolts to lift truck bed, or the flanged area must be bent out using pliers or vice
grips. (Figure 8) To prevent scratching the paint on the flange cover the flange with a soft cloth before gripping
with pliers or vice grips.
8. Insert rails as shown in the following steps (Figures 9 through 11). Rails should be inserted flat side up.

Step 4 :One rail should be rearward and the other rail forward. The rails should be
centered with both ends of each rail resting evenly on the frame. After rails are
inserted and in place the flanged area of the bed liner can be straightened with
vice grips or pliers, be sure to use a soft cloth before gripping flange to
prevent scratching. If flanged area is scratched immediately follow
manufacturer’s recommended method of touching up scratched area to
prevent rust or other corrosion.
9. If there is a brake cable bracket located above the rear axle on the driver’s side of the frame, then disassemble and
remove the brake cable bracket (Figure 12). Do not discard the brake cable bracket it will be re-attached later.

WARNING:
DO NOT lubricate threads. It may cause bolt failure.
11. Loosely attach frame brackets to mounting kit rails using 5/8” X 1 1/2” long bolts, flat washer, and lock washers
(Figure 14). Tighten all mounting kit bolts to hand tight.
Check for obstructions before drilling. Failure to do so could result in damaged fuel or brake lines, structural
members, etc. CEQUENT TOWING PRODUCTS does its best to communicate tow vehicle manufacturer
changes; however, it is ultimately the responsibility of the installer to prevent damage due to installation.
12. Align hole in bracket with hole in chassis for 2007 and earlier models. After checking to ensure that rails are square with each
other, at forward mount hole location, drill pilot hole in frame using frame bracket as a template. For 2008 and newer models,
position complete assembly near or against truck bed hat channel towards rear of vehicle and drill a pilot hole in frame, both
sides. Enlarge pilot holes to 21/32” diameter holes (Figure 15). Optional: Spray undercoating around drilled holes to prevent
rusting.

13B. With 2005 and newer super duty models where suspension components block access to the front drilled hole on
the passenger side of the vehicle thread 5/8” x 1 1/2” knurl bolt onto pull wire (Figure 17). From the inside of the
chassis rails insert straight end of pull wire into drilled hole. Pull wire out through drilled hole and mounting hole in
bracket (Figure 16), unthread pull wire from knurl bolt. Thread washer, lock washer, and nut onto knurl bolt from
the outside of chassis rails and tighten until hand tight.
Note: Standard bolt and spacer will not be used in this case.
14. Using pointed bolt (Figure 19), screw pointed bolt in to the nut that is welded to the rail assembly until a prick mark
is clearly visible on the truck bed (Figure 18). If access to a welded nut is obstructed by chassis components, a
fourth prick mark should be made on the bed based upon measuring from the other prick marks (Figure 20). If a
plastic bed liner is used cut 19” X 4” slots in the liner measured from prick marks in truck bed. If the Signature Series
slider fifth wheel assembly is used, then see fifth wheel slider assembly instructions for slot cut dimensions.
15.Remove 5/8” x 1 1/2“ bolts attaching frame bracket to mounting rails. Remove front rail as per instructions in
step 7. Move rear rail rearward or forward to prevent interference with hole drilling or punching of truck bed.
CAUTION:
Check for obstructions before drilling. Failure to do so could result in damaged fuel or brake lines, structural
members, etc. CEQUENT TOWING PRODUCTS does its best to communicate tow vehicle manufacturer
changes; however, it is ultimately the responsibility of the installer to prevent damage due to installation.
16.Drill pilot holes in truck bed at prick mark locations. With hole saw saw 2 1/2” hole centered at pilot holes.
Note: Consult installer for recommended curing time on spray-in liner before cutting holes through bed.
Optional: Spray under coating around 2 1/2” holes to prevent rusting.
17.Loosely reattach rails to frame bracket.
18.From truck bed attach pucks and trim rings to rails as shown in Figure 21 using 5/8” button head screw and
lock washer. Tighten to 110ft.lbs. torque.
