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.

TANKS + CARGO, ETC.

1. Check Tow Ratings:
Vehicle Tow Rating:_______________________.
Signature Series Hitch Rating:__________________
Gross Tra iler 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 conf igurations. 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 widt h (“ Y” in Figure 4).

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 or a SIDEWINDER Pinbox Coupler to help ga in additional truck - trailer turning
clearance (See trailer manufacturer for extended pinbox options or your hitch installer for a SIDEWINDER Pinbox Co upler)
(Figure 5). It also may be helpful to add a
maneuvering. If the pickup bed is less than 6 ft., a SIDEWINDER Pinbox Co upler MUST BE INSTALLED ON THE TRAILER.

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. unless the trailer is equiped with a
SIDEWINDER Pinbox Coupler!
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.

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 he ight determinat ion:
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 page 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. Plastic drop-in bed liners must be cut out of the way. Remove plastic bed liner if applicable. 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.
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.
6. Trim rear heat shield as seen in Figure 8. Reinstall heat shield once mounting kit is in place.
8. Loosely attach frame brackets to rails using 5/8” X 1 1/2” long bolts, flat washer & lock washers (Figure 15).

using (3) 5/8” x 2” bolts and (1) 5/8” x 1 1/2” bolt with loc-tite patch on driver side front, spacers, lock washers, and
nuts hand tight (Figure 17).
•If access to drilled holed is not possible because of chassis components slide spacer onto bolt and thread bolt into
pull wire (Figure 18). Guide wire through chassis to drill hole, then pull wire through chassis to position bolt and
spacer. Loosely attach lock washer and nut from outside of frame rail.

10. Using pointed bolt (Figure 19), screw pointed bolt in to the nuts that are welded to the rail assembly to make four
prick marks. (Figure 17) If a plastic drop in bed liner is being used cut 19” X 4” slots in liner measured from prick
marks in truck bed. (Figure 20) If the Signature Series slider fifth wheel assembly is used, then see fifth wheel slider
assembly instructions for slot cut dimensions.
11.Remove 5/8” x 1 1/2“ bolts attaching frame bracket to mounting rails. Move rails rearward or forward to prevent
interference with hole drilling or punching of the 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.
12.Drill pilot holes in truck bed at prick mark locations. With hole saw or knockout punch create 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.
13.Loosely reattach rails to frame bracket.
14.From truck bed attach pucks and trim rings to rails (Figure 21) using 5/8” button head screw and lock washer.
