GUIDELINES FOR MATCHING TOW VEHICLE 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). (See Fig. 2)

•Gross weight of trailer must not exceed 21,000 pounds for this product.

•King pin weight must not exceed 4,200 pounds (See Fig. 3). If in doubt have king pin weight

measured by qualified facility.

1. Check Tow Ratings:

Vehicle Tow Rating: ________________.

5thAirborne Pin Box Rating:________________.

Gross Trailer Weight (Figure 2):________________.

*Trailer weight should be the lowest of these recorded ratings for safe towing conditions.

2. The 5thAirborne pin box is designed for a maximum of 20% Gross Trailer Weight on the pin (Pin Weight). See Fig. 3

TRAILER WEIGHT

(PIN WEIGHT)

3. The Height of the hitch and pin box should be adjusted so the trailer is approximately level as it is towed. Allow

approximately 6 in. clearance between the top of the bed and the underside of the front of the trailer for pitch and yaw

of the trailer (See Figure 6). For off-road use allow more clearance between pickup walls and trailer.

Installation Instructions

5thAIRBORNE

ASSEMBLY INSTRUCTIONS

1. Before removing the original pin box, take note of the number of bolts used attaching the existing pin box to the

mounting wing set. Cequent Performance Products recommends using at least the same number of bolts upon

installation as removed from the original pin box. (Figure 5)

Mounting Wing Set

Figure 5

2. Remove the existing pin box, taking care to remove any necessary wiring and/or break away switch if attached to the

pin box. (If removed, the break away switch must be reinstalled after installation is complete)

3. Install the 5thAirborne inside the mounting wings (Figure 6), with exception to tube style pin boxes. Cequent Performance

Products recommends replacing the mounting bolts, nuts, and lock washers with the same size & grade as the bolts

removed from the original pin box. Torque all bolts to the proper value listed in table 1.

Note: Installing the front bolts first may ease alignment.

WARNING: The 5thAirborne pin box is heavy, take care to maintain
adequate support under the 5thAirborne arm until at least 2 bolts per side are
installed. Failure to do so may result in death or serious injury.

ADJUSTING THE AIR SPRING

1. Perform the hitching procedure following the proper hitching procedure according to the manual for your fifth wheel

Hitch.

2. Add air to the air spring at the valve shown in figure 7. Continue adding air until the skid plate is level (on level ground) see

figure 8. (Most units have the fill level label on the side of the lower jaw of the pin box, some will have the fill level label on

the shock.)

The fill level line is a good reference for setting air pressure in the spring, if more performance is desired the air bag
position and pressure can be adjusted to suite your preference. The air spring position can be adjusted by removing
the mounting bolts shown in figure 7 and moving the bag as indicated per your loading condition. A good starting
point for pressure setting is 80-100 psi. (Do Not Exceed 120 psi). If the ride is too soft, add more pressure. If the
ride is harsh, remove pressure. If the pressure adjustment cannot maintain a satisfactory ride, reposition the air
spring according to figure 7.

BEFORE EACH TRIP:

1. CHECK YOUR EQUIPMENT: Check that condition of all of your towing equipment and keep it in top condition.

2. Check to see that all bolts are properly tightened.

4. Check that the airbag pressure is set for your coach. (The skid plate should be near level when parked on level ground)

MAINTENANCE:

1. For ease of hookup; frequently lubricate the skid plate surface and the back side of the king pin.

2. Keep pin-box hitch painted to prevent rust and maintain a good appearance. (Do Not paint over labels)
