2. Install 2 lock nuts per U-bolt, tighten u-bolt nuts. Make sure at least 2 threads are showing past the ends of the nuts.

4. Position the adjustment nut and locking nut to the outermost positions as shown in figure 5. If the

adjustment is difficult, as the adjustment nut must be turned by hand, apply a small amount of light penetrating oil such as

WD40 or PB Blast to the threads of the cam arm. Work the adjustment nut back or forward to get the penetrating oil into the

threads until the adjustment nut moves freely to the desired position.

3. Using a grease pencil or suitable marking device such as a marker and a straight edge locate and mark the center of the hitch

ball on the coupler both horizontally and vertically as shown in figure 4 . This reference point will be used to locate the cam

arm assembly position. Mark both sides of the coupler.

PRE-INSTALLATION (TOW VEHICLE MAY NOT BE PRESENT)

1. If the tow vehicle is not available at the time of installation of the Dual Cam HP system, position the yolk centered on the

threads of the cam arm (Approximately 2” from either end of the threaded portion of the cam arm. Run the adjustment nut

down to meet the yolk. Tighten the locking nut until the lock washer is fully compressed and continue to the Frame Plate

Installation portion of this manual for your specific frame style; Tubular Frame or C-Channel Frame.

2. Pass this manual along to the customer/end user of this product and inform them that minor adjustments to their cam arm

length may be required depending on head tilt of the WD system, number of chains used for proper weight distribution, tow

vehicle variance and/or; changes in tongue weight of their trailer as all of these variables will slightly affect the proper position

of the cam with respect to proper seating in the detent of the cam arm.

3. Direct the customer to the INSTALLATION WITH TOW VEHICLE PRESENT portion of this manual for hook-up procedure,

and fully explain proper seating of the cam within the spring bar detent. Refer them to their specific Weight Distributing Hitch

Instruction manual and be sure they follow the INITIAL HOOKUP section of their Weight Distribution Kit Manual for first

time hook-up and/or any changes in the variables listed in item 2. of this section occur.

4. BE SURE to pass along the Towing Information Packet (P/N: 110400) to the customer/end user and BE SURE they

understand the material within the Towing Information Packet for safe towing.

INSTALLATION WITH TOW VEHICLE PRESENT

NOTE: Set-up and adjust weight distribution hitch per the installation instructions for your Weight Distribution Hitch.

1. Connect the trailer to the tow vehicle. Tow vehicle and trailer should be on level ground and in a straight line. Raise the

tongue and rear of the vehicle enough to install the spring bars onto the dual cam arm with the trailer tongue jack

(approximately 6”-12” or until the spring bar can be lifted with the supplied lifting handle with very little effort, this will vary

depending on spring bar rating and head tilt adjustment).

WARNING:

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 set

Block in front of and behind all trailer tires

Check that the trailer jack foot is resting on firm ground

2. Install the spring bars into the ball mount head. Position the spring bar over the cam portion of the cam arm.

3. Install the Hanger Bracket (with the ends of the u-bolts facing inward) and Chain onto the cam by slipping the keyed slot of the

hanger bracket over the button end of the cam arm (figure 9). Rotate Hanger bracket to the vertical position and pull chain

vertical to the chain attachment point on the snap-up bracket (Figure 10).

Figure 9

Figure 10

4. Raise the chains until they meet the hook of the snap-up bracket, using the chain link furthest down the chain that allows you to

close the snap-up bracket by hand (without the supplied lifting tube – this is generally the 2

nd

or 3

rd

link from the free end of the

chain for most installation). Use the same link # for both sides of the trailer. Lift both spring bars with the snap-up brackets

and install the keeper pin in the snap-up bracket. Be sure that the hanger bracket is fully engaged in the slot of the cam arm.

5. Lower the trailer tongue jack.

6. Check that the cam is properly seated properly in the detent of the spring bar (figure 14). If the cam arm assembly dose not

automatically seat in the detent of the spring bar, rap the end of the cam arm with a

mallet or hammer until it seats into the spring bar detent as shown in figure 14.

7. Once the cam arms are properly positioned in the detent of the spring bar. Check the ride height of the tow vehicle per your

Weight Distributing Hitch Kit; specifically the Initial Hookup section of that manual. It may be necessary to adjust the number

of links engaged or the ball mount tilt for proper weight distribution for your tow vehicle and trailer. Re-seating of the

Cam Arm Assemblies in the spring bar detent may be necessary until the Initial Hookup requirements are met.

Run the adjustment nut shown in figure 5 down to meet the yolk. Tighten the locking nut shown in figure 5 until the locking

washer is fully compressed. This process needs to be done for both cam assemblies, i.e. both sides of the trailer frame.

8. The Cam Arm Assemblies are now ready to be permanently mounted to the trailer frame. Follow the proper instruction for

frame plate installation of this manual for your particular frame type.

TUBULAR FRAME DUAL CAM HP FRAME PLATE INSTALLATION

Before drilling, make sure there are no obstructions in the trailer frame where the intended bolt holes are to be drilled, such as

trailer wiring and or electric brake beak-away switch.

DO NOT drill through the opposite wall of the frame tube.

CAUTION:

WARNING:

When lifting/lowering Snap-Up Bracket, Avoid putting any part of your body in the path of the lifting handle

and under the cam arm and spring bars. Components of this system are loaded with substantial force and

could shift position or drop suddenly causing serious injury or death.

Never Raise or Lower Snap-Up Brackets without raising the trailer tongue jack to remove the load from the

spring bars and cam arms. Failure to do so could cause serious injury.

BEFORE EACH TRIP:

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

2. Check that the torque of all fasteners are in accordance to this manual.

3. Re-Check spring bar detent and cam alignment, and periodically while towing for the best performance.

4. Check for any excessive wear to any of the components of this system.

MAINTENANCE:

1. DO NOT – use grease on the cams or cam arms.

2. If noise of the system is offensive, a very light coating of lubricant such as Vaseline may be used on the portion of the

cam where the spring bar rides on the cam.

Tongue weights in excess of 1,200 lbs. may require the use of such a lubricant to prevent excessive wear.

3. Keep all painted parts painted to prevent rust and maintain a good appearance. (Do Not paint over labels)

CAM ARM ADJUSTMENT

1. Be sure that the truck and trailer are adjusted properly per the instructions for your Weight Distribution Hitch, pull forward far

enough to be sure the truck and trailer are in a straight line. (Picking a point at a distance away from the vehicle (about 100

yards) drive forward toward that point keeping the steering perfectly straight until the truck and trailer are perfectly in a straight

line.)

2. Go to each cam arm and check to see that the cam is perfectly centered in the detent of the spring bar. Make adjustments to

the cam arm length as required, it is important to have the cam arm/spring bar detent exactly as shown in figure 14.

3. Before adjustments to the cam arm length can be made, raise the trailer tongue jack and lower the snap-up brackets. Loosen the

Locking nut (figure 5) and move the adjustment nut (figure 5) until the cam is centered into the detent of the spring bar (figure

14). After making adjustments, lift both snap-up brackets and install retainer clips; lower the trailer tongue jack. Repeat step 2

of this section

3. Adjust the position of the snap-up brackets as needed, the chain should be perfectly vertical while in use to avoid damage to the

snap up bracket itself.

* From time to time, with changing towing/loading conditions, it may be necessary to use a different chain link to properly level

the tow vehicle (See your Weight Distribution Kit Installation Instructions). Anytime a different link is used, the cam arm

must be readjusted.

•Installation of an additional bolt into the snap up bracket when using

a Jayco RV with a coupler mounted to the bottom of the frame.

•If a hole does not already exist, mark the location of the hole to be

drilled into the snap up bracket. Center the hole from left to right and

place it 2-1/4” above the arc in the bracket. See the picture at left.

•Before the bracket is placed on the frame, drill a 9/16” hole in the

bracket

•Place the bracket in the correct place on the frame as directed in the

product instructions or replace it where it was if it had already been

installed.

•Using the hole in the bracket as a guide, drill a ¼” pilot hole. Be sure

to stay centered in the bracket hole.

• One method to stay centered is to use the 9/16” drill first. Just put a

small dimple into the frame with the 9/16” bit. Then finish drilling

with the ¼” drill bit and then a 7/16” drill bit to get the final hole. See

pilot hole to the left.

•Install the ½” self tapping screw into the hole in the bracket and

frame. Tighten it to 50 ft/lbs.

•Re-tighten the ½” set screw on the inside of the frame. Turn only

¼ to ½ of a turn after making contact with the frame.
