                 SwayPro FAQs

> Top

Do I have to keep extra pins or clips like I did for my old hitch? No. SwayPro has self-locking snap up brackets. There are no loose parts to track. There are no pins or clips on the entire weight distribution hitch.

How much maintenance is there?
People familiar with other weight distributing, sway control hitches will appreciate SwayPro's minimal maintenance. SwayPro has two easily-accessible grease fittings that require a shot of grease about every other long trip. Accidentally over-greasing may result in a clean up task, but it will not damage the SwayPro.

Do I need to grease the spring bars?
Grease is captured inside the spring bar head. Grease is never applied to spring bars. Use a high quality moly-based bearing grease. Do not use a silicon-based grease.
(Example: use ThermaPlex Hi-Load grease (ThermaPlex part no. 70414) or similar. "Moly" = molybdenum disulfide.)

Should I keep some plastic bags to put over the ends of the spring bars when I take them out to keep the grease off my vehicle when I store them?
No. The SwayPro spring bars just snap out with a ¼ turn, and are always clean, and grease-free. No grease is ever applied to the spring bars.

Do I have to add an after-market sway control to the SwayPro?
No, SwayPro has designed-in sway control functionality.

Do I have to disable the sway control to back up?
No. You back up normally.

Do I have to buy a complete new system when I trade up to a heaver trailer?
No. You may need two higher-rated spring bars, but everything else is the same for the four different tongue weight ratings.

What size do I need?
The SwayPro hitch is supplied with one of four standard pairs of spring bars. Spring bar selection is based on your trailer's tongue weight rating. Spring bars are rated for 550, 750, 1000, 1500 lbs tongue weight.
Note: details on part numbers are located in the SwayPro Modification Guide, ie, page 27 of the Sept 2006 Application Guide booklet.

If I have a tongue weight of 500lbs can I use the BXW1000 spring bars?
You need to stay within your tongue rating. You would need to order the BXW0550 spring bars. Overly stiff spring bars yield a rough ride and can overstress a trailer tongue.

How long will a SwayPro last?
With proper lubrication and use, we expect your hitch's life to exceed that of your trailer. SwayPro hitches are covered by a limited life-time warranty.

How are the tongue brackets attached?
Tongue brackets are clamped to the tongue with clamping bolts or permanently attached with bolts through drilled holes.

How do the Sway bars lock?

The sway bars have a slotted groove on one end that inserts into the hitch head. Insert, twist, and the spring bar locks into place.

How is the head adjusted?
The SwayPro is adjusted with a simple thumb screw. Head mounting bolts are loosened (not removed), the thumbscrew is adjusted, and mounting bolts are retightened. Nothing is disassembled or removed from the hitch in this process.

The SwayPro has 4 points of control?
Yes. The SwayPro controls swaying motion between itself and the trailer tongue with a pair of control links that capture the spring bar tensioning chains and limit their horizontal movement. In addition, the SwayPro has two friction adjusting bolts in the head.

What controls the sway?
The SwayPro's four points of control exert forces on the trailer tongue and on the tow vehicle that are engineered to nullify sway.

How do I know if I'm using the correct chain link when tensioning spring bars?
Choose the chain link that lifts the spring bar end and aligns the spring bar in a position parallel to the trailer tongue frame.

Is there something I could do if I have to turn extremely short turning situation?
You just take normal precautions when making sharp turning maneuvers to make sure your tow vehicle and trailer do not contact each other.

Can I use SwayPro if I have surge brakes installed on my towed vehicle?
SwayPro’s dual benefits of weight distribution and sway control also work for you when your towed vehicle is equipped with surge brakes. SwayPro’s operation is unchanged when towing with a surge brake actuator in place of a simple hitch coupler. However, the effects of the small compression and return motion (approximately an inch) that occurs in the surge brake actuator effects conventional sway control, and surge brake manufacturers have established varying requirements for using their products with conventional sway control products and weight distributing hitches.

Whatever the limitations placed on other hitch products, SwayPro’s functioning is unchanged when towing with surge brakes. Blue Ox recommends that you check with the manufacturer of your particular surge brake actuator before using their product with any weight distributing hitch.

                   SwayPro Troubleshooting

> Top

Issue: After coupling the trailer to the hitch head, the pickup squats and the front of the trailer dips.
Resolution: Turn the thumbscrew on the hitch head out one full turn. If the pickup has excessive squat and the trailer dips in front, make multiple turns of the thumbscrew. If necessary, raise the chains of the weight distributing bars up by one link.


Issue: After coupling the trailer to the hitch head, the pickup is level but the front of the trailer dips.

Resolution: Move the hitch ball up one notch. More pressure on the spring boards puts more pressure on the front. If the front of the trailer needs only minimal adjustment, raise the chains of the weight distributing bars up by one link. Otherwise, adjust the hitch mount receiver higher. Each adjustment up or down equals 1 ½”. Once the truck and trailer are level then everything is correct. To adjust the tow vehicle to a level position, increase the spring bar tension by dropping one link on the chain on each side of the hitch at a time until tow vehicle is level.

Issue: There is excessive sway.
Resolution: Excessive sway may indicate that the trailer is improperly loaded. As a guideline, the tongue weight should be 10-15 percent of gross trailer weight. If it is not, redistribute the weight accordingly. If you encounter continuous sway or swaying that does not dissipate quickly, adjust the load and the SwayPro. You may have to repeat adjusting the load and the SwayPro. You may have to repeat adjusting the load and the SwayPro until sway stops. To adjust the SwayPro, tighten the two hex bolts on the underside of the head assembly using a torque wrench. Tighten the hex bolts in 10 ft.lb. increments to a maximum of 100 ft.lbs. The bolts are torqued to 40 ft.lbs. at the factory.

Issue: The ride is excessively rough.
Resolution: Insure the weight distributing bars are level. And you have the correct spring bars. Springs that are too heavy (1000 lb bars with a 700 lb tongue weight) will cause the trailer to ride rough.

Issue: The head unit isn’t clearing the bottom of the tongue during tight turns and backing up.
Resolution: If the tongue of the trailer is 5” or wider, a hitch ball with a rise may be required. Also: If one leg comes loose and the other is tight, take bolt completely out and add a lock washer and then tighten to 55-60 lbs. Do this to both sides.
