SwayProTM Owner’s Manual & Installation Instructions

Welcome to the Blue Ox® Family

The SwayProTM is a revolutionary hitch that not only handles weight distribution but sways prevention as well by using the combination of loaded spring bars, easy-to-use rotating latches and an integrated hitch head. As the trailer tries to sway it puts a heavier load on one side of the bars, as this happens the spring bars will pivot on the hitch head and balance each other preventing the trailer from swaying. The SwayProTM will also conquer weight distribution at the same time, putting more weight on the towing vehicle’s front tires which increase steering control and braking giving you a safer and easier driving experience. Your SwayProTM is backed by a limited lifetime limited warranty. Any unauthorized modifications to your SwayProTM may void the warranty.

Please read all of the technical documents, warnings, tips, and notes in this manual before operating your SwayProTM for the first time. Improper installation, use and/or maintenance may result in malfunction causing personal injury or property damage. Please fill out and return your warranty card. For future reference, your serial number is located on the outside of the manual packaging and is also located on the top of the hitch head of your SwayProTM.

Features & Benefits

• Open Head
  The open head design provides easy access for tightening the hitch ball.

• Powder Coat Finish
  The powder coat finish provides a professional appearance, aids in rust prevention, and prolongs the life of the product.

• Rotating Latches
  Rotating latches clear obstacles that are mounted above the frame.

• Greaseless Bars
  Grease is captured inside the bar pivots. No messy bars to deal with.

Frequently Asked Questions

What size ball shanks can be used?
Answer: The SwayProTM accepts 1″ or 1-1/4″ ball shanks.
Does sway prevention require adjustment?
Answer: No, sway prevention is built into the SwayProTM system and no adjustments are required.
What is gross trailer weight?
Answer: Weight of trailer (dry) + liquids (water, propane, sewage) + cargo. Measure gross trailer weight with a fully loaded trailer on a level surface, preferably on a public truck scale.
What is tongue weight?
Answer: Downward force exerted on the hitch ball by the trailer ball coupler. Measure tongue weight with a fully loaded trailer on a level surface with a trailer ball coupler at two heights.
Why do the bars bend?
Will they stay bent? Answer: The spring bars are designed to deflect 2″-3″ on a properly set system. This creates the necessary load on the spring bars to achieve an enjoyable ride. No, the spring bars will always return back to straight.
What size bars do I have?
Answer: The bars are marked with a dot system on the shank end to identify the weight rating.

• 350lb Bar = No Dots
• 550lb Bar = (1) Dot
• 750lb Bar = (2) Dots
• 1000lb Bar = (3) Dots
• 1500lb Bar = (4) Dots (shown)
• 2000lb Bar = (5) Dots

Important:
Use only genuine factory replacement parts on your SwayProTM. Do NOT substitute homemade or non-typical parts. If a bolt is lost or in need of replacement, for your safety and the preservation of your SwayProTM, be sure to use a replacement bolt of the same grade (In most cases it will be Grade 5, please reference the parts list above). Replacement parts may be ordered through your nearest Blue Ox® Dealer or Distributor. Failing to follow and/or altering these installation instructions in either installation or required equipment will void the manufacturer’s warranty.
SwayPro™ Owner’s Manual & Installation Instructions

Installation

1. Park the towing vehicle and trailer in a straight line on firm, level ground. Air-ride shock absorbers, air springs, or automatic leveling systems on towing vehicles should be disabled or deflated to the manufacturer’s minimum recommended pressure prior to SwayProTM installation. Unhook the trailer from the towed vehicle and level. Remove the existing receiver hitch.

2. Insert the hitch mount receiver shank into the towing vehicle receiver and secure it with the 5/8″ x 3″ pin and clip.

3. A 2-5/16″ x 20K ball is pre-installed on the hitch head. If needed use the 1.031″ ID spacer tube for 1″ ball shank. The hitch ball capacity must meet or exceed the gross trailer weight rating.

4. Level the trailer and then measure the coupler height. Install the hitch head onto the receiver shank, using the 3/4″-10 bolts, 3/4″ lock washers and 3/4″-10 hex nuts. Measure the hitch head ball height. The ball height needs to be the same or 1″ higher than the trailer coupler height, adjust as necessary. Torque the 3/4″-10 bolts to 257 ft/lbs.
   Note: Ram Truck owners please reference the Trailer Towing section of your vehicle owner’s manual for proper hitch set-up instructions. Also, it is recommended for optimal towing performance to set the ball height 2″ higher than the top trailer coupler.

5. Couple the trailer to the hitch head by placing the trailer coupler onto the hitch ball per the manufacturer’s instructions.

6. Measure 29″ back from the center of the ball coupler and mark this point on the trailer tongue framework on both sides. Center and mount the rotating latches to the trailer frame over the marked areas. Remove or relocate any obstructions on the trailer tongue framework if necessary. Finger tighten the bolts on the rotating latch at this time.

7.  Insert the spring bars into the bar pivots, insert pin and snap clip into place to lock bars in place.

8. After verifying that the rotating latches are in the proper position, torque the 1/2″-13 square head set screws against the trailer tongue framework to 40 ft/lbs and tighten the jam nut. (Do NOT use Loctite® Red on set screw.)
   IMPORTANT: The spring bar chain must be straight up and down in the center of the rotating latch when the towing vehicle and trailer are aligned. Reposition the rotating latch along the trailer frame if necessary.

9. Release the rotating latch by rotating or pulling out on the lock pin handle. Rotate the bracket using the wrench that was provided and turn clockwise until the chain slot is on the bottom. Insert the 9th chain link from the top (opposite the u-bolt) into the slot of the latch. Using the wrench, rotate the latch counterclockwise until the lock pin engages in the lock pinhole.
   Note: Adjustments to the number of links used may be necessary due to certain driving conditions and/or changes to the trailer after initial setup. Advancement to the 10th or 11th link from the top is recommended to compensate for these changes.
   Caution must be used when unlatching due to the potential of injury if the tension of the spring bar is suddenly released the wrench will rotate quickly. Hold the wrench firmly as the rotating latch bracket will rotate downward causing a quick jerk on the wrench. Rotate slowly and firmly.

10. Determine if the towing vehicle is level. If necessary, adjust the chain links.
    A. Support the weight of the trailer tongue with the trailer jack.
    B. Unlock the rotating latch bracket and release the spring bar tension on the chains.
    C. Adjust the chain to tighten or loosen one (1) link at a time.
    D. Reapply the spring bar tension on the chains by using the wrench to rotate the rotating latches in a clockwise direction until the lock pin engages in the lock pinhole.
    E. Lower the front of the trailer allowing the tongue weight of the trailer to be supported by the towing vehicle. Repeat the above steps until the towing vehicle is level.

11. If the trailer is not level, determine how much and in which direction. Each hole raises or lowers the front of the trailer 1-1/2″. Level the trailer by
    A. Support the weight of the trailer tongue with the trailer jack.
    B. Unlock the rotating latch bracket and release the spring bar tension on the chains.
    C. Uncouple the trailer.
    D. Remove the 3/4″ fasteners from the hitch head
    E. Move the hitch head on the receiver hitch mount either up to raise the front of the trailer or down to lower the trailer.
    F. Replace the 3/4″ fasteners in the appropriate holes and torque to 257 ft/lbs.
    G. Couple the trailer to the hitch. H. Support the weight of the trailer tongue with the trailer jack.
    I. Reapply the spring bar tension on the chains by using the wrench to rotate the rotating latches in a clockwise direction until the lock pin engages in the lock pinhole.
    J. Lower the front of the trailer allowing the tongue weight of the trailer to be supported by the towing vehicle. Repeat the above steps until the trailer is level.

12. Verify that the trailer and the towing vehicle are levels. If not, see the Troubleshooting section.

** WARNING**
We recommend that this product be installed by an authorized Blue Ox® Professional Installer. Improper installation and/or operation can create a hazard that can cause serious injury, property damage, or death. Improper installation and/or operation will void the warranty.

Operation

Hooking Up

1. Park the towing vehicle and trailer in a straight line on firm, level ground.

2. Install the hitch head/receiver mount assembly into the towing vehicle receiver tube and secure it with the 5/8″ x 3″ pin and clip.

3. Couple the trailer to the hitch head.

4. Install both spring bars into the bar pivot tubes.

5. Confirm that both of the rotating latches are tight on the tongue.
   Note: Before each tow, confirm that all bolts are tightened to specified torque specs.

6. Support the trailer tongue weight with the trailer jack to ease the tension on the spring bar chains and allow for easier latching. Attach the spring bar chains to the rotating latches with the appropriate chain link. Apply tension to the spring bar by using the wrench to rotate the latch counter-clockwise until the locking pin on the latch engages. Do this on both sides of the trailer.
   NOTE: If the trailer and/or axle weight has changed since your last trip, adjustments to the spring bar chains may be necessary.

Unhooking

1. Park the towing vehicle and trailer in a straight line on firm, level ground.

2. Support the trailer tongue weight with the trailer jack to ease the tension on the spring bar chains and allow for easier unlatching. Place the excess chain over the top of the latch. While holding the wrench firmly, release the locking pin handle on the latch by rotating or pulling out on it. Rotate the latch clockwise until the chain is released from the latch. Do this on both sides of the trailer.
   The latch will rotate quickly when the locking pin is released. Ensure you have control of the wrench when releasing.

3. Disconnect the spring bars from the hitch head by removing locking pins from each side. Remove spring bars from pivot tubes.

4. Unhook the trailer coupler from the hitch head.

5.  Remove the hitch pin and clip from the hitch receiver.

6. Remove the hitch head/receiver mount assembly from the receiver tube.

WARNING
DO NOT exceed the vehicle manufacturer’s specification for trailer gross vehicle weight or tongue weight as this may cause a serious accident and/or injury while towing. Also, be aware that some receiver hitch manufacturers have different weight capacity ratings depending on the use of a weight- distribution hitch or not.

Troubleshooting

Issue: After coupling the trailer to the hitch head, the tow vehicle squats, and the front of the trailer dips.
Resolution: If necessary, raise the chains of the spring bars up by one link.
Issue: After coupling the trailer to the hitch head, the tow vehicle is level but the front of the trailer dips.
Resolution: Adjust the hitch mount receiver higher. Each adjustment up or down equals 1-1/2″.
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.
Resolution: For all truck models with factory sway control, it is suggested that the sway control be disabled for the best performance of the Blue Ox® SwayProTM.
Issue: The ride is excessively rough.
Resolution: Spring bar chains are too tight or the spring bars are too stiff for your tongue weight. Be sure the spring
bar chains are set properly. Verify that the spring bars are properly rated for your tongue weight.
Issue: Experiencing excessive tow vehicle movement.
Resolution: Recommend that the tow vehicle tires are inflated to 90% of max inflation state on tire sidewall.
Support the Trailer Safely While Making Any Adjustments
Properly Adjusted System Overly Adjusted System
Light on the rear and heavy on the front – loosen chains, one link at a time, until the towing vehicle is level.
Under Adjusted System

RECEIVER HEIGHTS

Heights may vary slightly from what is shown depending on the brand of hitch ball used.

Maintenance of your SwayProTM

Maintenance
Check grease zerk on the front of both bar pivots before each use to ensure they are not dry. We recommend using a couple of pumps of molybdenum grease on each bar pivot, at least twice a year. Wipe away excess grease after application.
Periodically grease the hitch ball with molybdenum grease.

Things To Know
The towing vehicle’s loaded ball height should never be greater than it’s uncoupled height. Front-wheel overload and loss of rear-wheel traction can occur and can lead to unstable handling, reduced braking ability, and a tendency to jackknife when turning and braking at the same time.
DO NOT attempt to tow any type of trailer behind another trailer. Towing multiple trailers may cause severe instability, loss of control, and/or structural failures.
Handling and control of your towing vehicle and trailer is greatly improved when the cargo is properly loaded and distributed. It is recommended to have a tongue weight of 10-15% of the gross trailer weight.
Always use safety chains while towing. Cross chains under the coupler for proper installation and to prevent the tongue from dropping to the ground. Only allow enough slack in chains for tight turns, the chains should not drag on the ground. To alleviate slack, twist chains equally from the hook end. Safety chains should be rated at equal to or greater than twice the maximum gross trailer weight rating (GTWR).
