The Blue Ox BXW1506 WghtDstHtchCntrl is a weight-distribution system designed to balance the load of your trailer and provide a more level ride. Its unique design features four integrated points of friction that help to reduce sway and improve control while towing. This system comes with an adjustable shank that fits 2-inch trailer hitches and clamp-on brackets that require no drilling, making it easy to install. Its durable powder coat finish ensures it can withstand harsh weather conditions, keeping it in top shape for longer.
Blue Ox is known internationally for recreational and commercial towing products, manufacturing in Pender, Nebraska since 1925. The line covers tow bars and vehicle-specific baseplates for flat towing behind a motorhome, sway control and weight distributing hitches, supplemental braking accessories and towing wiring, backed by patented designs and long-standing customer service.
Blue Ox has manufactured since 1925 and is recognised internationally for towing products and customer service. The company operates from Pender, Nebraska, where it grew out of Automatic Manufacturing Co., a business that started with cattle oilers and developed into agricultural equipment, tractor accessories and trailer towing hardware. That agricultural engineering heritage still shows in how the towing products are built, and the company holds patents across weight distribution, fifth wheel and tow bar designs.
Flat towing is the discipline Blue Ox is best known for. Towing a car with all four wheels on the ground behind a motorhome demands a system that stays rigid under braking, articulates properly over uneven ground, and connects to the towed vehicle at points strong enough to take the load. Blue Ox tow bars handle the first two, with self-aligning arms that latch under tension and release without a struggle when the load is off them. Vehicle-specific baseplates handle the third, engineered per make and model to tie into structural mounting points behind the fascia.
The wider flat towing range covers supplemental braking systems, safety cables and the accessories that make a complete legal setup, along with baseplate wiring and dinghy towing harnesses that pass lighting signals to the towed vehicle without back-feeding its electrical system.
For conventional trailer towing, Blue Ox weight distributing hitches with integrated sway control transfer tongue load onto the tow vehicle's front axle and resist the yaw that crosswinds and passing trucks induce.
The company describes its foundation as customer service, designing around what owners actually ask for, and it runs an RV park adjacent to the factory where customers can stay. Sister operations at the same Nebraska site include Automatic grain roller mills and MAD-RAMPS pivoting ramp systems.

The SwayPro™ fits standard 2" receiver hitch mounts. It is available with 7-hole, 9-hole, or 11-hole receiver configurations in various lengths (9", 10", 12", or 18"). Verify your receiver hitch configuration before purchasing.
BXW0556: 550 lbs; BXW0756: 750 lbs; BXW1006: 1000 lbs; BXW1506: 1500 lbs. A minimum tongue weight of 200 lbs is required for all models.
Torque wrench, tape measure, 1/2" wrench, 3/4" wrench, 1-1/8" wrench, and 1-1/8" socket.
Yes. Air-ride shock absorbers, air springs, or automatic leveling systems on the towing vehicle must be disabled or deflated to the manufacturer's minimum recommended pressure prior to SwayPro™ installation.
250 ft/lbs.
Professional installation is recommended. The manual states: "We recommend that this product be installed by an authorized Blue Ox® Professional Installer. Improper installation and/or operation can create a hazard which can cause serious injury, property damage or death. Improper installation and/or operation will void the warranty."
Tongue weight should be 10–15% of gross trailer weight. This is recommended for proper handling and control of the towing vehicle and trailer.
The SwayPro™ accepts 1" or 1-1/4" ball shanks. A 2-5/16" x 20K chrome hitch ball is pre-installed on the hitch head.
No. Sway prevention is built into the SwayPro™ system and no adjustments are required. The spring bars automatically pivot on the hitch head to balance and prevent trailer sway as the trailer tries to sway.
No. The spring bars are designed to deflect 2"–3" on a properly set system to create the necessary load for an enjoyable ride. The bars will always return to straight and will not remain bent.
Spring bars are marked with a dot system on the shank end: no dots = 350 lbs; 1 dot = 550 lbs; 2 dots = 750 lbs; 3 dots = 1000 lbs; 4 dots = 1500 lbs; 5 dots = 2000 lbs.
The hitch ball height must be the same as or 1" higher than the trailer coupler height. However, for optimal towing performance, it is recommended to set the ball height 2" higher than the top of the trailer coupler. Ram truck owners should reference their vehicle owner's manual for proper hitch setup instructions.
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. 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.
Release the rotating latch by rotating or pulling out on the lock pin handle. Using the provided wrench, rotate the bracket 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. Rotate the latch counterclockwise using the wrench until the lock pin engages in the lock pin hole. Adjustments to the number of links (advancement to the 10th or 11th link) may be necessary due to driving conditions or trailer changes.
Torque the 1/2"-13 square head set screws to 25 ft/lbs and tighten the jam nut. Do not use Loctite Red on the set screws.
1. Support the trailer tongue weight with the trailer jack. 2. Unlock the rotating latch bracket and release the spring bar tension on the chains. 3. Adjust the chains one link at a time to tighten or loosen. 4. Reapply spring bar tension by rotating the latches clockwise until the lock pin engages. 5. Lower the trailer tongue to be supported by the towing vehicle. Repeat until the towing vehicle is level. If the trailer is not level, each hole on the receiver mount raises or lowers the front of the trailer 1-1/2". Adjust the hitch head position on the receiver mount as needed and retorque the 3/4" fasteners to 250 ft/lbs.
If the trailer structure interferes with the pre-installed set screws, replace them with the shorter 1/2"-13 x 2" set screws provided in the kit.
The 2 quick links are for receiver hitches where the safety chains will not reach. Install quick links on safety chain loops mounted to the receiver hitch and tighten them.
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 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 rotating latches are tight on the tongue. 6. Support the trailer tongue weight with the trailer jack to ease tension on the spring bar chains. Attach the spring bar chains to the rotating latches with the appropriate chain link. Apply tension to the spring bar by rotating the latch counterclockwise until the locking pin engages. Do this on both sides. Before each tow, confirm that all bolts are tightened to specified torque specs.
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 tension on the spring bar chains. Place excess chain over the top of the latch. While holding the wrench firmly, release the locking pin handle by rotating or pulling out on it. Rotate the latch clockwise until the chain is released. Do this on both sides. 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.
Check the grease zerk on the front of both bar pivots before each use to ensure they are not dry. Apply a couple of pumps of molybdenum grease to each bar pivot at least twice a year. Wipe away excess grease after application. Periodically grease the hitch ball with molybdenum grease.
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; 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).
If the SwayPro™ hitch is in an accident, it must be replaced and not used again. An accident can cause unseen damage, and using it again could result in more damage or serious injury. Do not use the hitch if it is damaged or missing parts.
No. 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.
The towing vehicle's loaded ball height should never be greater than its uncoupled height. If the loaded ball height exceeds the uncoupled height, front wheel overload and loss of rear wheel traction can occur, leading to unstable handling, reduced braking ability, and a tendency to jackknife when turning and braking at the same time.
Blue Ox offers replacement kits for spring bars (350, 550, 750, 1000, 1500, and 2000 lbs), rotating latches (clamp-on, wrench, and bolt-around styles), hitch heads (pin style and underslung pin style), pins, and receiver mounts in various configurations. Replacement parts may be ordered through your nearest Blue Ox Dealer or Distributor. Use only genuine factory replacement parts; do not substitute homemade or non-typical parts.
The SwayPro™ is backed by a limited lifetime warranty. The original retail purchaser is covered for defects in material and workmanship under normal use and service for as long as they own the product. Coverage is valid only if the customer warranty card is returned within 30 days of purchase and a copy of the original invoice accompanies any warranty claim. The warranty does not cover incorrect or improper installation, improper use, modification, neglect, failure to maintain, misuse, accident, normal wear and tear, paint, or rust. Unauthorized modifications void the warranty.
Raise the chains of the spring bars up by one link.
Adjust the hitch mount receiver higher. Each adjustment up or down equals 1-1/4".
Excessive sway may indicate that the trailer is improperly loaded. As a guideline, the tongue weight should be 10–15% 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. 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 SwayPro.
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.
Recommend that the tow vehicle tires are inflated to 90% of max inflation state as shown on the tire side wall.
