Weight Distributing Hitch

Create a stable ride for your tow vehicle and trailer with a weight-distribution hitch. Adding spring bars to your towing system applies leverage, which transfers the load that is pushing down on the rear of your vehicle to all the axles on both your tow vehicle and your trailer, resulting in an even distribution of weight throughout. The result is a smooth, level ride, as well as the ability to tow the maximum capacity of your hitch.



Selecting a Weight-Distribution System

The tongue weight rating is the most important factor in determining which size weight-distribution system you should use. If the bars of the system you choose are rated too high for your setup, they will create a rigid ride, which can result in a bouncing trailer. If, on the other hand, the bars are not rated high enough, the system will be unable to properly distribute the weight, rendering it virtually useless.


To determine the proper weight rating for a weight-distribution system, you must first determine your trailer's tongue weight. Then add to that the weight of the cargo behind the rear axle of your tow vehicle. These two measurements make up the tongue weight rating for a weight-distribution system.


Serrated Washer System

Unique Features of Reese Trunnion-Bar Weight Distribution

The easy-to-use, serrated washers on the Reese system make adjusting the tilt of the weight-distribution head a snap. This is a huge improvement over the standard pin-and-washer method, which involves piling washers - one on top of another - onto a difficult-to-access pin. The serrated-washer system lets you easily loosen, adjust and tighten a single washer and nut on either side of the head for simple, secure positioning.



The trunnion spring bars of this system slide into the weight-distribution head for quick, easy installation. With a tapered design and hot rolled steel construction, these bars offer superior flex, ensuring a smooth, controlled ride for both your tow vehicle and your trailer. In addition, these specially designed bars have rounded, hooked ends, making them the only kind of spring bars that can function with Reese's active-style, dual-cam sway control (sold separately).

High-performance system is designed to offer the best in weight distribution with an easy-to-adjust, forged head; a raised ball platform; and flexible, powder coated steel, trunnion spring bars. Adjustable shank included. Hitch ball sold separately.

This worked great. I gained about 2 1/2 inches on the rear lift , both the front and rear wheel well are at 36 1/2 off the ground . what a difference . Trailer is a little higher then level, not much, but with a quick adjustment that can be rectified. Delivery was on time and working with Briana was a pleasure. I emailed all the specs and the correct unit was recommended to me which is the one I purchased.



by:

Excellent customer service, Steve was knowledgeable and courteous. Fast delivery. Great quality. Adjustable chains work well for varying loads on my 10K car hauler.

Hitch is working great on my 10,000 lb. car hauler. Have hauled loads ranging from a tractor, loader, and tiller to an SUV with no issues.



by:

The folks at etrailer were very helpful on selecting this Reese hitch. Great people there. Thank you for all your help.



by:

Excellent delivery speed, unfortunately we had to wait until last week to have the trailer delivered. Used the hitch 3 times and are very pleased with the ease of installation. Enjoyed the heavy duty bar to over center the distribution bar. Used the same trick I used on previous hitches - place a bicycle handlebar grip on one end of the bar - much more comfortable. First time with trunnion bars - I'll never go back to the bent bar type with the snap pins and flexible clips - I've had to replace them several times - a real pain to drill out the rivets and find new ones. Very satisfied with hitch. Pulling a 24' Outdoor RV - "Timber Ridge" - 8000 GVW with 900 lb tongue weight with a Ford F250 Diesel. Pulls like a dream!



by:

I am very happy with the Reese Weight Distribution System that
I purchased from E-Trailer.

Even more... I got exceptional customer serviced from the staff and Technical Experts that I contracted.

I have included some installation tips in the attachments & a photo of what it is all about!



by:

After our third trip with this hitch it has performed great. This is almost exactly the same hitch that we have had for over 20 years so hopefully we will get 20 plus out of this one. Our only dissatisfaction is that the hold pins are very difficult to insert. As always the service of etrailer has been terrific.

After a year of use its still performing great.



by:

One of the nuts supplied to attach chain to trunion bar was not self locking. Otherwise this was bought because I have next larger version for a different trailer and have been pleased with it. The service was great in that the ball I ordered was out of stock and they notified me immediately and suggested an alternative ball that met my needs.

Works well. I like the easy adjustability of the chains for different loads as the trailer is used for many different items.



by:

Super hitch easy to set up and install. Easy and very informative instructions. Hooked up took a test drive worked so well I thought this can’t be true. Made an adjustment on the chain link and OMG what a big difference, not for the good though. Went back to the instructed set up perfect. Love it.



by:

We ordered the the weight distribution kit and hitch for a new camper on May 20th. We were going camping on the 26th of may and still had not received confirmation of shipping on the 23rd. My wife called and spoke to Sandy who advised that the online order dept was very backlogged but that she would check into getting it shipped right out for us. We received the hitch on the 25th and were able to get it hooked up and ready to go for the memorial weekend camping trip. Excellent product but more importantly to us was the above and beyond customer service we received.

Great product!!!Very well built.



by:

Another great Reese Product.
Installed
on a Tundra towing a Flagstaff Tent Trailer with a toy deck. I was having problems with the load sinking my truck and trailer. With the distribution system installed it is now towing very nicely. I had to increase the length of the chain by 1 link due to the way that the hitch on the trailer was built. I would buy and use another one with NO hesitation.



by:

The product, for how much steel it consists of came to my front door step completely unscathed. The packaging was flawless. After the cursory inspection, I began laying out the parts readying myself for assembly. The instructions were thoughtfully crafted and easy to follow.
Once mounted and setup, I took the trailer for a test pull. My trailer is a 26' enclosed car hauler. I put my wife's car in the trailer (her car is relatively small and probably only ways 2500 lbs give or take) and pulled 5 miles of curvy roads and about 10 miles of freeway. The system is confidence inspiring! I would whole-heartily recommend this product. It arrived quickly mounted easily and inspires confidence. What more could you ask for?



by:

The hitch is plenty heavy duty and worth the money. Makes a big difference when driving with a heavier trailer when compared to a conventional hitch.

Delivery of the hitch was fast too!!



by:

Appears to be good quality and easy to install - just need some time and don't rush the process. Have only used it once on a short trip and seems to be good. I noticed that the ride seems stiffer than with the curve bar type that I had prior - the bars are bigger and at a different point and do not appear to flex much. Shipping was faster than I expected for a heavier package. I will know how it performs after taking a longer trip.



by:

Great product instructions easy to follow, easy to install. It was a backordered product but came in a week earlier that expected. Packaged well though box was ripped in during shipping, watch out for the shim (optional shim Kit) that comes with the kit, almost threw it out was stuck loose in the bottom of the box.



by:

Very heavy-duty. Superior quality. etrailer's customer service is outstanding! They agreed to price match, shipped immediately, great communication, excellent follow-up. Love doing business with this company.



by:

This has made hauling our trailer a lot easier.
The trailer is a 24 ft enclosed, used mainly for racing.



by:

purchased this to replace my old load leveler. when I bought a new bunkhouse w/ a tipout the old 8000# wouldn't handle it. it was easy to put together and the hook is a breeze. the price was excellent and delivery was very quick.



by:

We're first time horse trailer owners and took the recommendation of EquiSpirit as to where to purchase the necessary equipment. We have been very satisfied with your service, your speedy delivery and no delivery charge on the heavy items.



by:

I ordered a Reese Weight Distribution Hitch from etrailer and it was shipped the same day. It arrived in great shape, I'm very satisfied with my purchase. The online price at etrailer was substantially less than what it would of cost locally.



by:

Great product and quick delivery. I had the same exact hitch for my travel trailer and it served us well.



by:

Excellent quality, forged not cast. Quick shipping, knowledgeable sales staff. I would highly recommend e trailer.



by:

Product appears to be of top quality and is very well built. I am hoping that it will shift more of the weight to the front of the truck and level it out. I will find out this spring when the towing season starts.



by:


Very fast service and its just
what I was looking for, Thank You

  • Should Weight Distribution Spring Bar Chains be Tight When the System is Installed
    On a weight distribution system that has spring bars hanging from chains, once you engage the spring bars and lower the jack the chains will be tight. It does sound like some adjustments need to be made though since you should have about 5 chain links from the hanger to the spring bar. You should be able to back up without remove the bars on a system like # RP66542 so it does sound like it is either a little too tight and needs to be adjusted or the system is not rated properly for the...

  • What is the Torque Rating for the Bolts on the Head of Reese Trunnion Bar Weight Distribution 66542
    The Reese weight distribution system # RP66542 uses 3/4 inch bolts to hold the head to the shank. The instructions, linked for reference, state the torque rating. The instructions that are linked are always going to be the most updated version so even if the manufacturer changes something in them you will still be able to see the latest version using that link. Torque specs are currently on page 2 of the linked instructions.

  • Weight Distribution Setup Final Measurements Recommendation
    Since they say to get the final measurements to settle evenly within about a 1/2 inch I would say you are pretty close but could stand to reduce the number of links between the hook and spring bar.

  • Weight Distribution System for Towing 7,000 lb Trailer
    When picking out a weight distribution system you'd want to aim for the weight range needed for how your trailer is loaded to the heaviest you'll be at. I recommend a system with a wide range like the Reese Weight Distribution System part # RP66542 which has a range of 600-1,200 lbs which would be ideal for you since you'll have a few different tongue weights depending on how you load it.

    Typically, you would want to choose a weight distribution system based on the loaded and ready to tow tongue weight of your trailer.

    Great question! Ford, GM and Ram use a similar nomenclature for their full-size trucks. • For GM and Ram, 1500 is a 1/2 ton, 2500 is a 3/4 ton and 3500 is a 1 ton. • For Ford trucks, the F-150 is a 1/2 ton, the F-250 is a 3/4 ton and the F-350 is a 1 ton truck. You have a 3/4 ton truck.

    The best way to select a weight distribution system for towing your 32 foot Cavalier travel trailer with your 1998 Dodge Ram 3/4 ton truck is to weigh the trailer when it is fully loaded and ready to tow. When weighing the trailer you will need to determine the gross trailer weight and the gross tongue weight, and add the weight of anything you may need to load behind the rear axle in the bed of your Ram to the tongue weight. Armed with this information you can select a weight distribution...

  • Can a Weight Distribution System Install onto a Standard Ball Mount
    The head of a weight distribution system will need to bolt to a weight distribution shank. It would have no way of installing to a standard ball mount. The reason we sell some systems without shanks is for people who need a shank with more drop than the standard shank that comes with the systems, this way they can pick out the amount of rise/drop they need. Since you do not have a shank you will need one to install a WD system. I attached a page that has all of the weight distribution...

    If the weight of the fully loaded trailer (including water and propane tanks) is below the manufacturers tow rating of the vehicle, the Commander will tow the trailer with no problems.

  • Weight Distribution System Recommendation for 6,500 lb Trailer with 8 inch Tall Frame Channels
    Since your frame channels are taller than 6 inches you'd need to use a weight distribution system like the Reese # RP66542 that has frame clamps that attach to the top of the frame and does not need to attach around the entire frame channel. This also won't damage the paint of your trailer frame and has a tongue weight range that would work well with a trailer that weighs between 6,000 and 6,500 lbs.

    To install a Reese Snap-Up Bracket, like part # 58392, on an I-Beam trailer you will not need to cut the frame but have an experienced welder add some extra metal where the bracket will sit on the trailer frame. This will simulate a regular trailer frame and will allow the Snap-Up bracket to be safely used.

So it would be best to replace the entire system Bob. A system like the Reese part # RP66542 would work great as it has a tongue weight range of 600-1,200 lbs which should match what your camper has well.

    Yes, you can bolt on the weight distribution brackets from system # RP66542. They can also be welded on.

Also one important tip I can offer is to make sure the brackets are in exactly the right place before drilling holes.
