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).

Video Transcript for Reese Weight Distribution - WD Only - RP66540 Review

Today we're going to be taking a look at the Reese Weight Disruption system. This weight distribution system has a maximum tongue weight capacity of six hundred pounds and a gross towing weight capacity of ten thousand pounds. It is designed to fit a two inch by two inch trailer hit receiver that's rated for use with a weight distribution system. It's going to be covered with a limited lifetime warranty. Now a weight distribution system is going to help evenly distribute weight over the axles over the tow vehicle and trailer, which is going to offer better stability and control. Ultimately it's going to create a more level ride for both the tow vehicle and the trailer, and it's also going to correct tow vehicle sag and it's going to improve steering and stopping. Now this system is going to feature trunnion spring bars that are hot-rolled and tapered for superior strength and flexibility.

These bars will flex appropriately over uneven terrain for controlled, even ride. The curved ends on the bars are designed for use with dual-cam sway control, part number RP26002. That is sold separately. The system will also work with friction style sway control, something like part number RP26660. It's got the attachment point right there for a system like that. The spring bar tension can be adjusted.

All you have to do is switch the links and the lift chains to fine tune the system. It's going to come with the snap up lever, which is going to help get the lift brackets in place. Once the chains are connected, that's going to help reduce the amount of lifting required by the trailer jack, so this just allows you to get the proper leverage needed to get those up and in place. The lift brackets, they're going to take up about five and a half inches along the trailer frame, and they will not fit trailer frames wider than two and a half inches. It's going to come with the set bolt.

It's a clamp-on design. No drilling required. You place this on, and then you tighten this down until it makes contact with the frame of your trailer and then give it another quarter of a turn, to fully secure that. Then in the up position, it's going to be held in place with these clips. Here at the head assembly, it does have a tilting feature. The desired tit or pitch is easily achieved with a serrated washer design, so no more having to pile on washer after washer to get the required tilt for your application.

It's going to have a washer located on each side, here on that upper piece of hardware, and the washers is going to have serrated teeth, and then on the head assembly are going to be grooves. Those all match up once the hardware's tightened. That's going to be what secures the head assembly into position that you need it to be in for your application. It's also going to have a forged, raised ball platform on the head, which is going to eliminate the need for a raised hitch ball. Now everything is going to be steel construction, nice powder-coated finish to resist rust and corrosion. The shank right here is included. This is an adjustable shank that can be used in the rise or drop position. The shank is made from solid steel with that durable, powder-coat finish on it as well. The shank is going to feature a six hole design for adjusting the head assembly. The distance between those adjustment holes on center is going to be an inch and a quarter. It does come with your hitch pin and clip to get your unit installed inside of your hitch. Then here, it's going to have two hitch pin holes. You can simply just choose whatever one works best for your application. The distance that we have from the center of those hitch pin holes to the center of where the ball would mount, is going to be around fourteen inches. The system does come with everything that you see on the table. Your hitch ball sold separately. This is designed to accept hitch ball with an inch and a quarter diameter shank, or you can choose the hitch ball with the one inch shank diameter, but you will have to use the included reducer sleeve, to reduce that opening size. It's going to come with a shim, that's this right here. This is designed to be used if you notice a gap between this portion and the head assembly. It's got the holes in there that lines up with the two bolts for the mounting hardware of the head assembly to the adjustable shank. You would just place that in there and again, that's designed to fill the gap between the head assembly and the mounting points on the shank, if needed. Now with the system fully installed on your application, you are able to back up your trailer. This is compatible with electric brakes. It's also compatible with surge or hydraulic brakes, but please keep in mind, that's only when used without any sway control device. You always want to be sure to maintenance your system according to the included manual and instructions. To make it easier, there are two oil holes right here at the top of the head assembly on this top plate to lubricate the upper portion of the trunnion bars. Now I talked a little bit earlier about the lift brackets. There are optional mounts that take up less space on the trailer frame. Those are available, they're sold separately. They can be found here at etrailer.com. With the unit in the rise position and head assembly at the highest setting, we're going to have a maximum rise of about six and a half inches. It's measuring from the top of our shank, where the inside top edge of the receiver tube of your hitch, to the top of the ball platform. With it in the drop position, with the head assembly at the lowest setting, it's going to give us a maximum drop of about an inch and a quarter. That's going to do it for today's look at the Reese Weight Distribution System. Again, this has a maximum tongue weight capacity of six hundred pounds, and a gross towing weight capacity of ten thousand pounds.

Ordered this on Monday and received it today. Looks like it is well made and will be ready to tow my Rockwood 2280 2016 year with my 2015 Sienna minivan. I was originally going to tow using only the standard hitch and ball but after doing further research decided the weight distribution system was the way to go, particularly because the Sienna rides low to the ground normally. 620173

This system is sized properly for the amount of tongue weight that your trailer will have when fully loaded and ready to travel, and includes all of the items needed to get on the road.

This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached an FAQ on determining tongue weight for you to check out as well. You want to pick a system that has a tongue weight range that your loaded tongue weight falls right into the middle of. If your trailer weighs 3700 lbs when loaded that means...

  • Why are Some Trailer Hitches Rated for Weight Distribution and Others Are Not
  • Weight distribution systems are quite helpful for towing but not every hitch can be used with them. The issue is that the spring bar tension that the system puts on the vehicle and hitch can be too much and could potentially damage either. It's not that the vehicle itself wouldn't benefit from a WD system it's that the torque the system puts on the attachment points for the hitch and/or vehicle just would be too much.

  • Availability of Light Duty Weight Distribution Systems
  • We have very light duty weight distribution systems, but none of them will fit a 1-1/4 inch hitch since that hitch size isn't designed for the torque the WD systems can put on hitches. For a light duty weight distribution system that will fit a 2 inch hitch the Reese Light Duty part # 66557 is for tongue weights up to 400 lbs. If you need a higher rated system the part # RP66540 is for 200-600 lbs of tongue weight. For a 2 inch ball you would want part # A-90 and for a 2-5/16 inch...

  • Is Weight Distribution Needed For 2007 Ford Expedition Towing a Titan 3,000-Lb Loaded Trailer
  • A good rule to follow when deciding whether or not to use weight distribution is to remember that weight distributing systems should be used any time the trailer weighs more than 50 percent of the tow vehicles weight. So with the trailer at almost 2,000 pounds, and 1,000 pounds loaded on it, you are looking at about 3,000 pounds total trailer weight. Since the 2007 Ford Expedition can weigh as much as 7,700 pounds, a weight distribution may not be required for your setup, but you would...

  • Looks like the front of your trailer does have quite a bit of accessories mounted at the front of it so a bolt-on frame bracket style of system is going to be the easiest for us to recommend. The Reese brackets part # RP58305 would be a great solution for this with a Reese weight distribution system part # RP66540 would be a fantastic option. This kit has a tongue weight range of 200-600 lb which would work great with your 400 lbs of tongue weight. For a 2 inch ball you would want...

  • Your picture is a bit grainy so I couldn't tell for sure, but if there is a hole in the center of the a-frame for mounting a jack you are going to want to install a jack there and remove your side mount jack. The part # BD155300 has a wheel caster like your current jack does as well. With the jack off of the side of the trailer you would have clearance to install a WD system. Since you already have sway control the Reese Trunnion system part # RP66540 would be a great choice for a...

  • I wouldn't think so to be perfectly honest, but weight distribution will give you a better towing experience, maybe not a huge difference but it will make an improvement. I looked up the towing capacity of your truck and it looks to have a capacity of around 10,000 lbs which means towing a 3,200 lb trailer loaded would not be an issue at all. The benefits you'll gain though will be better braking and handling especially in an emergency situation. If I were you I'd tow the trailer without...

  • You want to pick out a weight distribution that has a tongue weight range that matches up well with the tongue weight of your trailer. Getting a system rated too high will result in an overly stiff ride, and if you go too low the system won't distribute any weight to the front axles. Right in the middle is ideal. For your 350 lbs of tongue weight the Reese Weight Distribution System # RP66540 would be ideal. This system has a tongue weight range of 200-600 lbs which would be ideal for...

Tongue weight is typically 10 t0 15 percent of the gross trailer weight (but could be more).

Both will serve the same purpose, you just have different styles of trunnion bars and the tilt adjustment function. The Reese System uses a serrated-washer design and the Pro Series System uses the stacked washers of traditional systems. The chain hangers # RP58305 can be used with either system. You will also need hitch ball # A-90 for a 2 inch ball or # 19286 for a 2-5/16 inch...

  • Weight Distribution for a 2009 Saturn Vue and 2,756 Pound Trailer
  • First, you need to make sure your 2009 Saturn Vue has a Class III trailer hitch with a 2 inch receiver that is rated for weight distribution like # 75556. When choosing a weight distribution system you will need to go by the tongue weight of the trailer when loaded and ready to tow and then add the weight of anything loaded behind the rear axle of the tow vehicle.

  • Solution to Eliminate Sag When Towing Ski Boat with 2000 Toyota Tundra
  • The Air Lift Ride Control Air Helper Spring kit, part # AL59530 is compatible with your current tire size on your Tundra.

This being said, an air spring kit is primarily meant to suspend a load carried in the vehicle. To overcome sag caused when the tongue weight of a trailer is applied to the rear of your vehicle, a weight distribution...

  • Suspension Enhancement or Weight Distribution for 2012 Dodge Grand Caravan Towing 21 ft Camper
  • The Timbren Rear Suspension Enhancement System you mention is primarily meant to suspend weight carried in the cargo area of the vehicle itself, but it would not necessarily be the best choice to act against the sag caused when the trailer is hitched to the vehicle. While the tongue weight does compress the rear suspension of the vehicle, it also unloads the front suspension which will reduce braking and steering performance.

  • Weight Distribution for a 2008 Kia Sedona and 2,700 Pound Trailer
  • First make sure that the hitch on your 2008 Kia Sedona is rated for use with weight distribution. Some of the hitches for your van are rated for weight distribution and some are not. If it is there will be 2 sets of tongue/gross trailer weight ratings. Based on the weights of the trailer you have provided a system rated for 800 pounds will not be the best option. I recommend something that is rated lower so that it will be more effective. Take a look at Fastway system # FA92-00-0450....
