    Pro Tip: Before you invest in a weight distribution hitch, make sure your cargo is evenly loaded in your trailer to keep the weight balanced. If you still have a hard time even after balancing your tongue weight, a weight distribution hitch should help.


    Easy to Upgrade to Active Sway Control

    Easily upgrade this weight distribution hitch with the Reese Strait-Line dual-cam sway control

    • This system doesn't control sway out of the box - but you can remedy that later on
    • The bars are specifically made to work with Reese's premium Strait-Line sway control system
      • Just add on the dual cams and get better control when cornering, swerving, and dealing with wind
      • Great sway control, but can get pretty noisy when you make turns
    • For a more economical option, you can add a bar-style friction sway control to either side of your trailer (or both sides, if you have a really long trailer)
      • Uses friction to force your trailer back in line when it gets pushed off course
      • Has to be removed at times (e.g. in the rain or when you're backing up), but its adjustable tension is a plus

    Note: Neither of these sway control systems will work with surge-type actuators.


    People often conflate sway control with weight distribution. It's understandable because most weight distribution systems on the market today do solve issues with sway.


    This system will give you weight distribution only. It doesn't have any sway control built in. But if you find that you need sway control later, it's super-easy to upgrade to Reese's Strait-Line sway control system by adding on the dual-cam brackets (RP26002 - sold separately).


    Get the Full Setup: If sway control is something you need right now to keep your trailer from getting squirrelly, take a look at RP66074 for a complete Strait-Line system.


    A view of a Reese Strait-Line weight distribution system shows the flexing of the bars under weight.

    Alternatively, you can add a friction sway bar (sold separately) for a little more reinforcement. This option allows you to easily dial in the amount of tension with the turn of a handle. This adjustability is nice (even if it takes you a few trips to get it just right), but it doesn't play well with surge-type actuators (neither does the Strait-Line dual cam system), and it will have to be removed when backing up any time you tow on wet or slippery roads.


    Simple Setup with Serrated Washers

    A top-down view of the Reese weight distribution hitch shows the design of the head and serrated washer feature

    • No more piling on washers
    • Exterior, serrated washers let you adjust the head without having to take everything apart

    The easy-to-use, serrated washers on this 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 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.


    Why Use a Weight Distribution Hitch?

    Diagram showing weight distribution on a truck and towing a camper

    • Prevents uneven tire wear on your vehicle and trailer
    • Keeps the rear of your tow vehicle from sagging
    • Lets you tow to the max capacity of your trailer hitch
    • Stops your headlights from pointing up at the sky
    • Gives you control over steering your rig

    Selecting the Right Weight Distribution System

    • Think "Goldilocks"
      • If you go for overbuilt, you'll have a rigid ride
      • If it's not strong enough, it's virtually useless
    • Let your tongue weight be your guide

    Your tongue weight is the first thing you need to know when figuring out which weight distribution system you need. Most people think that if they get the highest-rated system possible, it'll be smooth sailing. But actually, this will create a rigid ride and a bouncing trailer. On the other hand, if the system isn't strong enough, it won't be able to distribute the weight properly, making it virtually useless.


    Once you know your trailer's tongue weight, add it to the weight of the cargo behind the rear axle of your tow vehicle. Then just choose a weight distribution system rated for that combined tongue weight.

    Install is easy but you will need a high torque drill. I took it to the shop and they had it on in 20 minutes. I am very pleased with the improvement in safety and stability and with the ease of use and removal. It is exactly what my Avalanche needed to haul heavy loads! If only I could bolt on a 6.0L ...

    Had these installed by a dealer and drove a few hours to a campsite this spring. Only the second time driving a camper and first time on a major highway. White knuckle ride for the first half hour then realized the camper wasn't swaying or rocking and started to relax. Coming home two days later I started out relaxed and enjoyed the drive....even passed a truck!

    • Recommended Solution for a Trailer W/ Pre-Existing WDS Setup
      Aaron, we do have the Replacement Trunnion Bar for Curt Short-Arm Weight Distribution System # C17336 which are 28 3/8" long that could potentially be what you're looking for, but honestly without knowing for sure you'd be taking a gamble. I'd honestly just recommend starting fresh and cutting those brackets off. It's going to be a bit more work upfront, but long term it's going to be the best decision. If you can tell me what sort of tongue weight we are working with, I'd be happy to...

    • Can a Weight Distribution System be Used on an I Beam Trailer
      You will need to use a standard weight distribution kit like the Heavy Duty Trunnion Weight Distribution System # RP66131 for your I-beam trailer. This system would be rated perfectly for your 10k trailer if it was going to be loaded near it's capacity. This system has a tongue weight range of 800 lbs - 1,500 lbs which would be most likely what you would have. For a shank you would then want the part # RP54977.

    • Installing Weight Distribution System on I-Beam Trailer
      I-beam trailers like what you have do make it a bit tricky to add a weight distribution system, however it can indeed be done with a little modification. In order to use a standard weight distribution system like the Reese # RP66131, you will need to have steel plates (5 or 6 inches wide) welded to box the frame out on the trailer. Once the plates are welded on, you can use a chain hanger kit like the Reese # RP58305 to attach the system. I do recommend having an experienced welder perform...

    • Why Not Directly Weld On Weight Distribution Brackets to Trailer Frame
      The reason to install steel plate to enclose an I-beam trailer frame to allow use of a weight distribution hitch's lift brackets is that this method makes for easier replacement of a bracket should one fail. If you directly weld the modified lift bracket to the I-beam then you will have a tougher time of removing it should it ever fail. Using the steel plate means you can bolt/clamp one on and more easily remove it if the need arises.

      I certainly can recommend you a weight distribution system. Thank you for giving me all the weight information for your trailer as that makes it very easy to pick out the correct system. The Reese Strait Line System part # RP66084 would be the system I would recommend.

    • Recommended Weight Distribution for Motor Home Towing 13,000 lb Trailer
      If your motorhome does indeed have a hitch with a 10000 lb capacity, it means that the hitch is capable of towing a trailer weighing up to 10000 lbs. To confirm this, the hitch should have a sticker or plate on it listing the capacities. The tongue weight capacity should also be listed. Tongue weight is the amount of weight that can safely be suspended from the receiver (or the maximum downward force exerted). The hitch might also list a capacity for use with a weight distribution (W/D)...

    • Choosing Firestone or Timbren Suspension System for Towing 3-Horse Trailer
      Given the choice between the Timbren system ( # TFRTT1502D for 2wd or # TFR150D for 4wd models) or the Firestone # F2350, I'd choose the Timbrens because although the springs won't have any effect on the vehicle ride when there isn't load being applied, they'll get progressively stiffer as more weight is added. The Timbrens have a 6K capacity, but you'll be limited by the payload capacity of your truck. The Firestone springs don't carry a weight capacity, per my contact at Firestone. If...

Then for a weight distribution system you'd want the # RP66131 which has a tongue weight range of 800 to 1,500 lbs. For a hitch ball you'd want the part # C40030 and for a shank part # RP63971 and you'd be set. Curt...

      Since you have propane tanks above your RV frame in the location that the spring bar hangers would need to install you'd want to use a system that instead uses chains like the part # RP66131 for how the bars attach to the frame hangers and then instead use bolt on brackets like the # RP58305 which attaches to the side of the frame and does not require clearance above the truck frame.

    • Weight Distribution for a 2006 Ford F-250 and 9,900 Pound Trailer
      To choose a weight distribution system you will need to go by the total tongue weight of the set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that the weight of anything loaded behind the rear axle of the tow vehicle. For a trailer that maxes out at 9.900 pound gross trailer weight the tongue weight would be 990 to 1,485 pounds.

Also, having it properly set up for the trailer is very important. With that being said, if the tongue weight of your setup is going to fluctuate within the range of the weight distribution system quite a bit you will have to set it up differently based on that.

      To choose a weight distribution system you will need to go by the total tongue weight of the set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that the weight of anything loaded behind the rear axle of the tow vehicle.

      To determine the maximum trailer weight that can be towed, you will need to subtract the GVW (gross vehicle weight) from the GCWR (gross combined weight rating). The GVW is the curb weight of the vehicle, plus the cargo. GCWR is the maximum allowable weight for the trailer plus the tow vehicle.

But if the sag is from towing a trailer a much better solution is a weight distribution system. This will take the tongue weight of the trailer and partially distribute it to the front axle of the vehicle which will give it better braking and handling characteristics than with suspension enhancement.
